Glossary of bicycling

This is a glossary of terms and jargon used in cycling, mountain biking, and cycle sport.

For ''parts of a bicycle'', see List of bicycle parts.

0–9

; 27.5 Mountain bike: A mountain bike with wheels that are approximately in diameter and are based on ISO 584 mm (650B) rims.
; 29er (bicycle):A mountain bike with wheels that are approximately in diameter and are based on ISO 622 mm (700C) rims.
;3:1 rule

A

; À bloc: Going ''À bloc'' means riding as hard as one possibly can, which can be risky as it leaves one in a state where recovery is needed, and therefore vulnerable to being attacked.
; Aero bars: Extension of the handlebars usually allowing the rider to rest their elbows and benefit from improved aerodynamics. Often found on Time trial bicycles.
; Aero racing bicycle: A type of racing bike that combines the aerodynamic features of a time trial bicycle with a road racing bicycle.
; All terrain tire: Off-road tire, or a bicycle tire designed to function well for varied terrain and uses.
; All-rounder: A racing cyclist who excels in both climbing and time trialing, and may also be a decent sprinter. In stage races, an all-rounder is likely to place well in the General classification. All-rounders are usually Team Leaders in both stage races and classics cycle races. The term all-rounder can also mean a bicycle designed to function well for varied terrain and uses.
; Alleycat race: A bicycle race typically organized by bicycle messengers or couriers. Alleycat races seek to replicate some of the duties that a working messenger might encounter during a typical day. The races usually consist of previously undisclosed checkpoints, which are listed on a manifest, that a racer will have to go to; once at the checkpoint, the racer will have their manifest updated. First racer to return with a completed manifest wins. Alleycats were first formalized in Toronto, Ontario, Canada, in 1989; however, messengers have been racing against each other for much longer. Recently, with the boom in urban cycling, many non-messengers have been participating in and organizing alleycat races.
; Arrière du peloton: From French, literally the "rear of the peloton" (main group of riders). Also called the Feu Rouge (red tail light) or Lanterne rouge.

; Booties:Fabric overshoes worn by cyclists to protect their feet from rain or cold.
; Bottom bracket (BB):The bearing assembly which allows the crank to rotate relative to the frame. May or may not include the spindle which connects the two arms, depending on the standard to which it was designed.
; Breakaway:''Breakaway'', or ''break'' in short, is when a small group of riders or an individual have successfully opened a gap ahead of the peloton.

; Chain gang: A group of cyclists cycling in a close knit formation akin to a road race, normally for the purposes of training.
; Chain slap: Annoying slapping of the bike's chain against the chainstays while riding over rough terrain.
; Chain suck: The tendency of a chain to stick to chainrings and be sucked up into the bike instead of coming off the chainring. Primarily caused by worn chainrings and rust on small chainrings, under high loads, and in dirty conditions.
; Chainring(s) : The front part of the drivetrain where the chain engages. May be composed of one to three gears.
; Chainstay: One of the two frame tubes that run horizontally from the bottom bracket shell back to the rear dropouts.
; Chase: A group of one or more riders who are ahead of the peloton trying to join the race or stage leader(s). There may be none, one, or many chases at any given point in a race.

; Crack: When a cyclist runs out of strength or energy, they are said to have cracked. Compare with hit the wall.
; Crank arm: A crank. One of the two arms of a crankset. Each arm connects a pedal to the bottom bracket.
; Crankset: The bicycle drivetrain assembly that converts the rider's reciprocating pedaling action to rotating motion. It consists of two cranks (or arms), one or more chainrings (or chainwheels), plus the stack bolts that connect them. Sometimes the bottom bracket is included.
; Criterium: A race on a closed short distance course with multiple laps. Often a four-cornered course; often includes ''primes'' (French for "bonus" and rhymes with 'seems') which are points or prizes for intermediate laps. Course length varies from 800 meters to 5 kilometers.

; Cyclability: Degree of ease of bicycle circulation.
; Cyclocross: A form of bicycle racing that consists of many laps of a short course featuring pavement, wooded trails, grass, steep hills and obstacles requiring the rider to quickly dismount, carry the bike past some obstacles and remount.

D

; Danseuse: (french: danser – to dance) Riding out of the saddle, standing up, usually in a taller gear than normal, and rocking side to side for leverage. The phrase ''dancing on the pedals'' is related.

; Door prize: A collision with the door of a parked car, typically opened suddenly in the cyclist's path.
; Dossard: Race number attached to the back of a competitor's jersey.
; Drafting: To ride closely behind another rider to make maximum use of their slipstream, reducing wind resistance and effort required to ride at the same speed.

; Drop:
#(or drop-off) A steep section, or sudden drop on a mountain bike trail.
# To be dropped is to be left behind a breakaway or the peloton for whatever reason, usually because the rider cannot sustain the tempo required to stay with the group. To drop someone is to accelerate strongly with the intent of causing following riders to no longer gain the benefit of drafting.
#(or "Drops") The lower part of the handlebars on a road bike; they run parallel with the top-tube.
; Dropout: The slot, of various sizes and orientations, in the frame that the axles of the wheels attach to.

E

; Echelon: ( French) A line of riders seeking maximum ''drafting'' in a crosswind, resulting in a diagonal line across the road.

; Endurance bicycle: see sportive.
; Enduro: A mountain bike race where riders are timed on stages that are primarily downhill, with neutral "transfer" stages in between. The transfer stages usually must be completed within a time-limit, but are not part of the accumulated time. Also see funduro.https://www.singletracks.com
Falkirk Funduro.
; Espoir: (French: ''hope'') Age class for riders 19 to 22. Also called U23.
; Étape: A stage of a stage race.

F

;Faceplant: When a rider impacts their face in a crash.
; Fall line: The fall line describes the direction on a mountain or hill which is most directly downhill. A trail is said to follow the "fall line" if it generally descends in the most downward direction, rather than traversing in a sideways direction.
; False flat: A low-gradient climb, usually occurring partway up a steeper climb. So-called because while it may look deceptively flat and easy (especially after the steep climb preceding it), it is still a climb.
; Fast finisher: A rider who has superior sprinting speed over the last few hundred meters of a race.
; Feed zone: In road bicycle racing, a location along the course of a long race where team personnel hand musettes containing food and beverages to passing riders. In mountain bicycle racing, a limited section of the course in which riders may accept food from non-racing assistants. Sometimes this is combined with the technical assistance zone if one exists.
; Field: A group of riders, also known as a peloton.
; Fixed (or "Fixie"): Slang for a fixed-gear bicycle.
; Flamme rouge: A red flag displayed with one kilometer remaining from the finish line of a race. Usually suspended over the road.
; Floating disc rotors: In a two piece disk brake rotor, floating rotors keep the braking surface cooler. A steel braking surface is riveted to an aluminium piece. When a rotor is subjected to serious heat, it expands.
; Follow a wheel:The ability to follow a wheel is the ability to match the pace of riders who are setting the tempo. Following is easier than pulling or setting the tempo and the term can be used in a derogatory manner, e.g. "S/he only ever followed".
; Fork:Part of the frameset that holds the front wheel. Can be equipped with a suspension on mountain bikes.
; Frameset:The bicycle frame plus the front fork. or a bicycle frame with shock and fork included, or just the including the shock if it's a full suspension frame.
; Fred:Disparaging term for any cyclist who "is marching to the beat of a different drummer", or a novice cyclist.
; Funduro:An informal Enduro, ridden more for fun, or sometimes as training for a real Enduro.
; Furious cycling:Alternatively ''wanton and furious cycling'' or ''furious riding''; a statutory offence in England and Wales and Northern Ireland applied to cyclists who cycle over the national speed limit.

G

; Gap: A distance between two or more riders large enough for drafting to no longer be effective. Also used as a verb (US English); for example: "Contador has ''gapped'' Armstrong!". It's much easier for a stronger rider to pull ahead of others once a ''gap'' has been achieved; without a gap, the others can draft along using significantly less power to sustain the same speed as the rider in front. While gaps are usually achieved through ''attacks'', on mountain climbs, where slower speeds means the advantage of ''drafting'' is much less significant, riders are often gapped who simply cannot maintain the ''tempo'' of the faster riders.

; Gap jump: A jump with separate take-off and landing zones, having a "gap" between the ramps.https://www.trailforks.com
Technical Trail Features.
; G.C.: Abbr.: general classification. The timing splits used to determine who is winning in a stage race, and the overall position of riders relative to the leading rider. Riders can attack in stage races for time rather than winning the day's stage. They are said to be "riding for G.C.". In such circumstances alliances can form where some riders in a breakaway will work to help others win the day's stage despite not contesting the finish as the overall gap the breakaway gains helps them "on G.C."
; Granny Gear: Two meanings related to each other:
#The lowest gear ratio on a multi-speed derailleur bicycle; smallest chainring in front and the largest at the back.
#The smallest chainring on a crank with triple chainrings.
; Gravel bike: A type of racing bicycle similar to one used in cyclo-cross but geared towards gravel roads, common in the United States and Europe.
; Green Jersey or Maillot Vert: In some staged races, a jersey awarded daily to the rider who leads on points. Originating in the Tour de France in 1953, it is called in French ''le Maillot Vert''. This is the current usual usage; historically, Green jerseys have sometimes represented different achievements or honours.
; Grimpeur: See Climbing specialist
; Group or Groupset: A set of parts usually from a single manufacturer, usually consisting of, at least, bottom bracket, brakes, derailleurs, hubs and shifters, and possibly also including headset, pedals, and seatpost. A ''kit'' is a group, plus everything else a frameset needs to make a complete bicycle.
; Gruppetto: See autobus.
; Guttered: In an echelon, where the size of a draft is limited by the width of the road, to be left with no good position to join the group and be sheltered from the crosswind.

H

; Half-wheel or Half-wheeler: A rider that rides half a wheel in front of another on training rides and group rides. No matter how much the pursuer speeds up to keep up with them, they stay that distance ahead. Usually these people are frowned upon and less desirable to ride with.
; Hammer: To ride fast.
; Handicap: A style of road racing in Australasia where riders are given different start times, calculated based on their previous performance, so that slower riders have a chance of winning.
; Hardtail: A bicycle that does not have a rear suspension system.
; Headset: The bearing system in the head tube within which the handlebars rotate.

; Hors délai (HD): French for "out of time", when a rider has finished outside the time limit in a race and is eliminated.
; Hunger knock: Also shortened to "the knock". See hit the wall.
; Hybrid: A bicycle that is a compromise between a road bike and a mountain bike. Often chosen by cyclists for its comfort.

I

; Individual time trial: Race where riders set off at fixed intervals and complete the course against the clock.
; Intermediate sprint: To keep a race or a tour active there may be points along the course where the riders will sprint for time bonuses or other prizes. Also known as the "Traguardo Volante" (TV) in Italian.
; Isolés: A class of independent rider in the Tour de France. Also called a Touriste-Routier or Individuel.

J

; Jump: To aggressively increase speed without warning, hopefully creating a substantial advantage over your opponents. Also (more usually) denoting an attempt to bridge a gap from the peloton or gruppetto to a breakaway. For example: "He is trying to jump across".

K

; Keirin: The keirin is a 2000-meter track event where the riders start the race in a group behind a motorised derny. The derny paces the riders for 1400 meters and then pulls off the track, at which time the cyclists begin a sprint to the finish line. Keirin racing has traditionally been practised in Japan, where it has been a professional sport for over 20 years, and only in which pari-mutuel betting on the riders is permitted.
; Kick: Accelerating quickly with a few pedal strokes in an effort to break away from other riders (e.g. "Contador kicks again to try to rid himself of Rasmussen")
; King of the Mountains (or "KOM"):

# On the ride-tracking web site Strava, usually abbreviated as KOM: The fastest rider on any segment whether uphill, downhill or flat.
; Kit: A group, plus everything else a frameset needs to make a complete bicycle.
; Kite: Is said of a rider who climbs very well but is a poor descender.
; Knock: Referred to as "the knock". Short for "hunger knock". See hit the wall.

L

; Laché: French for "released", see drop.
; Lanterne rouge: French for "red lantern", as found at the end of a railway train, and the name given to the rider placed last in a race.
; Lead out: Sprinting technique often used by the lead out man where the rider will accelerate to maximum speed close to the sprint point with a teammate, the sprinter, drafting behind, hoping to create space between the sprinter and the pack. When the lead out man is exhausted, they will move to the side to allow their teammate to race in the sprint. Often a line of lead out men will be used to form a lead out train to drive the speed higher and higher (and to reduce the chances of other riders attacking) over the closing stages of a race. The purpose of a lead out is for the sprinter to achieve high speed at the sprint approach using as little of their own energy as possible, so they have as much energy as possible for the final sprint.
; Leech: A rider who drafts behind others to reduce their effort, but does not reciprocate. Also wheelsucking.

; Log pile: A TTF (technical trail feature) which consists of a pile of logs designed to be ridden over as a "challenge" or "test" of a rider's skill.

; Lowracer: A short wheel base recumbent bicycle made to be as low to the ground as possible, for less wind resistance.
; LWB: Long wheel base, a recumbent bicycle geometry where the crank is behind the front wheel. Used to be common in the USA.

M

; Madison: A mass-start track event comprising teams of two riders per team. It is similar to a team points race, as points are awarded to the top finishers at the intermediate sprints and for the finishing sprint. Only one of the two team riders is racing on the track at any one time, riding for a number of laps, and then exchanging with their partner by a hand sling. The name comes from the original ''Madison Square Garden'', which was constructed as a velodrome.
; Magic spanner: The situation where a mechanic in a support vehicle will appear to be making adjustments to the bike but in reality they are giving fatigued riders a break by holding onto the car and getting a massive push-off when the commissaires get too close.
;''Maglia Rosa'': Italian for Pink Jersey.
;''Maillot Jaune'': French for Yellow Jersey.
; Mamil: Abbreviation of ''middle-aged men in lycra'', a popular bicycle buying demographic for high-end bicycles.
; Manual: Lifting the front wheel off the ground by the shifting of the rider's weight.
; Mechanical: An issue with the bike, which can result in rider abandoning the race if the issue isn't fixed. When a rider throws/drops his or her chain or has their seatpost loosen they have suffered 'a mechanical'.
; Minute man: The cyclist starting in a time trial either a minute ahead or behind another rider.
; Motor pace: Following a motor vehicle close enough to take advantage of their slip stream.
; MTB: Mountain biking, or a mountain bike.
; Musette:Small lightweight cotton shoulder bag, containing food and drink given to riders in a feed zone during a cycle race. The bag is designed so that it can be easily grabbed by a moving rider. The shoulder strap is placed over the head and one shoulder, the contents are then removed and placed into jersey pockets or bottles (bidons) are placed into bottle cages. The bag is then discarded.
; Muur:Dutch for wall. A short, steep climb. Originates from the Tour of Flanders locations such as Muur van Geraardsbergen and Koppenberg.

N

; Neo-pro: A first year professional.
; Neutral zone: A non-competitive segment of a bicycle race during which competitors have to stay behind the lead vehicles.
; No One Else In The Picture: To win a race solo, without any competitors in view. The "victory pose" shows only the winner.
; Nose wheelie: lifting the rear wheel of the bike using the front brake and shifting the rider's weight forward. A stoppie in motorcycling.

O

; Off The Back: Getting dropped from the group/peloton.
; Omnium: A multi-stage track cycling event whose composition has varied in the past. When reintroduced to the UCI World Championships in 2007, six omnium events have been held, while the European Track Championships have a different set of omnium events.
; On the rivet: A rider who is riding at maximum speed. When riding at maximum power output, a road racer often perches on the front tip of the saddle (seat), where the shell of an old-style leather saddle would be attached to the saddle frame with a rivet.
; On your wheel: The condition of being very close to the rear wheel of the rider ahead of you. Used to inform the rider that you have positioned yourself in their slipstream for optimum drafting.
; OSS: Over seat steering, a steering configuration on recumbent bicycles where the handlebar goes over the seat.
; OTL: Outside time limit, rider failed to finish within a specified time behind the race winner (usually defined as a percentage of the winner's time).
; Over the bars: Unexpected and sudden dismount, either caused by braking too hard with the front wheel or by a road hazard.

P

; Paceline: Group of riders riding at high speed by drafting one another. Riders will take turns at the front to break the wind, then rotate to the back of the line to rest in the draft. Larger group rides will often form double pacelines with two columns of riders. Sometimes referred to as "bit and bit".
; Palmarès: A list of races a rider has won. ( French, meaning list of achievements or list of winners.)

; Panache: Style or courage, displayed for example by breaking away, taking pulls at the front of the group, remounting after a crash or riding while suffering injuries.
; Pannier: A basket, bag, box, or similar container, carried in pairs attached to the frame, handle bars, or on racks attached above the wheels of a bicycle. Panniers are used by commuters and touring cyclists in the same way hikers and campers use backpacks, as a means to pack and carry gear, clothing and other supplies and items. The term derives from the Old French, from Classical Latin, word for ''bread basket.''
; Parcours: The profile of the race or stage route. ( French, course, nm.):
;Pavé: Road made of cobblestones, historically commonplace in Europe and now only seen in classic races such as Paris–Roubaix. ( French, cobblestones).
; Pedaling squares: Riding with considerable fatigue such that the rider is unable to maintain an efficient pedaling form that is strong and smooth.
; Peloton: (from French, literally meaning ''little ball'' or ''platoon'' and also related to the English word ''pellet'') The large main group in a road bicycle race. May also be called the ''field'', ''bunch'', or ''pack''. Riders in a group save energy by riding close ( drafting or slipstreaming) near and, particularly, behind other riders. The reduction in drag is dramatic; in the middle of a well-developed group it can be as much as 40%.
; Pilot: See captain.
; Piranha (piranha’d): (UK) A form of theft that specialises in stealing parts from parked and locked bicycles to the eventual point that very little is left of the bike.
; Pogo: Lifting the front wheel of the bicycle in the air and jumping up and down on the rear wheel while in a stationary position.
; Poursuivant: From French, literally "pursuer". A cyclist or group of cyclists who are separated from and behind the leader(s) ( tête de la course) but in front of the main group. (peloton). This usually occurs when a small number of riders attempt to catch up to the leaders, either to join with them or to "bring them back to the pack" by encouraging the main group to chase them down.
; Prime: Primes (pronounced ''preems'', after the French word for "gift") are intermediate sprints within a race, usually offering a prize or points. Primes are a way to encourage more competitive riding, and also an opportunity for companies to gain publicity by sponsoring a prime. In a criterium, a bell is sounded on the lap preceding the prime sprint at the appropriate line for that prime sprint. The line used for prime sprints need not be the same as the start or finish line. Primes may be either predetermined for certain laps or spontaneously designated under the supervision of the Chief Referee. Lapped riders are not eligible for primes except in the following situation: when a breakaway has lapped the main field, riders in the main field and the breakaway riders are then both eligible for primes.
; Prologue: An individual time trial of usually less than before a stage race, used to determine which rider wears the leader's jersey on the first stage.
; Pull: To take the lead on a paceline or ''echelon''.
; Pump track: A track consisting of rollers and banked turns designed to be ridden without pedalling. Momentum is created by "pumping", movements of the body up and down.
; Puncheur: A type of road bicycle racer who specializes in rolling terrain with short but steep climbs. Ideal races for this type of rider are the one-day classics in spring. These races are characterized by hills that are a 10–20% grade and 1–2 km long; examples include the Liège–Bastogne–Liège, the Mur de Huy in the Flèche Wallonne and the Manayunk Wall in the Philadelphia International Championship. The physique of this type of rider allows them to escape from the peloton through quick bursts usually with the assistance of a teammate. Examples of such racers include Philippe Gilbert, Paolo Bettini, Danilo Di Luca and Peter Sagan, who are able to sprint their way up the shorter climbs to win a stage or a single-day race.Copeland, Tom.

;Queen of the Mountains (or "QOM")
#The title given to the best climber in a cycling road race.
#The fastest female rider on a segment (such as on the ride-tracking web site Strava).
; Q factor (bicycles), Q-factor: The distance between pedal attachment points on a crankset. Ergonomically, affects the distance between a rider's feet.

R

; Randonnée: A ride in the randonneuring discipline of cycling, usually 200–600 km long. Also known as a ''brevet''.
; Randonneuring: A long-distance discipline of cycling where riders attempt courses from 200 to over 1200 km, collecting stamps at controls with the clock running constantly. Every participant finishing within minimum and maximum time limits is considered a winner regardless of finishing order. Riders may ride in a group or solo as they please, and are expected to be self-sufficient between controls. Randonneuring is not regulated by UCI.
; Recumbent: A bicycle or tricycle where the rider is placed in a laid-back position, feet first and sitting in a seat instead of on a saddle. Usually used for ergonomics or aerodynamics. All world land speed records are held by (enclosed) recumbent bicycles, but these bikes are not allowed in races governed by the UCI.
; Rip: To ride fast.
; Rigid: A bicycle without any suspension system.
; Road captain: An experienced rider who organizes a team's riders in a road race, including making tactical decisions and improvising new tactics when pre-race plans are overtaken by events on the road. They are the key link between the directeur sportif and the rest of the team. Road captains are normally selected on a race-by-race basis depending on the demands of the event and their relationship with the team leader. Notable road captains in recent years include Bernhard Eisel, Luca Paolini, Mick Rogers and David Millar.

; Road race: A race on pavement. Longer in distance than criteriums.
; Road rash: Severe skin abrasions caused from sliding on the asphalt in a crash.
; Rock garden: A section found on some mountain biking trails with numerous rocks, designed to challenge a mountain biker's ability to ride over it skillfully.
; Rollers: A type of trainer composed of rolling cylinders under the rear wheel linked to a single rolling cylinder under the front wheel which allow the rider to practice balance while training indoors.
; Rotating weight: Mass that is rotating while the bike is moving, which is a form of inertia. A bicycle wheel can be approximated as a hollow cylinder with most of its mass near the rim. The rotation of the cranks, hubs, and other parts are less significant because both their radius and rotational speed are smaller. Reducing the rotating weight with lighter wheels and tires will permit faster acceleration and braking (or the same acceleration and braking with less energy).
; Rouleur: A rider who is strong on flat and undulating roads. The rider is well suited for races such as Paris–Roubaix and the Tour of Flanders. Tom Boonen and Fabian Cancellara are examples of this.

S

; Saddle: Bike seat.
; Sag: How much a bike sinks into its travel just by having body weight on it.
; Sag wagon: A broom wagon. Probably from the word "sag", i.e. droop, but sometimes explained as an acronym for "support and gear" or "support and grub".; can also come from the French: "soutien au groupe".
; Service course: A command center where bicycles are maintained between races in preparation for the next race. A service course car is a car that carries spare bicycles or wheels in a race should the competing cyclist require a replacement.

; Shifter: A component used by the rider to control the gearing mechanisms and select the desired gear ratio. It is usually connected to the derailleur by a mechanical actuation cable. Electronic shifting systems also exist.
; Singles: Australian English for tubular tyres.
; Singletrack: A mountain bike trail designed for a single line of riders.
; Sit-on and Sit-in: To ride behind another rider without taking a turn on the front (thus tiring the lead rider), often in preparation for an attack or sprint finish. "Sitting in the wheels" is to take an easy ride drafted by the peloton or gruppetto. Often a strategic decision to save energy in races.
; Skinny: A narrow beam to be ridden over lengthwise, as a test of a rider's skill. A skinny can be of various widths (almost as narrow as a bike tire, and up to 20 cm wide) and various lengths (from one to several meters). Some may also "neck-down" to successively thinner widths, and may also have steps, and be on an incline (up or down). They may be close to the ground, or in some cases dangerously high, and even span small creeks or other obstacles.
; Soigneur: French for "healer". A non-riding member of a team whose role is to provide support for the riders, possibly including transportation and organization of supplies, preparation of the team's food, post-ride massages and personal encouragement.
; Sportive bicycle: Also known as ''comfort'' or ''endurance bicycle''. A type of racing bicycle intended for less competitive cyclosportive and long-distance riding. Typically features more upright riding geometry, higher handlebar position, longer wheelbase, and disk brakes.
; Sprinter: Rider with the ability to generate very high power over short periods (a few seconds to a minute) allowing for great finishing speeds, but usually unable to sustain sufficiently high power over long periods to be a good time triallist. Sprinters are usually too big to have a high enough power-to-weight ratio to be good climbers.
; Squirrel: A cyclist who has a tendency to swerve unexpectedly and maintain inconsistent speed. Considered dangerous to follow at close range for the purpose of drafting.
; Stage: One part of a multi-day race, such as the Tour de France.
; Stagiaire: An amateur rider, who is taken in by a professional team during the season. This lets the rider get some experience at riding a few pro races, and the team gets a chance to assess the abilities of the rider.
; Steed: Colloquial name for a bicycle.
; Steerer tube: The part of the fork that is inserted into the head tube of the frame, and is used to attach the fork to the frame using a headset.
; Stem: The component that attaches the handlebars to the steer tube of the bicycle. They come in two major types, quill and threadless. The angle and length plays a major part in how the bicycle fits the rider.
; Sticky bottle: A technique often used by the rider who takes food and water from the team car during a race. The car occupant continues to hold the bottle after handing it to the rider, effectively dragging the athlete. This concerted act gives the cyclist a moment to relax. Usually tolerated by the race ''commissaire'' if the bottle is held for 1–2 seconds, but may result in a sanction (such as disqualification) if abused.
; Stoker: The rider on a tandem bike not steering.
; Summit finish: A race that ends at the top of a mountain climb. Such stages favour the climbers and are normally decisive in major stage races like the Giro d'Italia and the Tour de France.

; Superman: Taking both feet off the pedals and extending them outwards to resemble Superman in flight.
; Swing off: A cyclist fending the air in front of a group of riders, then leaving the front after making their effort by steering their bike to the side is said to "swing off". ''Example:'' "Ivan Basso swings off to let Peter Sagan go!"
; SWB: Short wheel base, a recumbent bicycle geometry where the crank is in front of the front wheel. Comes in many shapes, like highracers and lowracers.

T

; Tandem: A bicycle built for two. Strictly only a bike where the riders are positioned in-line, otherwise it is a sociable.
; Team: A group of cyclists working together as part of a competition.
; Team time trial: Riders start in groups or teams, usually of a fixed size. The time of the ''n''th rider of a team counts for the classification for each team member. In the 2009 edition of Tour de France, riders who are dropped from their team's group would be scored with their own time, instead of the team time.
; Technical: A description of a trail or trail feature requiring "technical" skill to ride well. A technical climb, for example, may have an uneven surface and tight turns making the ascent challenging without well developed mountain biking skills.
; Technical Assistance Zone: A designated section along the course of a mountain bike or cyclocross race along which riders are allowed to accept technical assistance (tools, spare parts, or mechanical work) from another person. In cyclocross racing the technical assistance zone is called the "pit". Not all mountain bike races contain a technical assistance zone, instead requiring riders to carry whatever tools and spare parts they may need. A rider accepting technical assistance outside of the designated zone risks disqualification.

; TTF:''Technical Trail Feature'', a feature often found on mountain biking trails designed as a challenge or test of a rider's skill. It can include log piles, log rides, wall rides, jumps, skinnies, and so forth. Difficult TTFs may have an optional bypass.
; Tempo: Steady pace at the front of a group of riders. A relatively fast tempo can be used by a group or team to control the peloton, often to make up time to a break. The group will ride at the head of the bunch and set a fast enough pace to stretch the peloton out (also known as stringing out) and discourage other riders from attacking. Setting a slower tempo can be done for the purpose of blocking. A tempo is also a type of track race where two points are awarded to the first person to cross the line each lap, and one point is awarded to the second person to cross the line each lap.
; Tempo pace: A level of exertion just below the rider's anaerobic threshold. Used as a reference point in training, this is the highest level of exertion that a given rider can sustain.
; Tête de la course: From French, literally "head of the race". The leading cyclist or group of cyclists, when separated from (in front of) the peloton.
; Tifosi: The word commonly refers to fans along the roadside at professional road cycling races in Italy such as Tirreno–Adriatico, Milan–San Remo, the Giro d'Italia, and the Giro di Lombardia.
; Time trial: A race against the clock where riders are started separately (ranging from 30 seconds to 5 minutes apart). The winner of the race is determined by the fastest person across the course. No drafting may be employed in a time trial as it is a solo race event.
; Time trialist: A rider that can generate relatively high power over long periods of time (5 minutes to an hour or more) in a race against the clock.
; To Stick The Knife In: To finish off a group of riders who are about to crack. The perpetrator knows (or guesses) they have better overall energy than their competitors, presumably after making them suffer with numerous accelerations. The ensuing violent acceleration, which results in dropped competitors, is referred to as "sticking the knife in".
; Track: An oval cycling track for races, banked at up to 50 degrees. Cycling tracks are usually indoors. Bicycling or cycle tracks are also called velodromes. An Olympic track is generally 250m long.
; Train: A method in stage races to get a sprinter to the front of a bunch sprint and launched. The sprinter's team riders will form a line, usually within 5k of the finish, and take turns to build up speed. The last rider in the train will be protected (drafting) until a short distance from the finish. Perfected by HTC and Mark Cavendish.
; Trainer: A piece of equipment that a bicycle stands on so that the rear wheel can spin while the bicycle is stationary, allowing stationary riding. These are usually used when the conditions outside are bad.
; Tricycle: Like a bicycle but with three wheels. Comes in both upright and recumbent versions.
; Trike: See tricycle.
; True sprinter: Also known as an old-school sprinter. A rider who excels primarily in sprint finishes on flat to mildly uphill terrain. Often too heavy to compete in longer or steeper uphill courses.
; Tubular tyres: Tubular tyres have the inner tube permanently stitched inside the casing. They are held in place using glue or glue-tape, and are affixed to rims which lack the sidewalls characteristic of a hook-bead rim. Tubulars take very high pressure which reduces their rolling resistance, and can result in wheelsets that are lower in overall weight than comparable clincher wheels. They can also be ridden at lower pressures than clinchers without the risk of pinch flats, because of the shape of the rim. This makes them well-suited to cyclo-cross, especially in muddy conditions where low tire pressures are used. Also called sew-ups, tubies, or ''tub''.
; Turbo-trainer: A trainer that provided resistance when peddling a bike, fixed in place. Often resistance is provided by a fan assembly or a magnet. See Bicycle trainer.
; Turn: A turn is a rider sharing the workload on a pace line. In a breakaway, the riders expect to share the work equally in "turns". A rider who does not take their turn is said to be "sitting on".

U

; Urban bicycle: Alternatively known as a city bike, a bicycle that is designed to be ridden on the road sometimes utilizing components of a mountain bike and in most cases, hydraulic disc brakes; similar to a hybrid bicycle.
; USS: Under seat steering, a steering configuration on recumbent bicycles where the handlebar goes under the seat, like on an office chair.

V

; Velodrome: A cycling track for races. See ''track''.
; Velomobile: An enclosed recumbent tricycle, usually designed with aerodynamics in mind. Can be fully enclosed or with a head-out configuration.
; Vultures: Race spectators who gather at a technical point of the course where a crash is more likely to occur.

W

; Wall: The edge of the course. See also: hit the wall.

; Wall-ride (or simply "wall"): A banked turn which becomes vertical or nearly vertical (i.e. a "wall"). A skilled rider on a wall at high speed will lean sharply, and in some cases will almost become horizontal while on the wall. A wall-ride can be integral with the trail (formed of dirt or rock), or be constructed of wood.
; Water carrier: Referred to in French as a 'Domestique'. A member of a team who chases down competitors and tries to neutralize their efforts; water carriers will often protect their team leader from the wind by surrounding them. When a leader has to get a repair or stop to answer nature, their domestiques will stay with them and pace them back up to the peloton. Called "water carriers" because they go back to the team car to pick up water bottles for team members. In Italian the term is "gregario".
; Weight weenie: A cyclist who is concerned about the weight of their bicycle or its components.
; Wheelie: Lifting the front wheel of the bicycle in the air through force transmitted through the pedals, and continuing to ride on only the back wheel. The rider maintains the wheelie by applying pedal strokes and rear brake in order to balance the bicycle on only the rear wheel.
; Wheelsucker, wheelsucking: A rider who sits on the rear wheel of others in a group or on another rider, enjoying the draft but not working. Also leech, leeching.
; Winter bike: A racing bicycle adapted for use in winter seasons. Typically these are less expensive and incorporate mudguards, which are rarely present on their modern summer counterparts.
; Wipe out: A crash. Can be used as a verb: "This rider wiped out pretty bad on the wet corner."
; Wide Outside Lane (WOL): An outside lane on a roadway that is wide enough to be safely shared side by side by a bicycle and motor vehicle. The road may be marked with partial lane markings to designate the portion of the lane to be used by bicycles.
; Work: To work is to do "turns on the front", to aid a group of riders by sharing the workload of working against air resistance by "pulling on the front" of the group. Similar to pull. Often used in combination with other expressions: e.g. "He hasn't done any work all day, he has just sat on the breakaway." Working is used in many contexts in the peloton and road racing.

X

Y

; Yellow Jersey: Worn by the rider who is leading in the general classification in the Tour de France; also referred to as the maillot jaune.
Yomp

Derived from Royal Marines slang describing a long-distance loaded march carrying full kit, Yomp is often used in Northern England to describe rides at your own (marching) pace into the Yorkshire Hills.
