Bottle Cage
A bottle cage is device used to affix a water bottle to a bicycle. Composed of plastic, aluminum, stainless steel, titanium or carbon fiber, it is attached to the main frame of a bicycle, the handlebars, behind the saddle, or, in uncommon cases, the fork. Most modern bicycles have threaded holes in the frame to hold the bottle cage, often called braze-ons even though they may be welded, glued, riveted, or moulded into the frame material. Clamps are necessary on bicycles not so equipped, such as older or less expensive models. Locations The most common location for a frame-mounted bottle cage is on the top side of the downtube. The most common location for a second frame-mounted bottle cage is on the front side of the seat tube. Small bikes and mountain bikes with rear suspension often do not have enough room for two bottle cages inside the main frame triangle. Some mountain bikes have highly sloped top tubes that limit the size of bottles mounted inside the triangle. Some tou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional w ...

Bottle Sling
The bottle sling (also called a jug sling, a Hackamore knot, or a Scoutcraft knot) is a knot which can be used to create a handle for a glass or ceramic container with a slippery narrow neck, as long as the neck widens slightly near the top. While classed with binding knots, such as the reef knot and miller's knot, the bottle sling is able to perform a function for which most other binding knots are unsuited. The bottle sling's specific form allows it to grip a cylinder, assuming it has even a slight flare or collar, and lift it along its axis when the knot is loaded by all four strands. With appropriate size cord, most wine bottles can be reliably suspended with this knot. History The bottle sling was described in detail by the Greek physician Heraklas in his first century monograph on surgical knots and slings. It was included under the name ''diplous karkhesios brokhos'' ("double jug-sling noose"). Clearly familiar with the knot, Heraklas provided three distinct tying m ...

Bicycle Seat
A bicycle seat, unlike a bicycle saddle, is designed to support the rider's buttocks and back, usually in a semi-reclined position. Arthur Garford is credited with inventing the padded bicycle seat in 1892, and they are now usually found on recumbent bicycles. Bicycle seats come in three main styles; mesh, hardshell and combination Seat types Mesh A typical mesh seat consists of a metal frame with mesh stretched over it and secured with adjustable straps, zip ties, string or shock cord. Hardshell Hardshell seats are normally made of a composite material such as GRP or carbon fibre although metal and wood versions do exist. A hardshell seat is normally covered with some-form of padding, this is usually closed or open cell foam although some extreme racing machines do not have any padding on the seat to reduce weight and increase efficiency. Hardshell seats are generally used at more reclined angles than mesh seats. Some riders complain of excessive road noise vibrating throug ...

Touring Bicycle
A touring bicycle is a bicycle designed or modified to handle bicycle touring. To make the bikes sufficiently robust, comfortable and capable of carrying heavy loads, special features may include a long wheelbase (for ride comfort and to avoid pedal-to-luggage conflicts), frame materials that favor flexibility over rigidity (for ride comfort—though frame flexing can eventually lead to metal fatigue and frame failure, so newer frames are rigid), heavy duty wheels (for load capacity), and multiple mounting points (for luggage racks, fenders, and bottle cages). Types Touring bicycle configurations are highly variable and may include road, sport touring, trail, recumbent, or tandem configurations. Road touring Road touring bicycles have a frame geometry designed to provide a comfortable ride and stable, predictable handling when laden with baggage, provisions for the attachment of fenders and mounting points for carrier racks and panniers. Modern road tourers may employ 700C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tour De France
The Tour de France () is an annual men's multiple-stage bicycle race primarily held in France, while also occasionally passing through nearby countries. Like the other Grand Tours (the Giro d'Italia and the Vuelta a España), it consists of 21 stages, each a day long, over the course of 23 days, coinciding with the Bastille Day holiday. It is the oldest of the Grand Tours and generally considered the most prestigious. The race was first organized in 1903 to increase sales for the newspaper '' L'Auto'' and is currently run by the Amaury Sport Organisation. The race has been held annually since its first edition in 1903 except when it was stopped for the two World Wars. As the Tour gained prominence and popularity, the race was lengthened and its reach began to extend around the globe. Participation expanded from a primarily French field as more riders from all over the world began to participate in the race each year. The Tour is a UCI World Tour event, which means that th ...

Bicycle Pump
A bicycle pump is a type of positive-displacement air pump specifically designed for inflating bicycle tires. It has a connection or adapter for use with one or both of the two most common types of valves used on bicycles, Schrader or Presta. A third type of valve called the Dunlop (or Woods) valve exists, but tubes with these valves can be filled using a Presta pump. Several basic types are available: * Floor pumps * Frame-mounted * Compact or mini * Foot-operated * Double-action * Blast or tubeless In its most basic form, a bicycle pump functions via a hand-operated piston. During up-stroke, this piston draws air through a one-way valve into the pump from outside. During down-stroke, the piston then displaces air from the pump into the bicycle tire. Most floor pumps, also commonly called track pumps, have a built-in pressure gauge to indicate tire pressure. Electrically-operated pumps intended to inflate car tires (as available in most service stations) can in prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Lighting
Bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination. A secondary purpose is to illuminate reflective materials such as cat's eyes and traffic signs. A third purpose may be to illuminate the roadway so that the rider can see the way ahead. Serving the latter purposes require much more luminous flux and thus more power. Many jurisdictions require one or more bicycle lights to be fitted to bicycles ridden at night — generally a white light in the front and a red light at the back, like with other vehicles. History Fire The earliest bicycle lamps were oil-fueled and started to be manufactured in 1876 for the Ordinary (High-Bicycle) and solid-tired tricycles. From 1896, acetylene gas lighting for bicycles started to be introduced and later in 1899, acetylene gas lamps for the motor-car became popular. ...

Recumbent Bicycle
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Most recumbent riders choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by back and buttocks. On a traditional upright bicycle, the body weight rests entirely on a small portion of the Tuberosity of the ischium, sitting bones, the feet, and the hands. Most recumbent models also have an aerodynamics, aerodynamic advantage; the reclined, legs-forward position of the rider's body presents a smaller frontal profile. A recumbent holds the world speed record for a bicycle, and they were banned from racing under the Union Cycliste Internationale (UCI) in 1934, and now race under the banner of the World Human Powered Vehicle Association (WHPVA) and International Human Powered Vehicle Association (IHPVA). Recumbents are available in a wide range of configurations, including: long to short wheelbase; large, small, or a mix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem Bicycle
A tandem bicycle or twin is a form of bicycle (occasionally a tricycle) designed to be ridden by more than one person. The term tandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders. Patents related to tandem bicycles date from the mid 1880s. Tandems can reach higher speeds than the same riders on single bicycles, and tandem bicycle racing exists. As with bicycles for single riders, there are many variations that have been developed over the years. Terminology The term tandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders. A bike with two riders side by side is called a sociable. Tandem bicycles are sometimes called "Daisy Bells". This is in reference to "Daisy Bell (Bicycle Built for Two)" which is a popular song, written in 1892 by British songwriter Harry Dacre, with the well-known chorus, "Daisy, Daisy / Give me your answer, do. / I'm half crazy / all for the love of you", ending wi ...
