Seat Post
A bicycle seatpost, seatpin, saddlepole, saddle pillar, or saddle pin is a tube that extends upwards from the bicycle frame to the saddle. The amount that it extends out of the frame can usually be adjusted, and there is usually a mark that indicates the minimum insertion (or maximum extension). Seatposts can be made of steel, aluminum, titanium, carbon fiber, or aluminum wrapped in carbon fiber. Attachment points Seatposts generally clamp directly onto saddle rails with which they must be compatible, while old or inexpensive seatposts slide into a separate clamp that then clamps the saddle rails. To attach it to the bicycle's main frame, the seatpost is inserted into the seat tube, which must be of a very slightly larger diameter (or a cylindrical shim can be used). The seatpost is held in place by squeezing the top of the seat tube with a tightening ring (temporarily reducing its diameter; a vertical slit cut into the tube allows this to happen without crumpling) until the tu ...

Mountain Bike
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography and application (e.g., steep climbing or fast descending). Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height (an elevated seat position is more effective for pedaling, but poses a hazard in aggressive maneuvers). Mountain bikes are generally specialized for use on mountain trails, single track, fire roads, and othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicycling (magazine)
''Bicycling'' is a cycling magazine published by Hearst in Easton, Pennsylvania. __TOC__ History ''Bicycling'' started in 1961 as ''Northern California Cycling Association Newsletter'', a four-page mimeographed newsletter (8 ½ x 14) started by Peter Hoffman. It covered the local bicycle scene and grew quickly as Vol. 1 No. 6 took on a 5 ½ x8 ½ offset printing format in December, 1961. The name was changed to ''American Cycling Newsletter'' with Vol. 3 No. 1 in March, 1964 issue. The name was changed again with Vol. 5 No. 1 in March, 1965 to ''American Cycling''. The size was changed to a larger format with Vol. 5 No. 1 in March, 1966 to 8 ½ x 11. Peter Hoffman sold the magazine to Leete Publications in August 1968 but stayed on as an editor until late 1969. The last ''American Cycling'' titled magazine was the Nov. 1968 issue, Vol. 7 No. 8. The name was changed to ''Bicycling!'' with the Dec 1968 Issue Vol 7 No 9. For three months following the name change, "American Cyclin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Handlebar
A bicycle handlebar is the steering control for bicycles. It is the equivalent of a tiller for vehicles and vessels, as it is most often directly mechanically linked to a pivoting front wheel via a stem which in turn attaches it to the fork. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for brake levers, shift levers, cyclocomputers, bells, etc. History The dandy horse, or draisienne, invented by Karl Drais and the first vehicle with two wheels arranged in tandem, was controlled by a bar connected to the front steering mechanism and held by the riders' two hands. The first handlebars were solid bars of steel or wood, depending on the manufacturer. Curved, moustache-shaped, drop handlebars became popular in the 1920s. Whatton bars were developed in attempt to improve the safety of penny-farthings. Handlebars made of wood, instead of steel, were used on safety bicyc ...

Trek Bicycle Company
Trek Bicycle Corporation is a bicycle and cycling product manufacturer and distributor under brand names Trek, Electra Bicycle Company, Bontrager, and Diamant Bikes. The company has previously manufactured bikes under the Gary Fisher, LeMond Racing Cycles, Klein, and Villiger Bikes brand names.

In early 1976, with a payroll of five, Trek started manufacturing steel touring frames in Waterloo, Wisconsin, taking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Bicycle
Hybrid bicycles blend characteristics from more specialized road bikes, touring bikes and mountain bikes. The resulting "hybrid" is a general-purpose bike that can tolerate a wide range of riding conditions and applications. Their stability, comfort and ease of use make them popular with novice cyclists, casual riders, commuters, and children. Hybrids typically borrow the flat, straight handlebars and upright seating posture of a mountain bike, which many bicyclists find comfortable and intuitive. Hybrids also employ the lighter weight, thinner wheels and smooth tires of road bikes, allowing for greater speed and less exertion when riding on the road. Hybrid bikes often have places to mount racks and bags for transporting belongings, much like a touring bike. Hybrid bikes have spawned numerous sub-categories satisfying diverse ridership. They are classified by their design priorities, such as those optimized for comfort or fitness — and those offered as city, cross or commu ...

Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elastomer
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of ''elastic polymer'', is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually a compound of several elements among carbon, hydrogen, oxygen and silicon. Elastomers are amorphous polymers maintained above their glass transition temperature, so that considerable molecular reconformation is feasible without breaking of covalent bonds. At ambient temperatures, such rubbers are thus relatively compliant ( E ≈ 3 M Pa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, soles for shoes, and damping and ...

Spring (device)
A spring is an elastic object that stores mechanical energy. In everyday use the term often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel, although some non-metallic objects like the bow are also springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. An extension or compression spring's rate is expressed in units of force divided by distance, for example or N/m or lbf/in. A torsion spring is a spring that works by twisting; when it is twisted about its axis by an angle, it produces a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
