Derailleur Hanger
A fork end, fork-end, or forkend is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end that allows the rear wheel to be removed without first derailing the chain. Track bicycle frames have track fork ends, on which the opening faces rearwards. Because they do not have dropouts, the chain must be derailed from the sprocket before the rear wheel can be removed from a typical track bike. Some single-speed bicycles intended for street or trail use are also equipped with track fork ends instead of dropouts. On bicycles that do not have a derailleur or other chain tensioning device, rear ''horizontal dropouts'' allow adjustment of chain tension, and can accommodate a range of chain lengths or cog sizes. They were standard on most older derailleur bicycles from before the 1990s. An older derailleur-equipped bicycle with horizontal dropouts can be readily converted into singlespeed, fixed gear or to use an internally ...

Derailleur
Shimano 600 front derailleur (1980) A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another. Modern front and rear derailleurs typically consist of a moveable chain-guide that is operated remotely by a Bowden cable attached to a shifter mounted on the down tube, handlebar stem, or handlebar. When a rider operates the lever while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets. Etymology ''Dérailleur'' is a French word, derived from the derailment of a train from its tracks. Its first recorded use was 1930. History A modern road bicycle drivetrain with front and rear derailleurs Various derailleur systems were designed and built in the late 19th century. One example is the Protean two-speed derailleur available on the Whippet safety bicycle. The French bicycle tou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Howard (cyclist)
John Howard (born August 16, 1947 in Springfield, Missouri) is an Olympic cyclist from the United States, who set a land speed record of 152.2 miles per hour (245 km/h) while motor-pacing on a pedal bicycle on July 20, 1985 on Utah's Bonneville Salt Flats. This record was beaten in 1995 by Fred Rompelberg. A competitor at the 1968, 1972, and 1976 Summer Olympics, Howard won the gold medal in the 1971 Pan American Games road cycling race in Cali, Colombia, as a member of the U.S. Army cycling team by beating Luis Carlos Florez in a sprint finish. He is a former 4-time U.S. National Road Cycling champion (1968, 1972, 1973 and 1975) and won the 1981 Ironman Triathlon World Championship in Hawaii. Howard won the first two editions of the Red Zinger Bicycle Classic stage race in Colorado in 1975 and 1976. In 1982, Howard was one of four competitors in the inaugural Race Across America RAAM, eventually finishing second. In 1989, John Howard appeared in an instructional vid ...

Shear Pin
{{unreferenced, date=September 2018 A shear pin is a mechanical detail designed to allow a specific outcome to occur once a predetermined force is applied. It can either function as a safeguard designed to break to protect other parts, or as a conditional operator that will not allow a mechanical device to operate until the correct force is applied. Shear pins as safeguards In the role of a mechanical safeguard, a shear pin is a safety device designed to shear in the case of a mechanical overload, preventing other, more expensive or less-easily replaced parts from being damaged. As a mechanical sacrificial part, it is analogous to an electric fuse. They are most commonly used in drive trains, such as a snow blower's auger or the propellers attached to marine engines. Another use is in pushback bars used for large aircraft. In this device, shear pins are frequently used to connect the "head" of the towbar – the portion that attaches to the aircraft – to the main shaft of t ...

Bicycle Frame
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the ''diamond frame''. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post. Frame builders will often produce the frame and fork together as a paired set. Variations Besides the ubiquitous diamond frame, many different frame types have been developed for the bicycle, several of which are still in common use today. Diamond In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube and seat tube. The rear triangle consists of the seat tube joined by p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Luggage Carrier
A luggage carrier, also commonly called a rack, is a device attached to a bicycle to which cargo or panniers can be attached. This is popular with utility bicycles and touring bicycles. Bicycle luggage carriers may be mounted on the front or rear of a bicycle. The rear mount is more common. Racks on the front are mostly reserved for utility and cargo bikes. A special type of front rack is a low rider which is mainly used for bicycle touring. The term luggage carrier can also refer to a device with two wheels used to wheel luggage or something of similar weight from one place to another, similar to a dolly (hand truck) but lighter and usually able to be folded up. Mounting Bicycles may have eyelets, tapped with a standard thread, at the dropouts on the rear chainstays, and on the front fork blades. Mounting a bike rack is possible without these eyelets, but requires additional hardware. A style of rack clamps only to the seatpost, does not require eyelets or additional hard ...
