List of bicycle parts by alphabetic order: Axle : as in the generic definition, a rod that serves to attach a wheel to a bicycle and provides support for bearings on which the wheel rotates. Also sometimes used to describe suspension components, for example a swing arm pivot axle
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios .
A person pedalling with 100 W power can achieve 5.5 m/s on a roadster, 7.5 m/s on a racing bicycle, 10 m/s with a faired HPV and 14 m/s with an ultimate HPV. [9] In competitive cycling a sustainable high speed is augmented by the use of light materials, low-resistance tires, aerodynamic design, and the aerodynamic effects of the peloton. The ...
The NuVinci CVT system has a small number of parts. [5] [6] Most CVTs have lower mechanical efficiency than competitive conventional transmissions.Since any CVT may allow a power plant, human or motorized, to operate at (or closer to) its speed of optimal efficiency, output torque or output power, the NuVinci CVT may improve a system's overall efficiency or performance compared to a ...
Shimano STI Dual Control shifter and brake lever: 1. Main lever 2. Release lever A. Pulling the main lever towards the rider applies the brake B. Pushing the main lever towards the center of the bike downshifts one, two or three gears depending on how far the lever is pushed (right hand shifter) or changes from a small chainring to a larger chainring (left hand shifter)
The Schwinn Racer was a bicycle in the lightweight series of bikes built by Schwinn Bicycle Company in Chicago from 1957 to the mid-1970s. They had a Sturmey Archer 3 speed with 26 x 1 3/8 tires as well as the occasional 24x1 3/8. They were sold with both S5 (Deluxe Racer) and S6 (Standard Racer) designated rims.
The width of early Shimano 6- and 7-speed cassettes was 36 mm, and early 8-speed 40 mm wide. Shimano then changed again and standardised 8-11 speed cassettes on 41.5 mm and second generation 7-speed to 38 mm. The widening of the sprocket carrier on the cassette hubs to 41.5 mm resulted in a decrease in the distance between the hub flanges.
One example is the Protean two-speed derailleur available on the Whippet safety bicycle. [4] The French bicycle tourist, writer and cycling promoter Paul de Vivie (1853–1930), who wrote under the name Vélocio , invented a two speed rear derailleur in 1905 which he used on forays into the Alps .
