Chainring: (one of the) front gear(s), attached to a crank; Chainset: see Crankset; Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends; Chain tensioner: a device to maintain proper chain tension; Chaintug: a device to aid in setting the proper chain tension
Bottom bracket wrench for newer bottom bracket styles Crank extractor. A chain tool or chain splitter is used to 'break' a chain, in order to remove it from a bike or remove links, or to put a chain back together. A crank extractor is used to pull the crank off the bottom bracket spindle. A pedal wrench removes the pedals from the bicycle. It ...
Simple platform bicycle pedal. The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or shoe and the crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels.
Note that if a normal right-side-drive crankset is installed backwards to create a left-side-drive bicycle, the threaded pedal holes at the end of the crank arms would be reversed. In this configuration, precession may loosen the pedals over time, causing the pedals to become detached and/or damaging the pedal threading in the crank arms. A ...
A disadvantage is that assembly and disassembly of press-fit bottom bracket bearings require expensive special equipment. [12] [13] [14] Some hobby-mechanics assemble and disassemble themselves using simple hand-tools, but there is a certain risk that the frame may become damaged. Another disadvantage is that many users report that they start ...
Dynamic Runabout 7 shaft-driven bicycle Drive-shaft housing. A shaft-driven bicycle is a bicycle that uses a drive shaft instead of a chain to transmit power from the pedals to the wheel. Shaft drives were introduced in the 1880s, but were mostly supplanted by chain-driven bicycles due to the gear ranges possible with sprockets and derailleurs ...
Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is fixed , but most modern bicycles have multiple gears and thus multiple gear ratios.
Some historians who have studied the invention of the pedal-driven bicycle, including David V. Herlihy, state that Macmillan was not the first inventor.Herlihy states there is no contemporary documentary evidence that a pedal-crank design was applied to a 2-wheeled vehicle and that letters from customers in Scotland to the Michaux company in 1868 state that all of the human-powered vehicles ...
