Bicycle chains Roller chain and sprocket. A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it.Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues. A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for
A small section of KMC bicycle chain.

[2] They make cam driving chains, balance driving chains, oil pump chains, motorcycle chains, and industrial chains. [3]
Chain: a system of interlinking pins, plates and rollers that transmits power from the front sprocket(s) to the rear sprocket(s) Chainguard: Gear case cover for the entire chain either totally encasing (sometimes containing oil) or 'incomplete'. Either way, designed to keep clothing from fouling the chain.
Chain drive was the main feature which differentiated the safety bicycle introduced in 1885, with its two equal-sized wheels, from the direct-drive penny-farthing or "high wheeler" type of bicycle. The popularity of the chain-driven safety bicycle brought about the demise of the penny-farthing, and is still a basic feature of bicycle design today.
Bicycle chain, type of roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it. The chain is made up of a number of rigid links that are hinged together by pin joints to provide the flexibility needed to wrap around the bicycle's gears.
Skip-link chain is an obsolete roller chain for bicycles in which side plates are alternately short and long, and so rollers are alternately close together and far apart. A skip-link chain running over the rear sprocket on a bicycle. In bicycle chains, skip-link chain has the same one-inch spacing as the earlier block chain. Due to the ...
In the case of bicycle chains, it is possible to modify the overall gear ratio of the chain drive by varying the diameter (and therefore, the tooth count) of the sprockets on each side of the chain. This is the basis of derailleur gears. A multi-speed bicycle, by providing two or three different-sized driving sprockets and up to 12 (as of 2018 ...
