Bicycle chain. 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.
Simplified diagram of gear inches: As the rear sprocket is halfed in size, the distance traveled by the rear wheel doubles, at half the torque. Gear inches is an imperial measure corresponding to the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent ( direct-drive) gearing. A commonly used metric alternative is ...
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
Crankset. The crankset (in the US) or chainset (in the UK) is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel.
A bicycle gearbox with chain tensioner. 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 ...
Mechanical advantage in different gears of a bicycle. Typical forces applied to the bicycle pedal and to the ground are shown, as are corresponding distances moved by the pedal and rotated by the wheel. Note that even in low gear the MA of a bicycle is less than 1. Consider the 18-speed bicycle with 7 in (radius) cranks and 26 in (diameter) wheels.
Brown maintained Sheldon Brown's Bicycle Technical Info, a web site highlighting a broad range of cycling subjects ranging from how to fix a bicycle flat tire to details on Raleigh and English three-speed bicycles, [9] Sturmey-Archer hubs, [10] tandems, [11] and fixed-gear bicycles. [12] He repaired cameras and was an amateur photographer.
Chainline. The chainline is the angle of a bicycle chain relative to the centerline of the bicycle frame. [ 1] A bicycle is said to have a perfect chainline if the chain is parallel to the centerline of the frame, which means that the rear sprocket is directly behind the front chainring. [ 1] Chainline can also refer to the distance between a ...
