2. Abstract:

The crankset (in the US) or chain set (in the UK), is the component of a bicycle drive train that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain, which in turn drives the rear wheel.

It consists of one or more sprockets, also called chainrings or chain wheels attached to the cranks, arms, or crankarms to which the pedals attach.

It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain.
