Crankset SummaryThe crankset 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, which in turn drives the rear
wheel. It consists of one or more chainrings attached to the crankarms, which attach the
pedals to the crank. 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.
Over the years, many different strategies have propelled crankset development, not the least of which have been the addition of new
bottom bracket technologies, the desire for an increased amount of mechanical advantage, and weight savings.
When evaluating cranksets be mindful of weight differences, construction differences (better cranksets are stiffer, and have less play in them), and gearing differences.
