A crankset is a vital component of how a bicycle functions. It consists of the bottom bracket, the two crank arms, and potentially several chainrings. The crankset facilitates the transfer of power from the rider’s pedaling down through the bike chain that propels the bicycle forward. The crank arms bridge the pedals and the bottom bracket, while the chainrings provide the means for the rider to shift gears for varying surfaces. The crankset must provide efficient pedaling and utilize power well for both bicycle racing as well as recreational bicycle riding.
