The crankset is the main power transmission part of the bicycle's drivetrain, consisting of the crank (swing arm) and chainring, which converts kinetic energy from the cyclist's legs into the force pulling the chain and rear wheel to move the bike. The crank is directly connected to the pedals and is located at the center axis, playing an important role in optimizing performance and riding feel.
