A bicycle crankset consists of three main components: the crank arms, chainrings, and bottom bracket. The crank arms are attached to the pedals and rotate to propel the bike forward. The chainrings are connected to the crank arms and transfer power from the pedals to the chain. The bottom bracket connects the crankset to the bike frame and allows the crankset to rotate smoothly. Together, these components work in harmony to convert the rider's pedaling motion into forward movement, providing power and efficiency while cycling.
