Shimano Hollowtech II

Shimano Hollowtech II is a widely used bicycle crankset and bottom bracket standard. It integrates the bottom bracket axle (spindle) directly into the drive-side crank arm, featuring hollow-forged crank arms. This design maximizes power transfer by reducing weight and increasing structural stiffness.
