Cranks and bottom brackets have a decisive influence on the overall functional performance of a bicycle. Clean running, good power conversion and high resilience are essential factors when choosing a crankset. Shimano produces a large range of different cranksets and matching bottom brackets. This means that an optimally suitable system is available for every bike and every discipline. Hollowtech II works with 24 mm axles and bearings. After analyzing all factors and carrying out tests, we decided on axles and bearings with a 24 mm diameter. This offers the greatest possible balance of rotational efficiency, stiffness, resilience, tightness and weight in proven Shimano quality. ”
