The Shimano BB-RS501 bottom bracket allows you to install a crankset with a 24 mm axle into a road bike frame with threaded bearing. Depending on the version, it is a BSA or ITA bottom bracket shell with 68 mm or 70 mm width. Shimano recommends BB-RS501 for the cranksets of the Tiagra, Sora, Claris, Alfine, GRX RX600 series and for a number of no-group models. It features an optimised seal design that extends durability. The bearings are made of steel, the bearing cups of anodised aluminium. In combination with a corresponding crankset, this bottom bracket and its Hollowtech II technology ensures stability and efficiency with every pedal rotation.

Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
