The Shimano BB-R9100 bottom bracket was specially designed for Dura-Ace 11-speed cranks. It features small ball bearings to minimize weight and works with Hollowtech II technology for more stability and rotational efficiency. We offer the BB-R9100 in the version for ITA (Italian) threads. Shimano Hollowtech II is a crank bottom bracket system designed for 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 an axle or crank arm. Bearing diameter of 24 mm, which has proven to be optimal in terms of stability. In many cases, the bearing shells are on the outside so that the load is better distributed. In addition, there are high-quality precision seals that ensure a long service life. Compati.
