It features a hollow axle made of chromoly steel, which provides excellent stiffness and enables maximum power transfer while pedaling. The integrated ball bearings are optimally sealed and protected from dirt and water by new external seals, enhancing the longevity and reliability of the bottom bracket. The cold-forged aluminum shells contribute to stability and ensure a precise fit. This bottom bracket is not only functional but also an essential component for your bike's performance, especially regarding power transfer efficiency.
