Because of oversized bearings which are pressed directly into the bottom bracket shell the KCNC Press Fit BB30 bottom bracket is extremely stiff and offers weight savings. In combination with a crankset with 30 mm spindle new standards for stiffness to weight ratio will be reached. Advantages of the new system are: - lighter - stiffer - low Q-factor (narrower cranks, increasing ankle clearance) - more durable because of significantly larger bearings results in longer bearing life.
Note: This bottom bracket is only compatible with bicycle frames and cranks constructed for the Pressfit 30 bottom bracket standard.
