Optimise your gravel bike to the BB386 46x86.5 standard with a specific bottom bracket that allows you to mount a Campagnolo crankset with an Ultra Torque axle. Designed for demanding off-road conditions, ProTech technology adds an external seal to protect the ball bearings from moisture and anything else that could impair the smooth running and lifespan of the bottom bracket. Performance is guaranteed thanks to increased rigidity, improved rolling efficiency and maximum resistance thanks to the oversized bearings placed on the outside of the cups.
Please note that this bottom bracket is sold without bearings.
