Bottom brackets are an essential part of the bike that is often overlooked and forgotten, but we saw the bottom bracket as another opportunity to improve performance and efficiency.For our BB, we developed a seal that achieves a very low level of drag while maintaining excellent protective qualities. Its thinner, low-viscosity bearing grease with the correct fill level provides greater durability at high speeds. If you use the best crankset on the market, you need the performance crankset to go with it.Details Bearing type : Steel. PressFit bottom bracket. Case diameter: 46 mm. Axle diameter: 30 mm. Thinner and less viscous bearing grease for better durability at high speed. Case width: 79 mm. Internal test procedure includes the development of a 24-hour continuous water invasion test. Weight: 91 g.
