Gravel riding demands more from your bottom bracket — rain, mud, creek crossings, and washboard roads. Our PF30 Gravel BB uses the same Grade 3 silicon nitride ceramic bearings and DLC-coated races as our road version, but with heavy-duty labyrinth seals and our all-weather grease formulation. The wider 46mm PF30 shell provides excellent lateral stiffness for out-of-saddle climbing on loose terrain. Built to last entire gravel seasons without service.
