To keep this bottom bracket running smoothly even after a wet day on the road, we also use high quality seals to keep out the water. Since the bearings sit directly on the frame, we take care to carefully machine the cups so they fit perfectly. The bearings themselves sit directly on the crank axle to help to decrease premature wear. This bottom bracket has a choice of our Premium bearings or stainless steel SPB (Sapporo Precision Bearing) bearings.

This bottom bracket is a great solution for riders looking for a long-lasting bottom bracket that fits a BB86 frame but who uses cranks with 30 mm axles.
