Availability: Out of stock

BB386 is most simply thought of as a 86.5mm wide PF30 bottom bracket shell. The BB386's width places the bearings further apart than both BB30 and PF30. It's designed to match the bearing width of English external bottom brackets. The HSC BB386 bottom bracket features a CNC machined high density delrin shell protecting your frame while pressing your bearings and preventing any creaking. The bearings are HSC's exceptionally durable and fast Si3N4 ceramic bearings with steel races. With the quality of the bottom bracket and its price it makes a high quality replacement or component upgrade saving both weight and lowering resistance over most stock bottom brackets.
