Shimano Dura Ace SM-BB92 Press Fit Bottom Bracket

A large diameter and low weight make the Shimano BB86 press fit bottom bracket durable so you can get more out of your bike.

The Shimano BB86 press fit bottom bracket is a Dura Ace/XTR level component for frames with 86.5 x41 mm fitment. It is suitable for a frame with either a  BB86 Road or BB92 MTB bottom bracket shell.

The design of this bottom bracket is characterised by low weight and low Q-factor while the larger diameter bearing gives greater durability.
