Description

There are several BB standards to choose from – for Niner dedicated geared only race bike they like PF*0. It’s compatible with any BB*0 crankset (as well as standard threaded BB systems, with an adapter) and the bearing cups are delightfully easy to install. The oversized *0mm spindle is light and resists the torque of even the mightiest Ninerds. Oversized bearings spin longer and smoother between overhauls. The plastic cups of the PF*0 BB system don’t require a machined aluminum bottom bracket shell insert, allowing a minimalist carbon construction.
