AITA BSA Campagnolo ceramic bottom bracket is fully compatible with Campagnolo Ultra Torque 25mm cranks. It is an English thread bottom bracket with AITA signature hybrid ceramic bearings built up with Grade 3 Si3N4 ceramic balls and ABEC7 hardened steel races.

With the Grade 3 Si3N4 ceramic balls (8 times rounder and 4 times smoother than the steel's), spinning on the hardened ABEC 7 races, AITA's ceramic bearings run much smoother than most of the bearings in the market and will save you watts in each racing, plus the bearings will last 3-5 times longer than the steel bearings.
