This EVO386 ceramic bottom bracket comes 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 consume 20% of the power compared with the steel bearing, plus the bearings will last 3-5 times longer.
