AITA PF30 road ceramic bottom bracket is fully compatible with PF30 (68/73mm width) standard frame. It is a pressfit bottom bracket to fit PF30 standard frames with 30mm spindle cranks (30mm cranks must meet the frame width requirement). This PF30 road 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 only consume 20% of the power compared with the steel bearing, plus the bearings will last 3-5 times longer.
