AITA PF30 OSBB Campagnolo ceramic bottom bracket converts PF30 OSBB frame (62mm width) to accept Campagnolo Ultra Torque 25mm spindle cranksets. Different from the other's PF30 OSBB bottom bracket plus adapter option, this ceramic bottom bracket is an integrated unit which requires no adapter.

In addition, both sides ceramic bearings are outside of the PF30 OSBB frame which are as same as the Campaganolo Ultra Torque external bottom brackets to give the crank arms the direct support. Hence this system runs much more stable, reliable and performs better.

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.
