AITA BB30 Campagnolo ceramic bottom bracket converts BB30 frame to fit Campagnolo Ultra Torque 25mm spindle cranksets. Different from the other's BB30 bottom bracket plus adapter option, this ceramic bottom bracket is an integrated unit which requires no adapter or spacers.

In addition, both sides ceramic bearings are outside of the BB30 frame which are as same as the Ultra Torque external bottom brackets 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.
