AITA BB30 Shimano Road ceramic bottom bracket converts BB30 frame to work with a Shimano/FSA 24mm spindle road 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 moved out from the BB30 frame and extend the supporting width from 68mm to 90mm which are as same as the Shimano/FSA external bottom brackets. Hence with this direct support the conversion bottom bracket 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 only consume 20% of the power compared with the steel bearing, plus the bearings will last 3-5 times longer.

Unique designed dust cover improves the durability of the bottom bracket compared with the traditional Shimano’s design.
