AITA EVO386 Shimano road ceramic bottom bracket converts EVO386 frame to accept Shimano/FSA 24mm spindle cranksets.

This conversion bottom bracket in an integrated unit to allow a Shimano/FSA 24mm crankset run on a EVO386 frame without any additional adapters or spacers.

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.

2 year warranty.
