BBright SRAM GXP Ceramic Bottom Bracket
AITA BBright SRAM ceramic bottom bracket converts BBright frame to accept SRAM GXP 22-24mm spindle cranksets. Different from the other's PF30 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 BBright frame which are as same as the SRAM GXP 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 only consumes 20% of the power compared with the steel bearings, plus the bearings will last 3-5 times longer.
