some one who know the BBright?
I search the web,the answer is
BBright™ (bicyclestoparts)is the only Bottom Bracket standard that uses an oversize 30mm axle and allows for oversized frame tubes (up to 16% wider than standard bottom brackets).
It offers the optimal combination of stiffness and weight for the overall system (crankset and frame together).
But I still don't understand. BBright just wide than the BB30?
or is better than BB30?
