Features and Information
BB30 is an oversize bottom bracket standard that boosts stiffness and decreases weight. BB30 bottom bracket bearings are pressed directly into compatible frames, meaning there are no heavy external cups to thread in. And, BB30 cranksets feature 30mm-diameter spindles (standard spindles are smaller) for greater pedaling efficiency and increased power transfer.
