Wider is better with the e*thirteen BB30 bottom bracket. Our threaded BB30 bottom bracket adapts all cranks with 30mm spindle to frames running BB30 BB shells (42mm bore diameter).

The BB30 bottom bracket spaces the bearings nice and wide outside the BB shell for maximum stiffness and a threaded centre tube keeps bearings properly aligned for longer life. Custom seals, grease fill and bearings are designed from the ground up for top-notch durability and smooth spinning.
