BB30 is lighter, narrower, stiffer and more durable than traditional bottom bracket systems. Oversized alloy spindles and bearings pressed directly into the BB shell offer weight savings up to 12%.
Hollow Forged crankarms result in superior strength and stiffness and a higher strength-to-weight ratio compared to solid arms. We offer a range of Hollow Forged cranksets from road to XC to heavy-duty Gravity products.
