Hollow forged crankarms result in
superior strength and stiffness and a higher strength-to-weight ratio
compared to solid arms. The 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%.Please note: this crankset will only fit frames specifically built to the BB30 (new, not standard) spec.
