It’s lighter! By eliminating the BB cups and using a
larger diameter alloy spindle, crank and BB weight
can be reduced by up to 12%. It’s narrower! With the
bearings inside the BB shell, crank width is reduced,
increasing ankle clearance. It’s stiffer! increasing
spindle diameter increases crankset stiiffness. It’s
more durable! BB30 bearings are larger than conventional or external BB bearings, yielding longer
bearing life. |
