TruVativ's AKA cranks are all mountain ready with burly hollow-forged arms and a stout BB30 axle. The bottom bracket comes ready for action, too, with Gutter Seal technology to keep grime where it belongs—outside of the bearings. Clean rides or dirty, the chainrings are machined for crisp shifting and low weight and TruVativ's GXP bottom bracket will provide years of smooth-spinning service.
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.
Weight: 890 grams (crankset and bottom bracket)
