Technologies:
• BB30: SRAM RED & SRAM Force cranks have a SUPERSIZED option with BB30, a new industrial standard for bottom brackets. BB30 is stiffer than standard bottom brackets – delivering more power to the pedal, nearly 20% lighter – for flying up the hills, and offers substantially more ankle clearance – no more discomfort while riding. (The Bottom Bracket bearings are NOT included, but have to be purchased separately in the correct size)
• OCT: To fabricate our Open Core Technology a single mass of premium alloy is pushed, pulled and squeezed into a hollow crank arm. During our exclusive process the magic happens, producing supreme strength while remaining weight-conscious. We may have not been the first to fabricate hollow crank arms, but we are the best by yielding the highest stiffness-to-weight ratio out there. Our OCT cranks are stiffer, stronger, and lightweight beyond any solid forged crankset and when we use our AL-7050-TV to fabricate with OCT the results are impressive.
