SRAM Rival OCT Crankset
The SRAM Rival Open Core Technology (OCT) Crankset shows the way forward for any serious cyclist, putting power to the road while saving weight at the same time. Open Core Technology means the crank arms are hollow-forged out of AL-6066 alloy for maximum strength and mount our PowerGlideTM 10 speed chainrings.
- OCT construction is stronger and lighter than standard solid-core alloy cranks.
- PowerGlide chainrings are competition proven with long-lasting finishes.

GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.
- OCT (Open Core Technology)™
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.
- Pressfit 30™
This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching.
