As beautiful as the cranks are, the most eye-catching feature of the cranks are the OPI SpideRings. Inspired by auto racing wheels, these one-piece spider and rings are 3D forged and machined from a single block of aluminum. This one-piece design saves weight and reduces chainring deflection for crisper, more precise shifts. SpideRings are available in many different configurations and are retrofittable to all HOLLOWGRAM CRANKS.
Our patented OPI 3D forging process enables us to build hollow, seamless crankarms that are not only extremely light but also incredibly strong and stiff. In fact, they are the stiffest, strongest crankarms we've ever made. Lighter and stiffer than Dura Ace and completely compatible with every HollowGram spider and chainring set-up, the HollowGram Si cranks bring top-level performance to more pricepoints.
