Cannondale OPI Spidering SL

The original SpideRing. Featuring a 3D-forged, 10-arm design and obsessive weight-saving machining throughout, this spider / ring combo is the best shifting ultralight chainring set on the market. Available in 53/39, 52/36 and 50/34 chainring combinations.

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.
