The artfully designed SpideRing 10 Arm Chainring improves shifting performance with a forged one-piece construction that both reduces weight and increases stiffness. It's made for speeding across the flats and for shifting performance on intense climbs, and its eye-catching design is a bonus for our ride. Cannondale's one-piece integration of spider and chainring reduces the number of parts and, in turn, increases durability and performance with a simpler system.
