One SpideRing to rule them all.
The Cannondale OPI SpideRing SL Chainring takes Cannondale's One Piece Integration to its extreme with this revolutionary new component. Combining the crank spider, inner-, and outer-chainrings into a single 3D forged piece of aluminum. Weighing in at just 160 grams, this featherweight SpideRing shaves weight off your bike while reducing deflection for a better shifting and pedaling experience.
The Cannondale OPI SpideRing SL Chainring is available in 53/39, 52/36, 50/34 chainring combinations.

Love the OPI Spidering - paired this with Hollowgram SI cranks and it runs great. Smooth shifting and very stiff and light. Have ridden it about 1000 miles and its running great so far. Seems like I will easily get thousands more with regular maintenance.
