The Cannondale OPI SpideRing SL Chainring is a revolutionary new component of the Cannondale Hollowgram cranksets. Taking the One-Piece Integration to its logical conclusion, the SpiderRing combines the crank spider, the inner chainring and the outer chainring into one piece of forged aluminum. The 3D-forged, 10-arm design cuts weight without sacrificing shift quality or durability, weighing in at just 160 grams (50/34).
The Cannondale OPI SpideRing SL Chainring is available in 53/39, 52/36, 50/34 chainring combinations.

I was looking for a Spidering for my Cannondale SISL2 crankset and this was exactly what I was hoping for. It is lightweight and the price with Biketiresdirect was excellent. Couldn't be more pleased.
