Hollowgram SL10 OPI SpideRing Chainring

Cannondale's new SpideRing is a one-piece combination of spider and chainring, improving chainring stiffness that improves shifting performance. Weighing in at just 174 grams (standard 53/39T configuration), this is a piece of art. The SpideRing is standard on the new 2013 Hollowgram SiSL2 cranksets, but is backward compatible with virtually all Hollowgram cranksets. Cannondale's One Piece Integration concept reduces the number of parts which improves performance in a simpler system.

SpideRing is 10 and 11 speed compatible.

Installation is easy using the same lockrings (KP021) and lockring tool (KT012) Cannondale has always used.
