HollowGram SpideRing SL 10 arm

This Cannondale SpideRing is a one-piece combination of spider and chainring, meant for use with Cannondale Hollowgram cranksets. This technology improves chainring stiffness in order to provide top shifting performance. What's more, it only weighs 174 grams in a standard 53/39T configuration. The SpideRing 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 compatible with SRAM 10-speed and 11-speed road and Shimano 11-speed road drivetrains.
