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 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 officially compatible with SRAM 10-speed road and Shimano 11-speed road drivetrains. We suspect that it will run fine with Shimano 10-speed drivetrains, but have yet to try it ourselves. Installation is easy using the same lockrings (KP021) and lockring tool (KT012) Cannondale has always used.
