Cannondale Hollowgram MTB Spidering X-Sync 30t SI

Our price $159.95

Part number CU4041SI30

Cannondale's new SpideRing is a one-piece combination of spider and chainring, improving chainring stiffness that improves shifting performance. This SpideRing is standard on the new 2016 onwards Hollowgram cranksets featured on the Cannondale Fsi. Cannondale's One Piece Integration concept reduces the number of parts which improves performance in a simpler system. This ultralight and durable SpideRing is designed for the MTB world, with a 10-arm, radial arm design with X-Synch thick/thin tooth profiles for chain retention and only 46 grams (30t). The crank-arm interface on these rings is not keyed, so the rings can be rotated 90 degrees for maximum longevity.

Use the KT012/ Cannondale tool for spider removal / installation:
