Cannondale Hollowgram SpideRing One-Piece Chainring Spider 53/39T

Cannondale SpideRing One-Piece Chainring & Spider – Hollowgram (KP245)

The Cannondale SpideRing is a one-piece combination chainring and spider, engineered to dramatically increase stiffness while reducing weight. By eliminating the traditional multi-piece spider and chainring setup, Cannondale’s One Piece Integration delivers faster, more precise shifting and improved power transfer in a simpler, lighter system.

Weighing just 175 grams in the standard 53/39T configuration, the SpideRing is both a performance upgrade and a precision-machined work of art. Originally spec’d on 2013 Hollowgram SiSL2 cranksets, it remains backward compatible with virtually all Cannondale Hollowgram cranksets, making it an ideal upgrade or replacement option.
