Optimize your 1x drivetrain with the Cannondale Hollowgram OPI 32T SpideRing.
Designed for performance-minded mountain bikers, this direct-mount chainring integrates a lightweight spider and chainring into a single forged aluminum piece for exceptional stiffness and durability. The precision-engineered X-Sync narrow-wide tooth profile improves chain retention and reduces the likelihood of drops — ideal for aggressive trail riding and technical terrain.
Built specifically for Cannondale Hollowgram cranksets, the CU4041SI32 SpideRing offers direct-mount simplicity without the need for a separate spider adapter. The 32-tooth size strikes a balance between climbing efficiency and high-speed rolling, making it a versatile choice for 10/11/12-speed 1x drivetrains.
Whether you’re upgrading a factory ring or refreshing a hard-used piece, this chainring delivers robust performance with minimal weight — perfect for trail, enduro, and cross-country riders.
