Chainrings

Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition.

Mud and moving parts are enemies in the sport of cyclocross. That's why SRAM decided they were going to simplify things. Remove the front derailleur, increase the range of the cassette, make dropped chains a thing of the past, and you've got a cross drivetrain worthy of hammering. SRAM's CX1 X-Sync Chain Ring is an integral part of that system. It mates to 110 BCD cranks and features a wide-narrow-wide tooth profile to securely hold the chain through the roughest terrain. It's also specially designed with mud clearing in mind to keep your rig light and fast. A variety of sizes ranging from the spin-to-win 38T to the flat-out 46T let you dial in your rig for your strengths or course.

SRAM's road chainrings are stamped from 7075 aluminum for low weight and excellent strength. The teeth are ramped and pinned for precision shifting, too.
