CX1 X-Sync Chainring

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.
