By combining tall square teeth and sharp narrow teeth, X-Sync™ chainrings provide the performance needed for SRAM's 1 x 11 'cross group. The tall teeth engage the chain earlier than a traditionally shaped chainring, and the narrow teeth help manage deflected chains, especially when paired with this chainrings chamfered edges. Made with the durability needed to stand up to the rigors of cyclocross racing, and with mud clearing recesses to help keep your chain clean, these chainrings are key to SRAM's cyclocross oriented CX1 group.
SRAM CX1 X-Sync Chainrings are available in sizes 38T (68g), 40T (73g), 42T (75g), 44T (85g), and 46T (98g). 110 BCD. Compatible with Quarq power meters.
