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.

This chainring works fine with my SRAM 1x drivetrain but was a pain to install on my Force hidden- bolt crankset. The internet offers how-to tips on removing and re-installing the spider, but the process isnt self-evident if youre used to working with traditional bolt-on chainrings. SRAMs packaging includes no instructions.
Both chainrings on the 2010 cross bike were toast, so installed this to convert to a 1X. Outstanding! Never drops off the chainring from 10 to 32 tooth cogs, ever. Love the 1X systems, for cross or gravel-grinder it's the tool of choice.
