Chainrings

Surly's Stainless Steel Chainrings last longer than their aluminum brethern because the 304 grade metal they use is 35% stronger. The rings aren't pinned or ramped so when one side starts to wear you can flip it around and pedal some more! They work great with singlespeed, fixed, and 1x9 applications, and the teeth are 2.1mm thick so they work well with 9-speed chains.

The radical look and feel of SRAM's X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. They subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagle drivetrain’s performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.
