Chainrings

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

An issue many people ran into when they began using 1x setups was chain retention with the front chainring. In the beginning of the 1x movement, many companies dealt with this by using aftermarket chain keepers that somehow bolted to the frame. Many people discovered that using a narrow-wide chainring in conjunction with some type of 'clutch' rear derailleur helped abate or eliminate these chain-jumping issues. Narrow-wide rings use alternating tooth profiles that more positively engage the chain and help control a deflecting chain in bumpy conditions. Your friends at Surly have partnered with SRAM to bring you stainless steel X-Sync chainrings. Stainless Steel is durable. This durability is pretty useful when you're talking about the one ring that is bearing the brunt of all your miles.

- AXS enabled for easy monitoring and firmware upgrades - Fully integrated power meter into a direct mount chainring - Power readings are accurate within +/-1.5% and aren't affected by climate conditions during a ride - Power balance measures left and right legs separately - SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control - Laser-etched chainring finish is more durable - 8-bolt direct mount compatibility only to RED and Force eTap AXS cranks. - Speeds: 12 - Chainring material: Aluminum - Power Meter Type: ANT USB

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 2.2 - 2.3mm thick so they work well with wider chains.
