Chainrings

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.

absoluteBLACK Oval Direct Mount 1x Chainrings for SRAM greatly improve traction and climbing abilities. They are designed for SRAM cranks that have a 3-bolt direct mount interface and removable spider. Direct mount chainrings provide significant weight savings over a standard spider and chainring combination. They are crafted from CNC machined 7075 aluminum and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2-14.4%, with timing of 110.5-116.3° after TDC (top dead center). - Oval shape reduces stress on knees, helps to keep your legs fresh, and does not feel any different while riding - The unique, patent-pending narrow-wide tooth profile keeps the chain in place - Teeth have been 3D-machined for ultimate mud shedding and quieter operation - Provides excellent weight-to-strength ratio - 6mm offset is designed for 135/142 spacing on standard DUB/GXP/Long-Spindle BB30, as well as 170/177 spacing on fat bike cranks

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.
