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.

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 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.

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

Replace worn-out chainrings or change out gearing with SRAM's Yaw Compatible Inner Chainring. This solid ring is crafted from aluminum using SRAM's X-Glide tooth profiles for quick, responsive shifting. This chainring works for SRAM's Yaw front derailleurs on both 10- and 11-speed drivetrains. The 42-tooth version works best when paired with a 55- or 54-tooth big ring.

Chromag's Sequence chainring uses X-SYNC technology licensed from SRAM for unmatched chain retention. So now, no matter what kind of riding you do, you can have the peace of mind that your chain will stay put, and you can give your bike a little extra flair with the timeless Chromag styling. •104mm BCD

Replace worn out chainrings or change out gearing with SRAM's Force X-Glide Chainring. This solid ring is crafted from aluminum using SRAM's X-Glide tooth profiles for quick, responsive shifting. If you have a SRAM Force 22 compact crank (50/34), this is the ring for you.

The new chainrings are stainless steel and have improved ramps, gates, and pins for better shifting performance.

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.

This is Tom Dugan’s all new signature sprocket. In addition to its classic look, the Fang increases in thickness towards the center of the sprocket for increased strength. - 7075 Aluminum - Sweet machining

Mud and moving parts are enemies in the sport of cyclocross. That's why SRAM decided they were going to simplify things. Remove the front derailleur, increase the range of the cassette, make dropped chains a thing of the past, and you've got a cross drivetrain worthy of hammering. SRAM's CX1 X-Sync Chain Ring is an integral part of that system. It mates to 110 BCD cranks and features a wide-narrow-wide tooth profile to securely hold the chain through the roughest terrain. It's also specially designed with mud clearing in mind to keep your rig light and fast. A variety of sizes ranging from the spin-to-win 38T to the flat-out 46T let you dial in your rig for your strengths or course.
