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.

Shimano's Ultegra 6800 chainrings provide confidence-inspiring shifting and category-defining speed. Cold-forged aluminum comprises the super-stiff, hollow outer ring, and Shimano's unique system of ramps and pins means lightning fast shifts are at your command.

Replace worn out chainrings or change out gearing with SRAM's RED X-Glide Chainrings. These solid rings are crafted from aluminum using SRAM's X-Glide tooth profiles for quick, responsive shifting. If you have a SRAM RED 10-speed Exogram* standard crank, these are the rings for you. RED Exogram cranks have a hidden 5th bolt behind the crank arm

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.

SRAM's XX1 X-Sync Chain Ring mates perfectly to SRAM's XX1 crank. It features a wide-narrow-wide tooth profile to securely hold the chain through the roughest terrain, no chainguide necessary. A variety of sizes ranging from the spin-to-win 28T to the hard-man humbling 38T let you dial in your rig for your strengths or terrain. The unique chainring design allows you to slide slide over the crank arm, so crank removal is not required.

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

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.

Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition.

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

Wolf Tooth designed these bolts to be the best on the market. These optimized single chainring bolts have a 4mm hex socket on the bolt and a 6mm hex socket on the nut...that's right, no more spanner for your single ring bolts! These are 6mm long so they work perfectly with any bolt on single chainring that does not have threaded standoffs. - 6mm length - Made in the US out of 7075 Aluminum Alloy - Has hex heads on both the bolt and nut for easy installation - Max torque of 6-7 Nm with light grease on threads only

Wolf Tooth designed these bolts to be the best on the market. They have a 4mm hex socket and are 10mm long so you can use a bash ring with your chainring that has threaded standoffs like the Wolf Tooth 104 BCD 30t ring, Elliptical 104 BCD rings, 76 BCD rings and others. No nuts are included with these bolts as they are intended for use with threaded chainrings. These work great with Wolf Tooth or any other brand threaded M8 x 0.75 chainrings.

Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains SRAM has ever made. The radical new look and feel of the 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. The longer, positive-rake tooth shape has been designed to work perfectly with Eagle chains to increase chain retention and overall pedaling efficiency, while decreasing friction, noise, and wear. The complete Eagle system—crankset, chainring, chain, shifter, derailleur and cassette—is designed, tested, and proven to deliver the ultimate mountain bike drivetrain. Put simply, Eagle is capable of revolutionizing the ride for all riders on every kind of terrain. - Designed to be used with Eagle chain - Material: Steel
