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.

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.

Origin-8's Alloy Non-Ramped Chainrings are CNC-machined in the USA out of tough, light and durable 6061-T6 aluminum and are compatible with 8-, 9- and 10-speed drivetrain components. They feature an attractive and corrosion-resistant black anodized finish.

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

Wolf Tooth was first to market with Cyclocross 1x specific chainrings because we saw Cyclocross as the perfect use for our patent pending Drop-Stop technology. These beautifully machined 110 BCD Asymmetric 4-bolt chainrings are optimized for your 1x Shimano CX/ Road/ Gravel drivetrain whether you run Dura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700. They are also offset for the ideal 1x chainline. Compatibility: - These rings are for use with 110 BCD Asymmetric 4-bolt cranks. - Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703, and Tiagra 4700 - Sizes 38T and larger are compatible with Dura Ace 9100, Ultegra 8000 and 105 R7000 but a slight modification is required due to a change in the crank arm profile. The 36T chainring will not work for this modification. - Mounts in the big ring position of the cranks but is offset inward for perfect chainline. - The stock 2x bolts will not work. You will need 6mm bolts which are optimized for single ring mounting. - For 1x9, 1x10, 1x11 and 1x12 drivetrains including SRAM Eagle (TM) - Compatible with all 10, 11, and 12 speed chains including SRAM Eagle (TM) - If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention).

Origin8's Thruster 110mm BCD 5-bolt chainrings are great for road, 'cross, and gravel applications. Their Narrow/Wide tooth design offers outstanding chain retention on 1x systems, and they're 10 or 11 speed compatible. - Forged and hard anodized AL6061-T6 alloy construction - BCD: 110mm 5-Bolt - Type: 1x - Chain Compatibility: 10/11s - Tooth Type: Narrow/Wide

Original equipment on SRAM and Truvativ cranks, they also work well with other drivetrains. - 7000 series aluminum provides strength and durability

- Better chain engagement for greater chain retention - Special gear teeth profile designed for MTB riding usage - Smoother driving even over bumpy terrain - For XTR FC-M9100-1, M9120-1 cranks

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.

Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition. - Nickel plated Duraluminum for durability (SIS compatible) - Always match E type large ring with E type small rings

The SRAM X-Sync STEEL 1x chainrings are the perfect replacement ring for the cost conscious with added durability of steel.

Add some style to your park bike with Specialize's P.Series Sprocket. CNC'd from light and strong 6061 aluminum, this sprocket helps you crank hard for that next kicker or drive into the next berm. It's for 19mm x 48-spline spindles.

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 chains - Material: Aluminum

That big ring always seems to wear out first, and is the first to take damage when you're blasting over obstacles. Shimano's SLX M7000 11-Speed Chainrings for double cranksets get you back on the trail in no time. - 34T for use with 24T inner ring - 36T for use with 36T inner ring - 38T for use with 28T inner ring

The Patrol sprocket is based on the classic racing sprockets of the past. This one uses a high-quality full CNC construction and offset teeth for a perfect chain line. This thing was designed so you could crank it fast, so bolt one onto your bike and see just how fast you go. - Full CNC 6061-T6 alloy - Thickness: 6.35mm - Bolt drive version only - Made to fit directly on to a 24mm crank spindle, includes adaptors for 19mm and 22mm spindles

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.

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.
