The radical new 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. 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. - Can be used with Eagle 12 speed or SRAM 11 speed chains - Direct mount rings with 3mm offset fit Boost geometry Eagle cranks; direct mount rings with 6mm offset fit traditional geometry - Eagle cranks and GXP spindle XX1, X01, X0, X1 and X9 cranks

Shimano Ultegra R8000 Series Chainrings are designed for use with Shimano's 11-speed Ultegra crankset.

FSA ATB chainrings deliver flawless shifting for any mountain drivetrain. Available in alloy and steel options.

RaceFace Narrow Wide Chainrings feature tooth profiling for chain retention and a blend of weight and durability suitable for XC, DH, and everything in-between. - 7075-T6 aluminum, aerospace grade strength - Compatible with 9, 10, 11 and 12 speed - Stiff 4mm plate thickness and I-beam construction transfer loads without flexing - Reversible laser etched graphics - Non-threaded bolt holes

• CNC machined from 7075-T6, one of the strongest alloys available today • Outer rings are made from 4mm thick material & inner ring from 5mm thick material for unsurpassed durability • Rings feature our patented S.H.I.F.T. technology, featuring hard-wearing steel S.H.I.F.T. chips for dual action up-shifts

The Shimano R9100 series crankset achieves the ultimate in optimal power transfer. It does this through a reinforced chainring on its unique asymmetrical four-arm spider construction. - Chainring BCD: 110 Shimano Asymmetric - Drivetrain Speeds: 11 - Material: Aluminum - Ring Position/Type: Inner

• New asymmetrical tooth profiling and more upshift and downshift zones yield instantaneous, smooth and quiet shifting • CNC-machined from super-hard AL-7075 to maximize wear resistance and impact strength • Three times stiffer than Team and Race rings • Double chainrings bolts are included with all Race Face chainring sets

Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition. - For best shifting performance B-type rings only with B-type rings

Shimano SLX M660 9-Speed chainrings get your drivetrain back to optimal operation.

The 88 BCD for Shimano's XTR M985 crankset was one of the first additions to our chainring line. We added this early on because this crankset is one of our favorites for durability, weight, q-factor, and aesthetics. These rings are beautifully machined to match the contours of the crankset. - Fits Shimano M985 race crankset - Drop-Stop® technology. On Wolf Tooth's patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction. - Alternating wide/narrow tooth pattern prevents chain derailment Compatibility: - This ring ONLY fits the Shimano M985 "Race" crankset that looks like this: - The Shimano M980 "Trail" crankset uses our 104 BCD chainrings in stainless steel or aluminum - 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). - Provide a great chainline on most boost bikes. See this explanation for details. - Chainline - 50mm Use Drop-Stop A or B for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains Recommendations If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck. Tech Specs: - Weight: 30t/44g | 32/55g | 34t/60g | 36t/70g | 38t/83g - Material: 7075-T6 aluminum - Made in the USA

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.

absoluteBLACK Round Direct Mount 1x Chainrings for Cannondale allow for flawless drivetrain setup for 1x9, 1x10, 1x11, and 1x12-speeds. They are designed for Cannondale Hollowgram cranks and are particularly suited for F-Si frames. 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. - The unique, patent-pending narrow-wide tooth profile keeps the chain in place - The specific offset helps to create a better chainline

- 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

Original equipment on SRAM and Truvativ cranks, these chainrings also work well with other drivetrains.

FSA's MTB Pro chainrings deliver flawless shifting for mountain drivetrains. - Precision CNC machined AL7075/T6 alloy - Shifting ramps and stainless pins for improved performance - Chainring is compatible with Shimano and SRAM 10/11-speed drivetrains - 8mm thickness
