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.

SRAM's X-Sync Boost Direct Mount Chainring features tall teeth with alternating tooth profiles that hold the chain amazingly well and still provide space for mud to clear. - Chainring BCD: SRAM BB30 Direct Mount, SRAM GXP Direct Mount - Color: Black - Drivetrain Speeds: 10, 11 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring - Offset: 3mm

More power, better traction, less shifting. Wolf Tooth oval chainrings use our proprietary PowerTrac design that has all the benefits of oval, but without the funky, uneven pedal stroke. Ride one once and you'll wonder why you waited so long to try oval. Think of an oval chainring as two chainrings in one. A major benefit of oval is how the shape of the chainring alters your gearing in two important phases of your pedal stroke by harnessing your body's natural biomechanics. Here's how it works. The area of the chainring with the larger diameter engages with the chain at the optimal point on the downstroke, which is what's known as the Power Zone. If you were to look at a clock, the Power Zone would be between 1-5 and 7-11. Conversely, the Recovery Zone – back to the clock face, between 11-1 and 5-7 – is the weakest part of the pedal stroke, when the oval maximizes your efficiency. A 34T oval chainring behaves like a 36T chainring when you want power, while behaving like a 32T chainring when you're climbing. We've also engineered our oval chainrings to provide smoother, more efficient pedal rotation. This equates to better traction because of steadier torque on the rear wheel. With a Wolf Tooth oval chainring, you can harness more of your strength in the Power Zone, while having easier pedaling in the Recovery Zone. These chainrings are for Shimano GRX cranks. They feature our patented Drop-Stop® design for the best wear life, chain retention, and mud clearance. Drop-Stop ST is specifically for the Shimano 12-speed Hyperglide+ chain, which is used by GRX 12-speed. Drop Stop-B works with all other 9, 10, 11, and 12-spd chains, including SRAM Flattop. Compatibility: - Shimano GRX cranksets including RX600 and RX810 - Drop-Stop ST is designed for Shimano 12-speed Hyperglide+ chains - Drop-Stop B tooth profile is compatible with SRAM Flattop chain - Wolf Tooth's patented Drop-Stop wide/narrow tooth profile provides the ultimate chain retention and mud-shedding ability - Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-Type) Flattop chains, 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo. DROP-STOP B - Compatible 9, 10, 11, and 12s SRAM Eagle, 12s SRAM Transmission (T-type) Flattop, 12s Campy, 12s KMC - Not compatible with 12s Shimano HG+ 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.

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. - Fits 110 BCD Asymmetric 4-bolt Shimano cranks - 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: - Fits 110 BCD asymmetric 4-bolt cranks - All sizes compatible with Dura Ace 9000, Ultegra 6800, 105 5800, RS510, Tiagra 4700 or 4703, Sora R3000 or R3030, and Claris R2000 or R2030 cranks. - 38-50t are compatible with 105 R7000, Ultegra R8000, and Dura-Ace R9100. The 36t chainring is NOT compatible with these cranks. - NOT compatible with Dura-Ace R9200, Ultegra R8100, and 105 R7100 Cranks - Size 42t and larger will work with the Dura Ace 9100 power meter - 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 our 6mm bolts which are optimized for single ring mounting. - If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention - Chainline 47.5mm - Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-Type) Flattop chains, 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo. DROP-STOP B Compatible 9, 10, 11, and 12spd SRAM Eagle, 12spd SRAM Transmission (T-type) Flattop, 12spd Campy, 12spd KMC Not compatible with 12spd Shimano HG+ chains
