Wolf Tooth was first to market with cyclocross 1x specific chainrings because we saw cyclocross as the perfect use for our Drop-Stop® technology. Since their release, the uses for these rings has expanded beyond cyclocross to commuting, gravel riding, and even full on-road applications with the giant 52t rings. - Fits 130 BCD 5 arm cranksets - 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: - These rings are for use with 130 BCD 5-arm cranksets. - Do NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800 - Not compatible with Campy CX10/11. - SRAM Exogram cranksets with inset nut must use stock fifth bolt + spacer(s). The Force CX1 bolt features a fifth bolt with 1x specific shoulder. This kit can be found online. - 38T important note: The chain may contact the spider arm slightly when using the 38T chainring (see last photo in the product images). We recommend filing a small chamfer on the spider arm but you can also just install it and let the chain do the work. This is only an issue with the 38T as the 130 BCD was designed for 39T smallest ring. - Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting. Tech Specs: - Weight: 38t/52g | 40t/60g | 42t/62g | 44t/79g | 52t/132g - Material: 7075-T6 aluminum - Made in the USA - This 1x chainring and can be mounted in either the inner or outer ring position of a double crankset but can not be used in a 2x setup. - Chainline - The most common mounting is in the outer ring position because of chainstay clearance. The ring centerline is ~2mm from the ring's mounting face so they usually sit about 2mm closer to the frame than the stock big ring (depends on the stock ring) 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. 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.

12 Good Reasons If you're looking for a bomber new chainring that can run with your Shimano 12 speed drivetrain, then look no further.

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 the 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. The direct mount chainrings for SRAM cranksets replace your existing spider and chainring with one clean-looking, lightweight, and stiff piece of machined billet. They are available in 3 different offsets: 6mm offset for 49mm chainline, 3mm offset for 52mm chainline, and 0mm offset for 55mm chainline and SRAM Transmission optimization. They are available in various tooth profiles to suit your drivetrain, including Drop-Stop B, which is optimized for SRAM T-Type Transmission and compatible with many other chains.

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.

"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 Race Face Cinch cranks such as Turbine, Next SL, Sixc & Aeffect. The Wolf Tooth Cinch chainrings feature our patented Drop-Stop® tooth profiles for the best wear life, chain retention and mud clearance. We have optimized tooth profiles for SRAM T-Type Transmission, Shimano Hyperglide+, and all 12, 11, 10, and 9-speed chains. Compatibility - Any Race Face Cinch™ system crankset (including Next SL, Sixc, Turbine, Aeffect) - Riders running SRAM Transmission w/ Race Face Cinch cranksets with a Boost 136/137mm spindle use a Cinch direct mount 0mm offset chainring. - Riders using a Cinch crankset with a Super Boost 151mm spindle use a Cinch direct mount 3mm offset chainring. - Standard (142mm rear hub spacing) 6mm offset, Boost (148mm hub spacing) 3mm offset, and Boost for T-Type Transmission 55mm chainline 0mm offset are available. - Use a 3mm offset chainring for Super Boost applications running standard drivetrains or Transmission. - Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability. - For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle) --- 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). - Maximum diameter is that of a chainring 2t bigger than the size you order (so be sure there is adequate chainstay clearance!) - Chainline 49mm (standard), 52mm (Boost), 55mm (T-Type Boost) - Available in multiple tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ and 12spd KMC chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains. Drop-Stop B is optimized for SRAM 12 spd Transmission (T-type) and Road Flattop chains but is compatible with all chains that work with Drop-Stop A. 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."

A total redesign of Odyssey's popular MDS sprocket. With a built-in full guard, this sprocket lives up to its name, helping to protect your chain from anything you can throw at it. Sprocket thickness increases towards the guard area for greater strength. Compatible with all chain widths. - 7075 Aluminum
