Note: This is a CAMO Chainring ONLY. A CAMO Spider is required to complete this system. The CAMO chainring system was created by the Wolf Tooth engineers for Chainline And Material Optimization on direct mount style Chainrings. The key advantages include: - Perfect chainline - for wear and shifting precision - Optimal material usage - for weight, stiffness, and wear - Price - for less expensive replacement chainrings - Swapping - Very fast chainring change out with 5 small bolts and no nuts. - Availability - Wolf Tooth is the one-stop-shop for your direct mount needs...round or oval, stainless or aluminum, and no matter the crankset. - Bling!! - spider colors and bolt colors add a little flash to your sweet ride. - Wolf Tooth's patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability Compatibility: - This is a chainring for the Wolf Tooth CAMO spiders. It is NOT compatible with any other chainring mountings. - The CAMO spiders come with Stainless Steel Bolts. - 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). - Chainline - varies by which spider you choose - 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.

The Wolf Tooth 107 BCD Chainring for SRAM Cranks is compatible with most new SRAM 1x road cranks that use the 107 BCD spider, including the SRAM AXS Power Meter Spider. This chainring uses the patented Wolf Tooth Drop-Stop B Wide/Narrow tooth profile that is optimized for drop bar bikes. - Fits 107 BCD for SRAM Cranks - Drop-Stop technology prevents dropped chains. 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 while reducing friction. - Cranks that use the 107 BCD spider also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Direct Mount Chainrings for SRAM 8-Bolt 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. - 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 (like our GnarWolf) in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck. - Recommend the use of a clutch-style rear derailleur for the best chain security. Tech Specs: - Material: 7075-T6 aluminum - Weight: 38t/75g | 40t/78g | 42t/86g - Made in the USA

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.

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 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.

The direct mount chainrings for SRAM cranksets with the 3-bolt mounting interface. They replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet.
