Chain rings

The new Shimano XTR, XT, and SLX 12spd Hyperglide+ chain works differently than other products on the market so Wolf Tooth engineers developed a completely new tooth profile to provide optimal chain retention and durability when using this new chain technology.

- The new HG+ chain interacts with the chainring much differently than a traditional wide/narrow design. Wolf Tooth engineers spent the time to understand how the system works and design a new tooth profile that is optimized for this system.
- Engineered proprietary tooth profile maintains the quiet and smooth performance of the HG+ drivetrain with legendary Wolf Tooth chain retention.
- Prevents premature ring and chain wear that can come from non-optimized profiles.


Compatibility

- Compatible with Shimano 12-speed Hyperglide+ chains
- These rings fit on the Shimano XT M8000, SLX M7000 or Deore M6000 1x or 2x cranksets
- Not compatible with Deore triple (3x) cranksets

Looking for a 1X chainring for your new XTR M9000 crankset with the proven chain retention of our Drop-Stop® chainrings? Wolf Tooth has what you need! These chainrings fit only the Shimano XTR M9000 and M9020 cranksets (race and trail respectively). They have an asymmetrical 96 mm BCD with built-in threaded standoffs to provide the ideal 1X chainline.

- Fits 96 BCD XTR M9000 and M9020 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 fit on the Shimano XTR M9000 and M9020 1x or 2x cranksets
- Use only the stock Shimano XTR chainring bolts (M7)
- You will not use the stock bolt caps when mounting this ring. The stock bolts will thread into the chainring’s standoffs from the outside of the crankset.
- For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)

- Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains.

- 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 - 49 mm for 30-34T and 50 mm for 36T. Provides a great chainline on most boost bikes.

Designed for racing, and for those looking to optimize each detail in pursuit of speed, Wolf Tooth Aero Chainrings are strong, lightweight, and profiled to mate perfectly with your crankset for a clean, integrated look.

- 4 bolts are included. Torque to 5 Nm.

Recommendations

If you plan to ride in very muddy conditions, we recommend a chain guide or chain keeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chain drops and/or chain suck.

Designed for racing, and for those looking to optimize each detail in pursuit of speed, Wolf Tooth Aero Chainrings are strong, lightweight, and profiled to mate perectly with your crankset for a clean, integrated look. Taking advantage of 1x drivetrain systems and wider-range rear cassettes, Aero Chainrings are available in sizes 46T to 52T to provide similar overall range to standard 2x drivetrain configurations.

* * NOTE: This is a CAMO BashSpider ONLY. A CAMO Chainring is required to complete this system.

The CAMO BashSpider is the world's only crankset-mounted boost bash ring. This is a spider with an integrated bash ring for use with direct mount SRAM cranksets. The CAMO BashSpider pairs with a CAMO chainring to complete the CAMO System.
The "rolling" ability of the BashSpider allows the rider to move easily over obstacles. Bash rings that are mounted on the crankset are better supported than bash rings that are mounted to the frame or bottom bracket, as bash solutions like ISCG 05 can void frame warranties.
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: wear and shifting precision
- Optimal material usage: weight, stiffness, and wear
- Price: less expensive replacement chainrings
- Swapping simplicity: quick chainring change with five small bolts and no nuts
- Availability: Wolf Tooth has everything for your direct mount needs—round or oval, stainless or aluminum, no matter the crankset
- Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability

This is a CAMO Spider ONLY. A CAMO Chainring is required to complete this system.

This is a spider for use with the Cannondale cranksets that have a removable spider.

More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) chainrings. Our proprietary design means a slightly less ovalized ring (10%) with less aggressive timing (112°) than competitors’ versions; any change to your pedal stroke is unnoticeable for most riders, but they still provide the POWER and TRACTION benefits inherent to oval chainrings.

It’s like having two chainrings in one! With PowerTrac Elliptical rings, the larger-diameter section of the ring engages with the chain at the optimal point on the downstroke, or “Power Zone,” – between 1-5 and 7-11 on a clock face – to take advantage of your body’s natural biomechanical POWER: For example, during this section, a PTE 34t ring is equivalent to a 36t round ring. Similarly in the “Recovery Zone” (11-1 and 5-7), the smaller section on the PTE ring engages, maximizing EFFICIENCY in the weakest part of the pedal stroke; here the PTE 34t ring is equivalent to a 32t round ring.

Additionally, the above provides a smoother, more efficient pedal rotation, which means better TRACTION. Steadier torque on the rear wheel means less spinning out in the “Power Zone,” while pedaling is easier during the “Recovery Zone,” so you maintain momentum.
