Description of Wolf Tooth Elliptical - Single Chainring 96mm for Shimano XTR M9000/ M9020 - Drop Stop - black

The oval Wolftooth chainrings allow you to upgrade your 96  mm BCD Shimano XTR crank to 1x10, 1x11 or 1x12-speed. Beautifully machined to match up with the arms of your crankset.

Get better traction and acceleration when you use Elliptical (or Oval, same thing) rings!
The simplest way to explain how they "feel" is that where your pedal stroke is weakest it feels like you have a 2 teeth less on the chainring and where you have the most power it feels like you have 2 more teeth. They feel this way because with the radius of the chainring constantly changing, the torque needed to turn the cranks is constantly changing to better match your power output. Example: a 34t chainring feels like a 32t in the weak part of your pedal stroke and a 36t in the part of the stroke where your legs have the most power.

Wolf Tooth's patent pending Drop-Stop wide/narrow tooth profile for the ultimate chain retention and mud shedding ability. Recommended is the use of a clutch style rear derailleur for the best chain security.

For Shimano XTR M9000/9020 cranks with 96mm BCD.
Chainline: 49 mm for 30-34T

Optimized for 10/11-spd chains, 9-spd may be to loose.

Note: Use only the stock Shimano XTR chainring bolts. The Wolf Tooth chainring bolts are a different size.

Powertrac

More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) chainrings. The 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.
