Wolf Tooths PowerTrac Elliptical (PTE) chainrings were designed to facilitate more power, better traction, and less shiftingwithout funky uneven pedal stroke. Their proprietary design features a slightly less ovalized ring (10%) with less aggressive timing (112) than standard versions.

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 bodys natural biomechanical power: 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.

This design 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.
