More power? Check. Better traction? Absolutely. Less chain drop? Yeah. Funky irregular pedal stroke? Not with Wolf Tooth's PowerTrac Elliptical™ (PTE) chainrings. Our unique design means a slightly less ovalised ring (10%) with less aggressive timing (112°) than competitors' versions; any change to your pedal stroke is imperceptible to most riders, but they still deliver the POWER and TRACTION benefits inherent in 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, in this section, a 34t PTE ring is equivalent to a 36t round ring. Similarly, in the "Recovery Zone" (11-1 and 5-7), the smaller section of the PTE ring engages, maximising EFFICIENCY in the weakest part of the pedal stroke; here the 34t PTE ring is equivalent to a 32t round ring.

Furthermore, the above provides a smoother and more efficient pedal rotation, which means better TRACTION. More consistent torque on the rear wheel means less slipping in the "power zone", whilst pedalling is easier during the "recovery zone", allowing you to maintain your momentum.
