Your cart is empty.More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooths 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. Its 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 bodys 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.

I'm not sure why I waited so long to try an oval chain ring. Installing it on my Force crank with direct attach was very easy. I didn't even have to change my chain length. Initial impressions are very good. My pedal stroke feels much smoother and my upper body is much more quiet even during hard efforts. I found myself staying in the harder gears for longer and feeling less fatigue overall. I'm sure it's not for everyone, but I'm drinking the kool-aid fully on this one. I may never go back to round.

Truly dedicated to their craft, Amazon has created a custom package to match this product. I assume all their other items follow suit.One minor issue, since installing this ring, I can’t find my bike. It just disappeared. There has been an uptick in wizard, golum, giant eagle, and hobbit traffic on street but that is probably just a coincidence.

Fits perfect and is very light. Upgraded from a 1x SRAM 32t chainring to this larger one. Remember you will need to replace your chain if going up in teeth. The oval shape sounds promising based on others opinions.
