The Wolf Tooth Powertrac Chainring works with your biomechanics to achieve optimal efficiency and power with every pedal stroke. Not only will you gain more power, but you will also benefit from greater traction, and less shifting. Wolf Tooth's proprietary design is less ovalized than its competitors, eliminating the funky, uneven pedaling sensation while delivering the optimum pedal stroke. Just like Wolf Tooth's other single speed chainrings, the Powertrac features Drop-Stop tooth profile that holds the chain snugly to the chainring. Wolf Tooth offers PowerTrac Elliptical rings in a wide variety of sizes to fit all major brands' cranks. Just pick your size and configuration, order, install, and start pedaling as normal - your new oval rings will do the rest!

I was hesitant to try oval chainrings, as I read mixed reviews. However, this ring is a work of art! Impeccably machined, decent amount of support on Wolf Tooth website, and the chain mounts very securely on the ring. I have this on my hybridized front-squish commuter MTB with e*Thirteen cranks, and sunrace MX8 11-46t cassette. Chainline is awesome (looks a little dramatic in the lowest gear, but to be expected). The biomechanics of the oval have helped with my knee pain, too. The only gripe I have, is that 32t is almost not enough top end for commuting, but is great on the hills!
