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 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!
Elliptical design improves power and effeciency
Drop-Stop chain retention
Available in assorted sizes and colors
No funky elliptical pedaling sensation

In my quest for better climbing, I added a 32T wolftooth oval chain chainring. I am running a Shimno 11-42 in the rear with a WT 49T. The 32t feels like a direct replacement for the 30t. On the margin, there is good pressure at the beginning of the pedal stroke and it eases off at the bottom just enough to sweep and engage the hamstrings. My conditioning has improved since installing it, I may consider a 34t. I am doing most of my climbing now in the 28t and 32t rear cogs.
Not unless you're running a Singleator or other chain tensioning device that can account for the varying chain length (almost looks like a rear derailleur but for one speed). If you have an eccentric bottom bracket or standard bolts on a straight dropout that tension your chain to one set level all the time then you cannot run any sort of oval front chain ring.
