Tooth utilize our proprietary PowerTrac design, which offers all the benefits of oval chainrings, but without the strange, uneven pedal stroke. \u003c\/span\u003e\u003cspan\u003eRide with it once and you'll wonder why you waited so long to try oval.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan\u003eThink of an oval chainring as two chainrings in one. \u003c\/span\u003e\u003cspan\u003eA major advantage of oval is that the shape of the chainring changes your gearing in two key phases of your pedal stroke by utilizing the natural biomechanics of your body. \u003c\/span\u003e\u003cspan\u003eThis is how it works. \u003c\/span\u003e\u003cspan\u003eThe area of the chainring with the larger diameter engages the chain optimally during the downstroke, the so-called power zone. \u003c\/span\u003e\u003cspan\u003eIf you were to look at a clock, the power zone would be between 1-5 and 7-11. \u003c\/span\u003e\u003cspan\u003eConversely, the recovery zone – back to the dial, between 11-1 and 5-7 – is the weakest part of the pedal path, where the oval maximizes your efficiency. \u003c\/span\u003e\u003cspan\u003eAn oval 34T chainring behaves like a 36T chainring when you need power, while it behaves like a 32T chainring when climbing.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan\u003eWe have also designed our oval chainrings to allow for a smoother and more efficient pedal rotation. \u003c\/span\u003e\u003cspan\u003eThis results in better traction due to the more even torque at the rear wheel. \u003c\/span\u003e\u003cspan\u003eWith an oval Wolf Tooth chainring, you can utilize more power in the power zone while pedaling more easily in the recovery zone.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThese chainrings
