Oval chainrings may look radically different than their round counterparts, but not all oval rings share the same attributes. Wolf Tooth Components’ PowerTrac Elliptical rings feature reduced ovality and more aggressive timing than the competition. Why? According to Wolf Tooth, the PowerTrac design offers more power and traction but without the uneven pedal stroke commonly associated with more aggressively shaped chainings.
Do Wolf Tooth’s PowerTrac chainrings deliver the best of both worlds? Stay tuned…

Wilderness Trail Bikes (aka, WTB) has been cranking out dirt-worthy components for 35 years. Recently, however, the company turned more than a few heads with the release of their high-volume Byway and Horizon road-plus tires. Located in Marin County, the WTB crew has access to some of the finest road riding that California has to offer. And it’s precisely that type of riding that inspired WTB to develop their line of high-performance Exposure road tires.
Available in 700×30, 32, and 34 millimeter sizes ($79.95 MSRP), the Exposure utilizes WTB’s lightweight, supple casings and folding, tubeless-compatible beads. All three sizes feature black tread and sidewalls, which are complemented by the tires’ subtle, grey graphics. With a published weight of 320 grams for the 32 mm size, our sample tires weighed 314 and 319 grams. Straight out of the box, the Exposures measured exactly 32 mm wide on DT Swiss tubeless RR511 rims (17.8 mm internal width).
