The Yeti Arc Carbon Race is fast, efficient and climbed up and over the repeated rock step-up ledges on our test track in Sedona supremely well. The tires stuck tightly to the ground during the brief out-of-the-saddle bursts required to power up the repeated short, steep inclines. Wheel size was out-of-sight, out-of-mind while playing on slickrock and other trailside features.
