The Barlow Pass is the sweet spot for most all-road bikes. These tires are named after the passes in the Cascade Mountains that inspire them: Barlow Pass is near the ghost town of Monte Cristo in the northern Cascades. The Barlow Pass is the perfect tire for rides that combine equal portions of pavement and gravel: light enough so your bike retains the nimble feel of a road bike, yet 38 mm wide to give you amazing traction on pavement and off.
