The Barlow Pass tires is named after a pass on the Mountain Loop Highway, a scenic gravel road through the central Cascades. The road leads past the ghost town of Monte Cristo before ascending the pass. On the long straights and sweeping turns of this gravel road, the extra stability of a large-wheeled bike can provide an advantage as you descend at high speed. The Barlow Pass is a great road tire for 700C bikes with moderately large clearances. If you prefer a true dual-purpose knobby in the same the 700C x 38 mm size, check out the Compass Steilacoom. The Barlow Pass is tubeless-compatible. When used with tubes, we recommend the SV17 or SV18 tubes.
