René Herse Umtanum Ridge TC Tire 650B x 55, Dark Tan - Endurance

The ultimate 650B bikepacking tire is designed for rides where you don’t know what lies ahead. Umtanum Ridge is a steep and lonesome ridge in the central Cascade Mountains. It is so remote that European settlers never renamed it, and it carries its ancestral Native American name to this day.

The Umtanum Ridge’s large and widely spaced knobs grip tenaciosly when conditions get tough. On pavement, it rolls and corners like a slick thanks to its large and strategically placed knobs that don’t squirm and always put the same amount of rubber on the road. The Umtanum Ridge features our noise cancellation technology: The staggered tread blocks create overlapping noise frequencies that partially cancel each other. This means that on most surfaces, the Umtanum Ridge doesn’t just roll as fast as a slick – it’s also as quiet as a slick.

The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous.

The Umtanum Ridge is tubeless-compatible. For tubeless setup, we recommend SealSmart sealant. When used with tubes, we recommend SV13 or SV14 tubes.

Pro Tip: The noise cancellation improves further during the first 30 miles (50 km) as the sharp edges of the knobs wear off a little.
