Our revolutionary dual-purpose knobbies as a 26″ version. Humptulips Ridge, the place that inspired these tires, is at the southern edge of the remote Olympic Mountains. A beautiful narrow gravel road climbs one side of the ridge, then descends the other, in an otherworldly loop that ranks among the best riding experiences anywhere.

The Humptulips Ridge grips like a knobby when conditions get tough. On pavement, it rolls like a slick tire thanks to its large and strategically placed knobs that don’t squirm and always put the same amount of rubber on the road.

The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. 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 Endurance Plus casing provides the ultimate in sidewall protection for extremely tough conditions.

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