The Bon Jon Pass is our Goldilocks tire: at 700C x 35 mm, it fits bikes that have extra clearance around the Stampede Pass (32 mm), but not enough space for a Barlow Pass (38mm). We name our tires after the passes that inspire them: Bon Jon Pass is a remote pass on the Olympic Peninsula. The moderate gradient allows you to let your bike fly, and these tires are perfect for the smooth gravel surface of the pass and for the chip-sealed asphalt that covers the approach.

The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level.

The Bon Jon Pass is tubeless-compatible

The supple casing of our Rene Herse all-road tires rolls smoothly over surface irregularities. The tread pattern interlocks with the road surface for superior cornering grip, whether your roads are wet or dry. The tread has enough thickness in the center to last many miles, but it's thin and supple on the shoulders where it doesn’t wear. All models feature:
