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). Bon Jon Pass is accessed via a relatively smooth gravel road on the Olympic Peninsula. The moderate gradient allows you to let your bike fly, and these tires are perfect for surfaces like that.
On pavement, the Bon Jon Pass will outcorner narrower tires thanks to its greater width and its lower pressure, both of which keep more rubber in contact with the road surface. The Bon Jon Pass will glide over chipseal where narrower or less supple tires will chatter. If your bike can fit this tire, you won’t be disappointed.
The Bon Jon Pass is tubeless-compatible in both standard and extralight casing.
