The ultimate expression of our all-road tires – perfect for a new custom bike or to convert your old mountain bike into a competent all-road bike. The 54-mm Rat Trap Pass is incredibly plush, yet thanks to the smaller 26″ wheel size, your bike will be nimble like a good road bike.

We name our tires after the passes in the Cascade Mountains that inspire them: Rat Trap Pass bridges the gap between the mighty Suiattle and White Chuck Rivers. The road is rough in places and smooth in others, and the extra volume increases your confidence and speed. On pavement, the grip of the Rat Trap Pass is incredible – think race car with ultra-wide tires. These are the tires our team uses for the Oregon Outback, Unbound XL, Arkansas High Country Race and Dark Divide 300.

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

The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse.
