René Herse 700 x 31 Orondo Grade TC

The Orondo Grade is a modern tubeless road tire with the performance, comfort and ride feel that our Rene Herse tires are famous for. It’s rated to a max. pressure of 90 psi (6.2 bar)—enough for heavy riders and those who prefer a stiffer feel to their bikes. A high-tech liner keeps our supple casings airtight without making the tire stiff and sluggish.

We name our tires after the roads that inspire them: Orondo Grade is a 7-mile 10% climb up a side canyon of the mighty Columbia River. The Orondo Grade was the half-way point—and often decisive climb—of the near-mythical, now-defunct 285-mile cross-state race, S2S ‘Seattle-to-Spokane.’ (The photo shows Jan in the early 2000s leading the race up the Orondo Grade.)

TUBELESS & SEALANT RECOMMENDATIONS:

This tyre is tubeless-compatible, however if running tubeless on Rene Herse tyres we find the extralight casing can be tricky to set up and maintain, but the standard, endurance and endurance plus casings work well. We recommend using Orange Seal sealant. Check out Rene Herse’s guide to setting up tubeless tyres here.

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.
