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.)

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. 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 Orondo Grade is tubeless-compatible. For tubeless setup, we recommend SealSmart sealant.

Pro Tip: While the Orondo Grade can be used with tubes, we recommend our 700C x 32 Stampede Pass for use with tubes, unless you need the Endurance casing.
