The Rene Herse Steilacoom (formerly known as the Compass Steilacoom) is a gravel bike tire with a versatile tread pattern that is usable in a large range of conditions from smooth pavement up to mud and snow. Rene Herse claims this "dual-purpose knobby tread" always keeps the same amount of rubber on the road whether it's rolling forward or leaning into a turn. Despite the big knobs on this tire, they also claim this tire is faster than most road tires on pavement.


The Steilacoom is only available in the 700x38c size as, unlike other brands, Rene Herse gives all sizes of their tires a different name which can be confusing if you're not really into this brand. As far as we can see, the Rene Herse Hurricane Ridge 700x44, Oracle Ridge 700x48, Fleecer Ridge 700x55, Pumpkin Ridge 650x42, and Juniper Ridge 650x48 are all essentially the same tire featuring the same construction and tread pattern.


We've tested the Steilacoom with the Standard casing that is their most affordable option and comes in at 445 grams. Other options (at a premium) are the Extralight casing that saves about 60 grams of weight and the Endurance casing that is made up of the Extralight casing with an extra layer of puncture-resistant material that runs from bead to bead and also comes in at 445 grams. All versions of the Steilacoom are tubeless-ready.


Back in 2018 we already tested the Bon Jon Pass 700x35c (review in the touring bike section) that was still branded Compass. We found the Bon Jon Pass to be a relatively fast tire for a touring bike tire but it didn't provide the puncture protection you'd expect from a touring bike tire.


Let's see how the Steilacoom fares when we compare it against other gravel bike tires.

The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width.

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

The Rene Herse Steilacoom ends up in the mid-field with its main strength being the huge knobs that make this tire suitable for a very large range of conditions. Its biggest weakness is the low puncture resistance of the tread but especially the sidewalls that are also quite thin for a gravel bike tire. We also find the Steilacoom to be a bit small for a 38-622 rated tire. if you're looking for volume, definitely get one of the bigger versions of this tire.


Coming back to Rene Herse's claim of the Steilacoom being faster than most road bike tires on pavement: we can't confirm that claim. The Steilacoom comes in at 23.8 watts at 60 psi / 4.1 bars while an average 25-26 mm wide road bike tire comes in at ~ 15 watts at the equivalent pressure of 80 psi / 5.5 bars (~ same comfort level).


Not a bad tire but we're not convinced of the price/performance of these tires as they do not provide magic performance in our tests.
