I have a pair of Light-Bycicle RR46C02 (21mm ID) rims ordered and want to try a set of tires lighter than my current Pro Ones (25mm claimed, ~28mm measured on 20mm ID rims). The Compass Cayuse Pass EL 26mm looks like an interesting option, but I couldn't find how wide exactly the tire runs on wide rims. The response from Compass wasn't too helpful:
While I do not have a measured with of the Cayuse pass tires when mounted, I can tell you they will not be larger than 28mm. Our tires typically run true to listed size, or slightly smaller depending on the model.
Any relevant info will be appreciated.

I can tell you that my Grand Bois Cerf Vert 28mm tires come out to 30mm on 18c rims, so I'd expect the 26mm Cerf Bleu to be 28mm on the same rims.

The Grand Bois tires are also made by Panaracer with the same tech as the Compass ones. Jan Heine used to be the importer before he created his own brand.

My Compass tires all measure pretty close to the nominal sizes. I have some Yishin 21mm (internal) hookless rims and the 44mm Snoqualmie Pass tires measire right at 44mm. My 700x38 Barlow Pass measured 37mm on 19mm inner-width rims.

I love my big (fast!) Compass tires on my commuter/do-everything bike, but I wouldn't give up tubeless for the smaller sizes. I also have the RR46C02 wheels on my road bike and was using Pro One 28mm tires and now the 28mm S-Works Turbo 2bliss. The Schwalbe were a little bigger (the S-Works only measure 28-29mm, whereas Pro Ones were 30-31mm), but the S-Works feel great (maybe faster, though it's probably a difference that is lost in the noise). Both tires are great choices. I can't imagine running smaller than a 28 anymore. Or tubes, honestly.

If Compass did a smaller tire (32mm? 28mm?) tubeless, I would likely switch to using those. The 35mm tubeless-compatible BJP (if it clears my fork) is sometimes tempting too for the road bike, but then I might as well ride my gravel bike with the bigger tires!

I decided to bite the bullet and ordered a pair to see for myself. If anything goes wrong, I can always put the 25mm Pro Ones back. Will report the actual width when the wheels are built in a couple of months.

Be careful, I had a tubeless BJP blow off a RRU35C02 *after* a fast descent and have been running them with tubes since. Sub 3 bars pressure, no warnings.

Yikes. Glad you are ok.

So this was after they had "blessed" the BJP for tubeless? Wonder if others have had problems with the BP or SP tires blowing off. I run both of these around 42/46 psi.

Yes, bought them as TL ready or whatever Jan calls it. IIRC I wasn't the only one.
