I agree they're great...and with a latex tube inside of them, one isn't going against the manufacturer warnings, and with no practical downside as opposed to running them tubeless IME.
But...it's your skin and teeth you're risking by running them tubeless...so who am I to judge?
Heck, depending on the results of my testing of the TLRs, I might just try my Pros set up tubeless as well ;-)
following up on this, i've been trading emails with challenge, what they said about the Pro is that it's as "tubeless capable as any tire we make, including our TRL." i asked with specific interest in blow-off and burping.
their concern is sealant related to the latex construction inside the tire. as luck happens, i've been using the sealant they "have the most confidence in," which is caffelatex. they are also interested in the amount of bleeddown overnight with this tire, and i'm going to do a little study on that for them, but my sense of it is that it's less than what i typically get from a latex tube in a standard tubed tire (but that may be due to the fact that i only use latex tubes in higher pressure road tires).
VERY interesting...thanks for the follow-up on that. It sounds like a non-ammonia based sealant would work best...I may just try some Orange Seal in one of mine.
Yeah...IME, "bleed-down" in latex tubes is much less in gravel and MTB applications, mostly due to the lower pressures involved. That said, tires I've set up tubeless with sealant seem to "bleed down" even slower...
Now we just need to convince them to create a version of the "Pro" models with only a single, or no, puncture layer :-) THAT would be a fast tire.
i'm naive to all of that. it seems to me - tell me if i'm wrong, please - that this tire, the PRO, is sort of a gravel version of the open tubulars we get on road bikes. this is a 260tpi tire and boy that seems like something i want, isn't it? it's almost like a big beefy cotton tubie, just with somebody cutting up a latex tube and gluing it onto the sidewall? (which is why they like the ammonia-free sealant.)
they're really interested in what sort of gravel i'm riding on, how sharp, and i think it's to see how that sidewall holds up.
"Open tubular"...it's EXACTLY that. Like I've often said, good casings go a LONG way towards making a nice tire.
If they need more data on riding on sharp stuff, just tell them to get in contact with me.
I ride my GG Pros on everything and including rocky MTB single-track trails. In fact, I just got back from a quick ride at lunch where I took them on a local park's single-track trail that I usually ride my MTB on. How well they roll as compared to a typical MTB tire is easily "palpable". IME, the casings hold up VERY well to scuffing and "sharps". I haven't punctured/sliced/flatted a GG Pro yet. I just wish they made a Pro model just slightly wider (~40mm) than the current 36C max.
i'll pass this along. i know they want feedback on how this sidewall will perform. i went from 40mm to 38mm to 36mm. panaracer to g-one to trigger pro to this challenge PRO. what i tried for in each case was a narrower tire that would ride better on the road but with enough traction, and so far i haven't found that i've lost anything. i'm riding this tire with 35psi most of the time, i'm 170lb, so far so good. famous last words?
I've been wanting to convert my gravel steed to tubeless, and have been running the GG's since I got the bike (Ridley X-Trail) since it came with them.
But my current ones are the RACE version in 38 - will the tubeless conversion work with that tire variant??
FWIW - the Challenge site does NOT have the disclaimer for the RACE, like the below one for the PRO's:
NO TUBELESS & NO ENVE WH.
IF I end up eating it due to burpage, I'll just blame Slowman. ;-)
