For what it’s worth, I noticed the STR was easier to get on than the TL.
The TL I just gave up and brought it to the bike shop.
That’s my experience as well, but frankly I’m fed up with it. I think they are also much harder on certain rims, including the Giant Sl1 on my bike.
I have a both now - GP5000 S TR in 25 and GP5000 S TR AS in 28. Both on Hunt 50/52mm wheelsets. Very hard to tell much of a difference in ride over and above the basic increase in width and weight. Will be moving my wife to these when her S TRs are ready for replacement as the additional puncture protection is worth the 1/2watts difference.
Have had a couple of what I would describe as catastrophic punctures on my GP5000 S TR, both completely deflated spraying all the sealant out. Both times smashed in a dynaplug and re-seated with CO2 shot. Completed rides no problem and just topped up sealant back home. Riden 1000 miles since the last putting the last one in and they’ve both just become part of the tyre now. Great product for saving larger gashes.
In general the standard S TR is fine for our bad roads too. The sanding of the multi-use bike paths (and even some smaller roads) during the winter makes the life hard, however. Earlier the stuff used for sanding was natural gravel, but nowadays they use crushed stone. So basically every grain of that stuff is a tiny arrow head trying to kill your tyres.
The bike paths (and those small roads) are cleaned after each winter, but not always thoroughly enough, so some arrow heads are left behind. I don’t puncture very often, but in all cases this summer it has happened when I have used a one kilometer long stretch of bike path when heading out for a ride. Luckily the tubeless sealant fixes the small punctures very efficiently.
I’m a Londoner and commute about 100 miles a week, 99.9% of punctures are glass shards. The extra thickness on the AS should really help reduce the number of punctures on that basis.

Currently have been using the Spec Roubaix Pro 2Bliss 32 as a road tire for my gravel bike (2 sets of wheels) which means some mixed surface racing, winter/rainy road training and commuting.
So far have been happy with them, although they are on paper slower than my gravel tires (Tufo Thundero 40s).
As I do use them for commuting I wouldn’t go for something with lower puncture resistance to get less RR.
Which rules out the Corsa N.Ext and GP 5000 variants.
Am very interested in seeing the specs on the new Mondo tire or alternatively a 32c Tufo Comtura 4 TR, 32c Specialized S-Works Turbo 2Bliss Ready T2/T5 or 32c Pirelli P Zero Race TLR (post recall).
Given 2 of these don’t exist (in 32c) and one needs to go through a recall, its likely that the Mondo will be my next set, preferably once BRR has tested them. Even if its numbers are the same as the Turbo 2Bliss T2/T5 in terms of puncture resistance and wet grip with a better rolling resistance than the Roubaix, it should be a great replacement.
I’m happy that the commute isn’t so brutal that I feel I need to run Cinturato Velos.
Haha same, I am even looking at the new GP5000 AR TL as my next tyres. I don’t run tubeless but there is NOTHING worse than punctures…
And they are only 0.5w slower than the regular GP5000 according to BRR.
I get around 1 puncture a year with my regular GP5000s, and thats with around 12,000km a year. Riding in Sweden, Spain, Italy, France etc.

Yea, I was looking at getting a set of those for my commuter bike, which doubles as my trainer bike. Would like to get one of the larger sizes.
Has anyone had an issue running tires around 35mm on a wheel on trainer?
Thanks for sharing this. I ran 28mm P Zero race TLR’s on my road bike and got 8k miles out of them (granted they were shot at that point), and just recently replaced with the same tires since they were fast and shockingly durable for a race tire. Off to check the date on the sidewall…though I haven’t had any issues with air leaking and I never run sub 70 psi even on 21mm internal clinchers. Wonder how many brands have these issues and just never say anything…

No, 45mm works just fine for me
Am I the only one considering converting back from tubless setups to Latex tubes?
I think tubless works great so dont get me wrong on that, but its a mess to deal with and “if” you have an issue with one (puncture, holding air etc) it just seems to become a plague until you replace the tire.
Just throwing it out there, I cant seem to get a somewhat new GP5KSTR to seal even with a internal patch.

I’ve found it can take a day or two of riding and topping up with air to seal fully after using a dynaplug, but then it’s like normal again.

I did not use a dyno-plug but a patch from the inside, truthfully this is the first hole I have had on a tubless tire (that I know of) and its been spitting or pushing sealant past the patch/seal.
What patch kit did you use? I didn’t have luck with the normal tube patch kits. You need one specifically for tubeless tires.
That might be it also, I used a normal tube patch (its all I had).
Maybe I should get some of these for the future as these tires are just way to expensive to throw away.

This is what I used. It’s a little more robust. I have around 500 miles on the patch and no issues with maintaining a seal.

Just get the dynaplugs. Something without the little arrowhead on the plug will let the air pressure squirt the plug back out of the tire.
Edit: oh I actually clicked your link and looked at that. Those would probably do the trick. Probably great for a very good sized hole…but honestly Dynaplugs are just so much easier.

Those Lezyne plugs look pretty sweet. Never seen those. I’ve never really used plugs for road tires. Do you notice a bump where the plug is?
I personally have not used the Lezyne patch’s myself and the only patch I used was the old school Park patch for innertubes.
I have pretty bumpy roads where I live, so even if it did have one I probably would not notice it.
The self adhesive ones? If so how do they cope with the sealant? I carry them in the wallet (they take up no room) but I have had one fail to adhere when it was torrential and I’ve had a couple eventually fail after a soaking a few days before.
