We need an enthusiastic user of GP5KTL/New Spesh TLR to try these out and draw a comparison. And of course, we also need BRR to give us figures. Possibly, all this before I will need to replace my rear tyre..
LOL. I went from the old newest Pro Ones regular to the 5000GP TL, both in 28. I felt the pro ones had more feel at the limit but am getting used to the 5000GP TL with 900miles on them. over all they are a great tire. I too am interested in trying out the new offerings from Specialized and Schwalble. I don't think either one will roll better though.
I’m willing to give up some RR for grip.
Spesh TLR will definately not roll better then 5000TL.. new schwalbe has a chance but will come up a 0.x watts short.

I'm also happy to swap that little bit of RR for grip. And a tire that doesn't fall apart *cough*5000tl*cough*

My concern with the way these are constructed in pictures (https://bikerumor.com/2019/08/23/new-sc ... less-tire/) is that there is a 14mm puncture protection belt, then a gap, then a triple sidewall. In theory the thinnest and most vulnerable place for this tyre is where that 14mm belt ends and before the sidewall begins. 14mm is not a hugely wide contact patch, particularly if you hit a bump or run lower pressures. So I can see this puncturing pretty easily in those circumstances.

My second concern is this whole thing with Souplesse... What kind of marketing bs is that?!?

I agree. I’d also give up some RR for grip but tbh on my Corsa Control I used to replace a rear GO5000TL I didn’t quite feel any improved grip but it did feel noticeably slower.

Are you referring to the "strings" that seem to peel away from the bead of the 5000TL? I've seen these on a number of occasions, and my first reaction was to worry that the entire tire was ready to unravel as one "string" led to another, but in practice, it seems they appear somewhat infrquently, I yank them off, and there don't appear to be any real consequences.

Still not ideal, and something I would like Continental to fix. Has anyone heard any commentary/explanation from Continental on this "string" phenomenon?

I think it will be “fine” because that section without the extra casing layer still has a thick tire tread that won’t wear significantly.

Funny enough, I think that's actually right where I punctured over the weekend. I had to lean by bike over just about 10 degrees in order for the sealant to pool up and seal. Some coincidental bad luck!

Still not bothered. They ride very well and they sealed and I kept on my merry way.

Just measured my new 28c tires on Roval CLX 50 at 28.3 and 28.5 mm, which is surprisingly narrow considering the rims are 21.9 mm wide internal. Will surely stretch a little, but these v2 Pro Ones are narrower than v1 which I have a lot of experience with.

Oh, that is very interesting. Here I've been thinking I'd get a fatter tire out of swapping to CLX 50, thanks to them being 2mm wider internal, but my 25s are measuring about 26.5 on the Enve.

I'm actually a fan of the label matching closer to actual width. Makes it easier to plan :)

That's one part of the new ETRTO standard, having labeled sizes be closer to match real world sizes on more modern rim widths as before it was all over the place, people in the know knew which tires were bigger or how to find the info but for many, it lead to suprrises, pleasant or not. Continental GP5000 also use the newer sizing so you don't buy a 25 if you really wanted a 28 like before...

Do you have access to the new etrto tire width measurement standard, Dan Gerous?

For road tubeless the new standard is a 19mm inner diameter rim, so going up or down with ID will incur a reduction or increase in tire width and height.
The tire sizings have also been updated to measure accurately on 19mm internal road rims.
https://bikerumor.com/2019/08/23/new-sc ... less-tire/

However, with my initial impressions using the 2020 Pro One TLE the 28mm gets smaller at a higher rate on narrower ID rims than gets larger on wider ID rims. At 80 psi on a Giant SLR1 17mm ID the 28mm Pro One TLE measures ~26.9mm wide and 24.2mm tall, while on a Bontrager Aeolus Pro 5 19.5mm ID it's ~28.1mm wide and 24.7mm tall, and on a Reynolds ATRx 23mm ID it's ~29.2mm wide and 25mm tall.

Will re-check later tonight as they're on the Bontrager right now.

The owner of my Specialized dealer told me yesterday that the new ERTRO standard is dead. This is due to manufacturers being unable to agree upon a narrow (and therefore precise) enough specification. Reason is because narrowing the specification will render many rims and tires immediately obsolete, requiring expensive redesign. This would be painful for some larger manufacturers, but a potential death blow for smaller companies lacking capital for such R&D, retooling, and disruption of sales of current offerings. Understandable from a financial point of view, but disappointing as a customer.

I’m gonna take that with a grain of salt. Currently there are loads of rims and tires on the market which are way off the old ERTRO’s spectrum and still seem to be selling well.

In fact, I’m seeing a new business opportunity there. If the new ERTRO is consired as something ”special”, anything carrying that badge is ready for a larger mark-up. And even better if rims and tires are sold as ”ERTRO compatible only”, because then everybody ends up buying new tires when getting new wheels and vice versa.

However, I can imagine the new standard to be so tight that only ones ready for such accuracy in manufacturing will be the big players, and they won’t mind manufacturing even lower tier items at high accuracy, as eventually high quantity will produce profit.
