IME lighter tubeless tyres have been pretty susceptible to damage anyway
That's exactly why I stopped riding tubeless, back in 2016. I experienced too many flats, on Hutchinson (Atom Galactiks, Fusion 2's and 3's and Sectors) and Bontrager tires (R3's) to merit continuing with the experiment. I especially grew tired of wiping sealant off my frame. I'll stick with the clinchers.

I get far fewer punctures with tubeless than with clinchers and wiping off my seat tube takes seconds. I use Galactiks and other light tires on shitty California roads. Your narrative bores me.

WRT a lighter “TLR” GP5K coming out, I doubt it. Despite the black color, as 2lo8 points out, the GP4K and GP5K are sidewalls are non-vulcanized cotton thread. Without the butyl layer, these tires would weep sealant like the Panaracer made Compass tubeless-ready tires.

Thead about a new tubeless tire becomes a thread about how tubeless doesn't work -- never change Weight Weenies, never change.

Meh, Conti super-reluctantly gets round to putting out a tubeless tyre. Not swapping.

(Yeah, unfair, I just find Conti a bit boring, like Canon cameras, but maybe this is a really good tyre, who knows.)

Interesting that the tubeless version has a little flap to lock into the tubeless bead lock channel (not sure about the exact technical term).

I hope that 25mm actually measures 25mm.
Haven't measured with calipers yet, but just mounted a set of 25's on a 21mm inner width wheelset and they're definitely more narrow than the 4000S II so I'd say they are true to size. I was also able to mount them pretty easily without tire levers

How about the ride? I read on one of the articles that they're "stiffer". I wonder if that translates to a harsher ride.

If they are stiffer, it's definitely down to them trying to fix their prone-to-failure sidewalls. So I would not be surprised if that were the case.

I'm totally waiting for the day their 28c is not too hugely oversized. And weight suggest that the 28c should shink.
In the 4000sII generation, their 23c and 25c are really close to each other in size. But the old 28c is way way bigger than both. Now that they have 32c as the biggest size, it's time to dial back 28c to where it should be.

their specified weight:
size: 4000sII vs 5000
23c: 205 vs 200
25c: 225 vs 215
28c: 260 vs 235 (big jump of difference compare to other size)
32c: non vs 290.

Actual weight of a sample 4000sII based on https://www.bicyclerollingresistance.co ... i-23-25-28,
23c actual weight is 203 (correct)
25c actual weight is 215 (10g lighter than spec, match spec of the 5000)
28c actual weight is 267 (7g heavier than spec).

25mm as the smallest size won’t work for many seeking maximum aero gains. Shame, I would have tired them but need a 23mm.
This. I just mounted a 23/25 Pro One combo because all my wide-tire wheels are tubeless, and I wanted the aero wheelset to be too.

I just mount 25mm (measure 26mm) gp4000’s to my mavic r-sys slr superlight, 19.5mm wide, super-un-aero fat carbon spoked, box section wheels. They are like the bike equivalent of going down a river in a paddle boat. They do just fine in cross winds however, and are respectably light.

I think they also offer an aero advantage with the wind at your back... as there is more surface area for the wind to push on.

These wheels are guarantted to make you 2km/hr faster... when you put on proper aero wheels.

Where did you purchase the tires? I'm in Orange County as well and would love to try a set.

MSRP for these is $80 for the clincher, $95 for tubeless. For reference, officially the MSRP for a GP4K is $75, so they probably won't ever sell for that much...hopefully?

They could sell at that price for a while until it's widely available, i guess.
EDIT: already found a website that i can order it from at $79. I'm very likely not purchasing one until price go below $50 though.
