They're widely available from the usual dealers in Europe
Didn't find them in bike24 (which usually has the stuff at least listed) that's why I was wondering. Edit: seems r2bike has them, as "limited edition" indeed :D

Just ordered 2 5kTTs. Too bad they aren't available in 23mm. Not sure how they will perform aero wise on my aerocoach titan wheels.
Same wheel here. No worries, the 25c S TR and TT are tiny, pretty similar to the GP5000C 23c. No penalty there (which I double checked with AC).
Thanks for the info. Really can't wait for BRR to release their rest now.

Anyone have issues on the sidewalls with these? My older ones pretty much fell apart

The sidewalls still get a bit ragged. It's the Conti way.

I've got my vote in on BRR - hopefully others here are voting as well - but Aerocoach already has them on the way and so hopefully should be testing and posting soon.

I expect flexible sidewalls are a large part of the reason Conti's roll so well.
I've never had one let go in 10s of thousands of kms though I've read of plenty that have.
Stopped using them at the price they are however.
I love tubeless and am staying tubeless but there are others that are less ridiculously priced.

After getting these re-taped twice (two different bike shops) my set of STR's are still losing a lot of air.

Anyone else experience similar issues?

I have them on two bikes. I lose about 4 psi a day. If you have a large leak try putting the wheel in a bathtub. Also make sure the nut on the valve stem is tightened properly.

What sealant are you using and how much?

Stan's

Not sure on the amount used as my LBS re-taped and put in the sealant.

Would a GP5000 S TR with a latex tube inside be faster than a regular GP5000(not TL)with a latex tube?

Isn't that with 20ml sealant?

It's going to be quite different with a standard 80ml sealant no?

I don't even put 80mL of sealant in a 35mm tire, let alone a 25-28mm tire.

Also if we want to run an apples-to-apples comparison, we'd put in maybe 30mL of Orange Seal, let it coat the inside of the tire, then suck it back out with a syringe. Regular clinchers with latex or butyl tubes don't have self-sealing properties, so the liquid sealant isn't needed in a prepped tubeless tire either. That flat-prevention is a bonus in this case.
