I Just bought a pair of TL 25mm in Belgium during a business trip… it was probably their last… i did not hesitate to splurge 140 euro for the pair.

Not a terrible price!
Delivered today:
28c front and 32c rear for a gravel event in two months. It’s CA Central Coast so dirt roads with some rock - Tarmac SL7 and wider tires.

I’m entertained to find this thread. I don’t understand why anyone would run anything other than Continental GP 5000 S TR. I guess a few people have had poor experiences but I think those are pretty rare. They’re a great balance between rolling resistance and puncture protection. Real workhorse tires, racing or training.

since the gp5000 TL cannot be bought anywhere anymore. finding them at this time even at full price is a good deal imo.
I use them and they are great but I think some folks have been put of by the fitting experience with the 5000TL’s and 5000S TR’s I think. I just fitted a pair the other day. I tried first (back wheel) inserting the sealant first and then fitting it was a bit hard to get over the rim when I couldn’t push hard down into the rim for worry of sealant escaping. Once done though it seated 1st time with a track pump. With the front wheel I fitted it dry so I could push the tyre down into the rim well though and it was comparatively easy. The only problem Stans race is a bit too thick for a syringe but I’ve solved that with an old tubeless bottle that I can use to inject it pausing a couple of times only to unscrew the nozzle and un clog it (with a syringe and hose I have to stop often and cant unscrew the nozzle). It also seated first time with a track pump 
I think thats the trade off with tighter tyres/ rims, they are harder to fit but easier to seat.
I’m not sure that putting Stan’s race through any kind of small hole is a good idea, the bigger chunks just won’t get through and those are the bits you need to seal bigger holes.
My approach (and I use both Stan’s Race sealant and Conti GP5K S TR) is to get ~80% of the bead on with no sealant and with both beads nicely pushed down into the centre channel. Then pour Stan’s into the tyre through the bit of bead that isn’t fitted yet. I use a little plastic measuring beaker/jug for this and make sure the sealant is well shaken before measuring it out. Then fit the rest of the bead as I normally would, the sealant stays at the bottom and isn’t going anywhere.

Its not ideal but Im using the little 60ml Stans bottle for Stans Race for road side repairs apparently. I’ve tried what I think you are suggesting in the past too, but with the Stans bottle, it was maybe me and the lack of space in my corridor but I found it rather messy (although I think it would have worked with these new rims (Scribe and the 5000 S TRs )
Two words. Tan wall.
The Corsa Pro just look so incredible. And they’re lighter. And from reports, more comfortable to ride on. I’ve run every iteration of the GP (4000, 5000, TL, S TR). They’re amazing tires. But I just picked up some Corsa Pro because I prefer the look of the tan wall. Also have run the Challenge Criterium RS. Also tan wall. And a good 40-45g lighter per tire than the S TR.
Case in point.

One reason - a brief inventory shortage and high impatience!
I rode Contis for 10+ years. loved them and was never going to switch. But for a short period in 2021 when I was very keen on switching to tubeless, Contis were hard to find. That’s how I ended up with Schwalbe Pro One TLE. They are easy to mount, ride great and have been flat free. I just bought a 2nd set so I guess they are my tire of choice now …

Very interested to see what you think of these vs. the N.EXT and maybe GP5k TR regarding puncture resistance and rolling resistance in the short term plus wear in the long term.
I switched from N.EXT (34mm) to GP5kTR (32mm) and frankly very happy I made the switch. Rolls faster and IMO puncture resistance is just as good if not better.
Well I’ve had ‘can’t plug it’ issues with the GP5K TL, and frankly, all the top fast tires (S-Works, Schwalbe Pro One, Zipp Tangente, Pirelli P Zero Race, …).
The S TR have less puncture resistance than the first generation TL. I had a set of S TR tires in 30c and they were extremely difficult to mount, on 3 separate sets of wheels. Thats a vote of no confidence of putting a tube in on the road, or Air-Liners when installing. Not interested in trying another set until Conti does another iteration.
The N.EXT roll nearly as fast, and from AeroCoach data I lose about 9W versus the S TR. Better road feel. My fastest tires are 5000 with latex tubes, and when I use the GP5000 as a daily tire, I flat about once a month. The GP5000 has more puncture resistance versus the S TR, and about the same puncture resistance vs N.EXT. Road feel its not even close - Vittoria and Specialized for the win. Traditionally I have gotten about 2000 miles on GP4K and 5K tube tires. The best mileage on tubeless was the first generation S-Works tubeless.
I don’t think it’s rolled out to the states yet but I think the intention is to. Pirelli are recalling in the UK and Europe their 28mm Tubeless P-Zeros that have been made since March.
That’s my experience. On my road bike currently is a TL on the rear and I can’t recall it having a sealant spray and the tread doesn’t look cut up. Where as on the front is a TR which has done circa half the mileage, under less load too, has sprayed quite a few times and it looks cut up in places 
Its also got a side wall p’ture that will hold 60psi no problem but at 70psi after circa 30mins it suddenly goes hiss! I never had that with a TL.

Less than 400 miles I’ve had 6 flats on Bontrager R3 Hardcase Lite TLR’s. Even with sealant that had particles in it they wouldn’t seal back up. Pulled them off and put Conti GP 5K S TR’s on. Weren’t that difficult to put on, used a tire lever and a bead jack and went on easily (much, much easier than the previous GP 5K TLR’)…
I guess it makes sense to have less puncture resistance if you can rely on sealant.
A GP5000 TL plus silca sealant saved my ride a couple of weeks ago at the cost of 10psi and some sprayed sealant.
Looks amazing either way! But, the GP5k S TR comes in a tan as well. Not as white as the Pro which I think looks better.
I think what people will find is that while the Pro is more supple it will fail and wear quicker. All for a couple Crr watts. They are lighter for sure but, again, there will be a tradeoff in durability. nttawwt.
I’m still hesitant to buy a set so let us know how they wear. I’ll try anything once. Until then I’ll keep rolling the 5k’s.

I wanted tan walls. GP5000s where hard to find so I tried veloflex and these turned out to be great tyres, very supple, grippy, lighter and perhaps in the real world even faster because of the suppleness and according to bicyclerollingresistance.com they are even more puncture resistant than the gp5000s
First rides done on GP 5000 AS TR tyres. They are not bad; actually they are very good.
I got the tyres for autumn and spring rides. The autumn meaning riding on bad roads in rain and in darkness; spring is almost the same, except that the roads are covered with sharp gravel in many places. I have previously used the standard 5000 S TR , but I hope the AS will be more robust in those conditions.
I was very surprised how comfortable tyre the AS is. I thought the ride feel would be close to the old GP 4-season, wooden and rough, but that is not the case. The tyre feels very much like the standard S TR, although a bit heavier. On my local roads the weight difference is not an issue, as we don’t have any real climbs here.

I love the GP5000s… But, I’m fed up of how hard they are to fit. Heaven help I hit a pothole in backa beyond and can’t insert a tube.
