I’m curious if the tread might be a bit more aero than the Corsa Speed 2.0 and give it more of an advantage. One other thing to note is the wider tread of the Pro One TT TLE. Both tires measured 27 mm wide on the tester’s rim, but the Schwalbe has a tread measuring 32mm vs the Vittoria’s 25 mm. One of my (many) flats on Corsa Speeds was on the edge of the tread. Nary a mark on the tread, but it punctured the casing/sidewall and wouldn’t seal. It’s no secret that ultra thin and flexible sidewalls are needed for low rolling resistance, but having a little bit less of them exposed in the Schwalbe seems like a plus.

Historically, the Pro One TLE has been a solid aero performer. If that translates to this new variant, it seems we may have a new King of the Mountain.
I don’t know. The lower puncture resistance doesn’t reassure me
Yeah. Half the tyres that get discussed in ST aren’t suitable for triathlon and were never designed for anything more than 40km TT on perfect roads that have been swept free of debris the day before as opposed to 180km on some shitty road in bum fuck Idaho.

Slower than a corsa speed… and less puncture resistance. The casing will be too thin to get any kind of meaningful aero trip for aero. So i doubt it will be an aero hero either.

this is the tire kienle’s ridden all year long. i can’t say he’s ridden it in every race, but i haven’t seen him in a race this year where he wasn’t riding it. if it’s gumwall, it’s the pro one TT:

We’ve got one in for testing and I’m hoping to put it in the tunnel against the Corsa Speed as well as the Crr test. It’s really light and thin but given that it’s tubeless I suppose that’s not so much of a problem compared with a clincher only tyre

I’m not so sure Xav, the times that I have punctured racing the TT bike its been hitting stone/rocks on the road or an edge of a pothole, rather than simple small object.
Those bigger slash style punctures just don’t seal with tubeless the way the small holes do. The use of thinner sidewall and tread seems to me to move towards that style of blowout puncture.
The GP5000 seem to me to be slightly thicker with that latex coating over the no tubeless version. Not sure how much extra protection that would give against the bigger style puncture.

Personally I’ve had a good experience with the Corsa Speed, although I change them regularly as there’s a tipping point with their Crr where they get suddenly worse.
The GP 5000 TL is extremely thick isn’t it compared with the clincher - I’ve used them for training over the winter since last November on a training bike and been very happy with them, no punctures either. I did puncture one in a TTT in June but it sealed instantly and we carried on - a good advert for tubeless I think.

Hmmm, that’s interesting because I was using them for as long as they lasted under the assumption that the Crr got better with wear similar to my Conti Supersonics.

Yeah I wouldn’t keep running them past the tipping point (it doesn’t turn them into Gatorskins but they do become slower). At some point I’d love to put exact numbers on it but it’s a lot of work - for the time being we just recommend to swap every 4-6 months and/or always put brand new tyres on before an important race.
They’re going to have to pry my Conti Supersonics out of my cold dead hands. I have used the same pair in races since 2016

So the loss is age-related and not treat-wear-related? On outdoor track usage, I’ve worn 4-5 tires down to the casing over the past couple of years. Next time I do I’ll measure Crr vs. new to try to corroborate.
Are you saying Pro One TT have less puncture resistance than Corsa Speed? where did you obtained this information?
If that’s the case these tires would definitely be a no for me. When I had Corsa Speed tubeless they lasted at most 100-200kms.
The puncture testing/rating is in the link from the original post.
The point I was trying to make in that post is that having more tread width is going to make a tire more puncture resistant. The tread on the Corsa Speed is pretty narrow and it’s easy to cut the sidewall when it’s so exposed. While the tread on the Schwalbe is a lower ‘puncture rating’ it’s still higher than that of the sidewall on the Corsa Speed tires.
When Specialized made their ‘Hell of the North’ tire, it was basically a wider Turbo Cotton with tread that went up 4 mm more on each side (leaving less sidewall exposed for easy punctures). This new Schwalbe has tread going up 3.5 mm more each side than the Corsa. It’s fairly unscientific, but I would think that there’s a chance the Schwalbe could have better real-world puncture protection since they won’t have as much fragile sidewall exposed.
Like others, I’ll probably stick with the latex tube and 23 mm GP5000 up front.

Sorry I should have been clearer - it’s tread wear rather than age, I just meant 4-5 months of TT racing.
