Using the 25 even as my training tire (front wheel) on the TT bike. 2000km on it this year, always going fast, roads are pretty hit and miss, no cuts or punctures yet.
that's great to hear! thanks
my question spurred mainly from a fear of a front flat while bombing 'downhill'.. as my plan is to use it on Alpine situations

Mounting them (as in, getting them onto the rim) is not the problem at all. Very easy. But they are significantly softer than GP5000s TR, and I found it much more difficult to get them filled with air. The 28c was easier for me, than the 25.

How is the TT compared to Corsa Pro in puncture resistance? Based on the diagram on Victoria's website, it doesn't look like it has a puncture belt while the TT does. BRR scores them close though.
Thinking about getting one of these for the TT bike but never went with anything other than GP4k and GP5k before. Racing in Europe, so roads are mostly good.

Anecdotally I’ve punctured my Corsa Pros more than my GP5K TTs despite more overall mileage on the Contis. The only flat I’ve had with my GP5K TTs is riding through a deep storm water gutter at 30mph, resulting in a snakebite.

Sure, I'm curious on the Pro Speeds as well, but the current Speeds already perform slightly better than TT TR's anyway, and are good for 4000+ km (my experience).
Minimum bike categories required in the stable:
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike

Yeah but they are limited to 700x25. It would be nice to get a 700x28 like the TT TRs have.

Does the crr difference make up for the aero deficit to the TT TR?
Based on some other threads, it also sounds like the speed is much tougher to mount, unless that has been addressed.

How do these mount? Are they as brutal mounting as the gp5000?
Considering these or Vittoria.
Neither the GP5K S TR, nor the GP5K TT TR are hard to mount compared to the original GP5K TL.
Hopefully. Those things were absolutely horrendous on my HED Jet Black.
