Set up tubeless, took a couple of days with orange seal to properly. The carcus is very porous. Also rides a little rough for a 25mm tire. Even at only 80-85 psi(I weigh 185)Feels very fragile. Measures a little under 27mm on a 19mm internal width rim. So the good- is the fastest and the lightest tire I have ridden. If you have a t t bike this is the tire for you.
Though it was a bit of a struggle to get these mounted, once on they are amazing. Fast and smooth, only downside is i dont feel they have quite the same grip in the corners.
Pricey but that's new tech for ya. These ride as good as Corsa Evo's and I have confidence in cornering. I notice they feel thin, but that's probably in my mind. I can't comment on longevity but so far so good, no visible cuts yet. Mounting is easy and the fact it's only a 23 is good with me, I prefer them anyway.
