hard to mount; forced to hold down with one hand approx 45 degrees of the tire circle so with the other hand u can get the bead fitted in the well; if not, the tire portion in the well will simply come out and be forced to begin over; it's a real pain; they're more rugged vs t-serve's but u pay the price in sweat and tears to get them mounted safely
I bought the 35mm version. It was not easy to install - took several hours, and only after pumping it up to 60+psi was I able to get it to seat properly on the rim. It is a heavier tire, but the crown of the tire protrudes out so that it isn't completely round. It actually makes the tire feels though it rides faster, perching on the tire crown with smaller contact patch. Good cornering and rides well at speed. I have only ridden it on city streets, on rides up to 1.5 hours. I would recommend this tire - but it feels quite different from the T-Serv Protite, that is lighter, easier to install, but doesn't feel quite as solid as this tire. This tire absorbs the bumps much better.
