Mine were very difficult to mount the first time. And I didn't have a tire jack at the time. On a recent ride I got a flat in the rear wheel. Pulling the tire off to repair the flat wasn't too bad. Remounting is was easier than the first time but still difficult. I have about 700 miles on them so far and they are holding together nicely. They ride nice but I'm not sure I would buy them again. Nothing really special about them that I can tell. Then again, I am a barbarian.
