This tire came with my Jamis XC Sport and have been riding them for over a year. This was my "beginner" bike and so some hard riding, crashing and hard knocks came with the territory. Overall, I think its great. I've had only one flat and it's more my fault than the tire as I lowered the PSI to about 28 for the rooty trails of Oleta. The tire is still running strong with plenty of tread life, I also do alot of road rides so this is surprising. I'm giving it 4 stars cuz as a Novice rider I'm convinced there is a tire better out there. Or, I've just been spoiled by the folks over at Jamis. I'm converting to tubeless so I can run lower PSI's so I decided to go with some new tread. I may end up missing these Geax's.
