If you ride in rocks don't buy this tire, its not much of a deal if it only last two rides.
The side knobs get ripped off easily in rocky terrain but it works awesome in sand/mud if you ride in that a lot.
The xcms, xcmh, scorpion pro and extra X are much better allround front tires if you want a Pirelli, the side knobs are bigger and don't get ripped off.
I run the extra X for this reason it has a little less bite but it holds up to rocks, it sucks to have to replace your front tire after one or two rocky rides.
I prefer the kenda Washougal front tire tho, its better than the extra X in every way and cheaper to boot, im getting another washougal when my current extra X is done.
