Well sure, all bikes can do all things, right? Just you might have more fun or less fun depending on which bike you've picked. I fucking love riding that shitty CX bike through sloppy fields and canal paths in West London after it pissed it down but would I want to ride Badlands on it? Fuck no.
My Marin 1x1 goes off road all the time and is more than fine!!
I guess the riding you do is different to my pootle round the woods!
