Can I do this on a mountain bike?
I've never done CX ever. I just want to do one race, our team is putting it on. I swear just one! I've got an old Durango made Yeti ARC XTR with a solid fork and road cassette and like 1.5" or something tires can't recall offhand.. Are mountain bikes legal? Is it like XC where I need to sprint like crazy in the beginning to get a good spot? I'm a "3" on the road. What am I in for?
