Maybe I'm dreaming, but I have an 04 hollowpoint expert RL, and caught the 4X bug. I'm a light guy (143) and clueless and broke, so I'd like to do it without getting a new bike. Oh, I race XC, too, and am hoping to cat up to expert by the end of the year. So, could I pull it off with just a longer fork, shorter stem and bigger tires? What do you all suggest?
