Can I turn this into a bike for cross? What makes the most sense? Single speed? Swap the V's for Canti's, add a drop bar and levers and lose the old 8-speed? The sloping geo is hard to shoulder, but it's doable for a few races, I'm new at cross and don't want to buy another bike just to try it out a few times. What do you all think? How would you rebuild this?
