I picked up a Marin Muirwood and was thinking about putting some drop bars on it. It'd be more like a cross bike and a little better for long commutes. Is it going to mess up the geometry of the frame or is that not going to be a problem. Also, would there be a problem keeping the trigger shifters mounted on the top of the bars? One final question: would road levers work with my v-brakes? That's the biggest question I guess. I'd like to convert but I don't want to spend an arm and a leg.
