I currently am riding an older Trek 720 multi-track but I feel that I am going to want a road bike at some point in the future, I'm not sure how far into the future that will be though. So the quandary is do I bother to spend a little money like maybe about $200 to make the 720 a better bike to ride longer distances or do I just break down and but a comfort geometry road bike, like maybe something from bikes direct? Or do I buy a frameset and build it the way I want it? I think financially buying a new bike is a better way to spend the money.
