How diificult is it to swap back? I'm finding lots of "forward" bikes, but I want mid. Also, if the owner bought it that way, what parts would I need and how much $ ?
You can swap back to mid controls easily. Based on posts here, most people who change the controls are going from mids to forwards, so you should be able to find someone here who has a set for take-off mids that they would swap for your set of forwards if you post up a request.
Thatis an easy swap. I have a buddy that went from forward controls to mid. Pretty simple, and as was said, you can probably find the hardware for mid controls in somebody's "take off" parts pile.
