A friend of mine has a '06 V3 and would like to upgrade to mechanical disc brakes but is not sure what will work on his ride. His budget is <$200. I think all he needs is the calipers/pads and rotors.
Make sure that the hubs have the ability to mount disc brakes. Example:
the website lists the hubs as disc, so you should be covered there.
Second, if coming from a V brake setup, you will need new cables and housing, as the old ones will not be long enough to reach.
My avids cost me $70USD a piece, and cables/housing does not need to be expensive.
