Well guys... The old FSR has been good to me and taken a beating well beyond what it was ever made to take, but today it's younger brother finally arrived!
I don't think it is a big hit as such but it does look as though a set of big hit seat stays and linkage has been fitted to allow a disc brake to be fitted. Need better photos.
what year model did you track it down to. I do think its a bitsa as the cables for the disc's do not seem to fit the bike, they are held on by cable ties.
