As I said above I am tempted to go singlespeed especially as at the moment I only have the clunky chunky 7 speed kit which came on the Hardrock and it's been a while since I had a lightweight xc bike.These are great frames to ride so certainly worth your time to restore. Can't do links but I recently posted my SS M2 here.
