O-yea, I want to add that the old frame was an old 1980 rockhopper and had 110mm spacing for the rear hub and the new frame part is a 135mm so this worked out great! allso chainstays slope down towards the BB but a MTB has a high BB so when you extend that slope make sure you have the room so you dont "strike" your pedal. I picked up the Rackhopper for $10 and put Mich street tires on it that can go to 87psi so the total cost with paint was under $60 until I wanted the dyno hub.
