OK need to check 'a few' things first...
- any idea what year it is? I'm guessing 1989/90??
- is the steerer / stem size 1 1/4"?
- what condition are the wheels in?
- will the rear wheel take a Shimano cassette? or is for a freewheel?
- the damage to the frame is purely cosmetic? (eg, is the seatpost stuck or anything like that?)
- do you have a matching slick tyre to go with the front?
- do the shifters work ok? (I have some the same which don't work that well)
All the best,
Alex
