im 5'10" i have a road bike which has a 57 tt i find its a little too big, how about mountain? (i suck at sizes for mtb, im only slightly better when it comes to road bikes. . .)
For the sizing of the time you're about right. If you were buying a modern bike then it's a touch large, but for 1988 this bike is like a tailored suit. Made of metal. And painted red and white.
If you're local you're welcome to try it for size.
If you're in/near Bristol (from your other posts) we're heading down that way in a couple of weeks to see friends. Could pop it in the car to save on postage.
I'll weigh it (assuming I can find scales that can cope with that kind of trauma) and get a quote. Do you have a private email? I'll send you more pics of the surface rust as it's not coming up very well in the photo above and I want to show this honestly.
