Ok, sounds like it might work out then. I'm in Hamble, so probably not far from you! You could come and have a look, or tell me how you want me to measure the frame as I've always been confused by frame v wheel sizes!
Are you still looking? I'm 5' 6" and have a US bought black Bear Valley. Rust coming through the frame a bit, but all in working order apart from one of the shifters. Love this bike but no space for it with a couple of kids now.
I've got a 1994 Bear Valley, still ridden regularly, rust coming through the paint but not structural. Everything is original, only thing that needs repair is one of the shifters. Would this make a good project for anyone?
