Cheers Daz, I've already got a 631 frame made by a bloke in Coventry about 12 years ago. At the moment it's sat on the turbo, but I'm sure that's a waste! My normal roadie is an alu Trek. It's a good bike, but on the crappy roads around here it's very harsh at times. I might take it out for a spin next week, I'm not going to use the turbo in the summer anyway!
