Thanks for the tips Nanci, everyone I told so far has said that it'll feel so much nippier than my old bikes. The frame that I'm getting is made by Woodrup cycles in Leeds using Reynolds 531 tubing. If you check the website http://www.woodrupcycles.co.uk it is the equivelant of the Giro superlight racing frame. These days to get one custom made by them costs nearly 400gbp. I feel very lucky to have found one by chance, the only thing wrong was a tiny ding on the frame, but nothing major. A lovely blue colour too.
