The seatpost on my Dawes Galaxy had been stuck for over 2 years. I couldn't move it and neither could the bike shop. At first I wasn't too bothered but when I was fitted for my new bike I realised that the saddle on the Galaxy was too low making it less comfortable and inefficient. I searched the web and methods of sorting it looked rather extreme and risked damaging the frame. Then a club-member suggested the Seatpost Man. He (John Lee) is based in Chorley, Lancs so not local but on the way to the North. He was very good at agreeing a time to suit me. I left the bike with him and in 2 hours it was done. Cost £60 but cheaper than a new frame and the bike is now a pleasure to ride (as well as being easier to pack up for touring!).
I'd definitely recommend him to anyone who has a similar problem. And what an excuse for a trip up North - cycling or otherwise!
