I have an old Dawes, and I mean old, like 30 years or something, that's ancient I'm sure of it. People tell me I should bin it, but I like it, and it aint all bad surely. I'm planning on buying some Paul Hewitt wheels and getting the frame renovated and repainted by Ellis Briggs then I'm going to have to refit the bike with some decent components. Unfortunately the older kit on it has seen better days. So, I figure instead of scrabbling around for all the right kit to bring it back to it's heyday, I'll drag it kicking and screaming into 2010 and all that entails in terms of a new drivetrain. So, (don't worry I'll get to the point eventually, just be patient) what are my options and what on earth do all those Shimano codes and bits mean (Tiagra, Ultegra, Deore, XT LX QR FP YU, yeah ok I made some up)? What do I need for touring and the odd blast through the countryside?
