Cheers for all your help guys. Went to my local LBS and the first suggestion they offered up was the Compact route.. Interesting that as I would then not have to swap over the shifters. My ones are definitely only Double which is a right bugger. Going to have to sit down with a pen and paper and work out the gearing with a compact and a different cassette. Would I need to change my front mech with the compact chain set?

Cheers Again.
