• TT'ers, I have a question, I'm looking to build an '80s-'90s machine for fun, racing about the Chilterns and Henley where my folks live. Good to get out of London right?

    Whilst I'm not concerned about the components being period correct can someone advise me on groups which would be suitable or at least a direction I can investigate?

    The frame will have downtube shifters, single ring most probably also. I was looking at Dura Ace 7700. Thoughts?
