Thanks Campag4life,
I feel very comfortable with the size of the bike with the drop bars, just shortening the stem 2cm would finish it off.
I have been told at a bike shop that I would be faster on a "made for purpose" road bike frame, but I don't believe all I'm told at a bike shop as they are trying to sell some product! I seem to be able to keep up on a club run so I think I'll leave as is.
Going to get a winter/rain road bike so that will be give me a different perspective.
Thanks again for the advice. Much appreciated.

Dave
