I rode Cycle Oregon last Sept on that exact combo except 7-speed. Sweet, sweet shifting. My standard forever (starting with the TA Cyclotourist, then Avocet, then Sugino was 52 or 53-42-28m then 24. Recently the 52-42 has shrunk to 50-38 and the like.

Question, [MENTION=124730]SJX426[/MENTION], what are the BCDs of that Campy crankset? I could go out and measure so don't you but if you know off the top of your head, TIA. I need to start ramping down those big rings!

Edit: beautiful bike!
