Question for Concours owners.

[abqhudson]

I have a 2005 Concours frame due to arrive on Monday and I just discovered that I have everything I need to build up the bike except a front derailleur. The previous owner does not know the diameter of the seat tube. Serotta is not open today. Can anyone tell me the diameter of the seat tube for a Concours - stock geometry? I'd like to order one asap. Thanks for any help. If all else fails, I will measure when I get the frame.
