Trek Madone Seatpost width

[Mongol_Waaijer]

I have lost the seat post clamp for my old Trek Madone frame.

I think is it a frame from 2007 or 2006

Does anyone happen to know the seatpost width? Is it a 27,2mm?

The reason I ask is because the bike is at home, I am at work, and bike shop 100m from office....;-) would like to get the clamp today if possible

Going on memory here but I'm 99% sure it's a 27.2mm. Would have come with about 20mm of offset originally, too.
