Aside from using a pair of calipers is there anyway to find out what seat tube diameter my Gemini has?

I've been looking through the cannondale webpage and can't find it. I'd like to order a longer seatpost but I want to make sure I get the right diameter.

Call the shop you got it from or call any c'dale dealer.

Thanks everyone. Sheldon Brown is correct. All Cannondales except a few models in the 1980s used a 27.2mm seatpost according to a Cannondale rep I emailed.
