Seat Post Size? Avanti Pista Pro 2005 model.

Help. I need to buy a seat post for my 2005 Avanti Pista Pro, which is a 2005 model, but I cannot for the life of me remember what size the old post was… (this Pista shared a seat and post with my 2007 Santa Cruz Superlight which I sold a few months ago)… I tried googling it but have failed… Is it a 30.9? Help!

Why dont you get a set of vernier calipers and measure the inner diameter of the seat tube.

Otherwise take the bike or frame to a bike stroe and they will sort it out for you.
