Can someone give me the diameter of the chain stays on a RC2?

I ordered a RC2 last week. Waiting for it to be delivered. If there's anything that freaks me out when getting a new bike is having the chain slapping down on the stay. Chipping the paint and getting oil on it. I typically install a Lizard Skin protector on my bikes. Since I'm waiting around for the bike I figured I'd go ahead and order the Lizard Skin and have it ready. Since I don't have the bike I would like to know the diameter of the chain stay so I can get the correct size.
