On ebay it is described as 330mm and comes in 5 colours. The accompaning alloy mounting bracket opening (in my case) needed to be slightly enlarged to fit the frame tube.
I got the same damper and got a mate to machine the mounting bracket to a slightly larger diameter and it fits the frame perfect. I'm pleased with it and it looks great. It's adjustable too.
