I bought this last year for a very short lived dirt drop experiment. It cost a pretty penny and is just sat in a drawer which is criminal. It's a 22.2 (1" headset) quill, with a 31.8 clamp size. Its 90mm long. It has some scratching to the bottom.and a tiny mark on one side, both of which don't effect it in any way. I'm asking £60 posted, which I think is fair given the scarcity and price brand new. Always open to offers though. Cheers!
