Yeah, I've got one. It's ok so far. Waited three weeks for delivery and still nothing so I contacted the guy again and had a moan and he sent one out special delivery and it turned up the next day. It looks a weak and spinally clamp but I'm 15st and have used for a while and it hasn't budged. You can sand blast it too to match the satin TI frames. Word of warning though. If it does give way, it's going to core me. The top of the post with the clamp removed looks like it's designed for disembowelment. Will probably buy another one at that price though. Bargaintastic.
