Saw one of these after trawling around the threads and looked pretty good so inquired with Jaws m/cycles.[ by the way I have no interest or discount deals withthis bike shop or conections just that I cant remember which thread Isaw it on .]The geezer was really helpful and posted one off as soon as he got the cheque. Its been made from a solid lump of stainless steel, nice and heavy so should nt suffer from any vibes , It took all of half a minute to fit,a real quality piece .
