The wobble test on the freewheel was done as you suggested & it does wobble about a bit , so it will be a wheel set change & fit a cassette. The bike is fitted with btwin's own tyre brand which is supposed to have puncture resistance. No idea if it really is what is says, will take them of to have a look when I get the Taylor's replacement. The derailleur will be next on the list. Once again thanks for all your help & suggestions
