My joy at recieving the new bars quickly waned once I tried to fit them to the top yoke - the clamps would not sit over the bars, likewise the clamps for the controls will not go over the bars, neither will the twistgrip.
A quick check with the Vernieer shows that the O/D is anything between 22.3 / 22.5 mm with my old bars measuring just shy of 22mm - and everything fits OK.
I know that the bars are nominally 22mm, but it seems that these are outside of tolerance.
Even if I try opening up the clamps for the controls (which are alloy) they will not open up enough - I think they would probably break before they did, even if I could get the clamps on it would be no good as the twistgrip will not go over the bars.
All packaged up along with an explanatory note to the vendor (who has a good rep), lets see if he earns any "service stars".
