It's in the photo!! Too bad the inner ring is always green... Would have preferred Red or Black, but I guess it won't really be visible once mounted.
Well thats it fitted and all play from the shaft has gone. Should make a difference when shifting but considering my exhaust is laying in pieces it will get tested later. One point to note is the capscrew it was supplied with would only have made up a couple of threads at most. It was far too short so i fitted a different one to give the same make up of thread engagement as the OEM bolt, which was around 1/2” The white seen between the interfaces is surplus ceramic grease that I packed the roller bearing with before it was fitted.
I would really love to see an engineer's report displaying how much 'flex' these supports reduce. We're talking a shaft of approx half inch mild or tempered steel over a distance of 2 - 3 inches. How much 'flex' could there possibly be? Might there be a case for thinking that these supports merely provide the rider a placebo effect of more positive gear changes? Perhaps @Jez might be able to illuminate?
