Fitting bar end mirrors..

Struggling to fit bar end mirrors onto Renthal bars.. the expander thing doesn't seem to want to expand enough inside the tube, so when I attach the mirror section and move it a little, the whole thing becomes loose and starts to spin.. 😕

you need to tighten the expanding part outside the bar end just enough to make it a tight sliding fit. once inserted into the bar end it will grip and let you tighten.

I have Renthal Streetfighter bars (inherited when I bought bike). I have bar ends on mine.

I went for the ones that go over the end of the bars & you tighten the outer bar to form a snug fit Add x amount of plastic inserts to make them fit snugly. You might find those fit the Renthals a bit easier.

I have straight rental bars on mine with bar end mirrors, came with the naked curvy top yoke I fitted to help out with my lower back & wrist issues !
