Bar end weights 5th gen

[Ntolerance]

Evening. 

 

I tried  a search. Came up empty. 

Is there a way to stop the bar end weights from spinning?

 

i really like bar end mirrors in addition to my stock mirrors. On every bike I own honestly. All three. But on my 5th gen screwing them into the end weights allows them to turn. I can unscrew the weights and take them off but the insert still will turn regardless of how tight I make the screw. 

 

Any thoughts ?

They shouldn't spin. There's a metal angled collar piece that fits inside the handlebar tube and the inside part of the end weight grips onto it. As you tighten the screw it locks it in place. The part can be purchased and replaced. If you have a look on the Lings website you can examine the parts fiche and then order one from your local dealer Part 10 on the attachment is the piece I'm on about..
