Unfortunately the ones you gave me broke after 1 ride the ones I’m using now I got off Amazon and seem to not be as brittle but maybe already failing. The one on the gravel bike has been problem free so it might just be this one is getting wonky.
are you crashing with them? since i was mostly using them for helmet mounts and they survived pretty well in that environment(i only remember breaking one of them during a ride), i find it hard to believe a handlebar mount would be a harder life.
