Hello The sleeves are too small and need to be widened to 2 mm and then pure beaten with a little force to the handlebars. I have given to the safety of the screw for 2 mm tape on it, it sits really bombs, adjusting. I had thought that it fit right away, but maybe not everyone is the same link. I have these bar end mounted on my E Bike Kalkhoff. The coating is enough even for 2 link, simply goes to the top slide. Who is fit technically, should not buy this bar end and rather can be mounted in stores MfG Gerald
