@SSGT_B and all others
bar end weights :
dears, please NEVER buy ´n use the bar ends with rubber inside bar.
only buy those who have this metal conic technic.
these, instead of the one with rubber, keep fastened all times never the less how many miles you have with em.
i had dozens of times of trouble times with the rubber pieces - they "loosen" and come out by a while !
(caused, i suppose/guess, by the normal vibrations)
Your manner of speech can be quite off putting and it has nothing to do with the translation. Maybe you could try to simply mention your experience with something instead of just telling us “never”. Understand? After all, regardless of one’s experience, it’s just an opinion and in your case it might be masking the value of what you want to impart.
