The Odi bar ends are great if you are having trouble keeping your plastic or rubber bar ends inside the bar or if you are tired of wearing the regular ones out too fast.
These bar ends are made with a triple-core design which holds the plugs in place. Simply tighten the allen bolt and you are done. And since this system is to some extent size-adjustable, makes these ODI barends compatible with most bars - Both Steel and Aluminium.
Odi has chosen 6061 aluminium for its mechanical strength and resistance to wear.
