This is a 22mm handlebar extension that fits on 22mm bicycle handlebars to mount accessories.
I needed a handlebar extension to mount the throttle of my 'iMortor' electric wheel on my bicycle. The flimsy aluminum one that was supplied hat a diameter that was too large to be mounted effectively.

2 15mm M3 screw
4 (or 3) M3 nuts
