No clue about Magicshine stuff.

Paul's Gino uses, like, a mid fork brazeon, it needs a bolt, thru it.
to some thing with a hole in the side of it. like fork tip eyelets,
low rider mounts in the side of the fork etc.

I have a 5mm braze on that was added to my Bruce Gordon Low rider rack
its on the hoop , right side.. I have a 'planet bike' handlebar light on it.
and so also have a bright flashlight when I need one on my touring bike.

there are others that are threaded, with a strong helicoil insert, like V O sells,
it replaces the the adjusting nut on QR skewers, so is on axis with the axle.
both are a handlebar like tube to mount handle bar lights onto.

Can't help you with that specific brand of light,
just a generalization as to the mounts to stick it on.

Yea, the chronometro knob works too, it's a computer mount for aero bars
adapts well for other uses..
