Cycle computer on Uni.

Today I bought a cateye wireless cycle computer to put on my KH24. I want to see how fast I can get and if my speed is improving on my daily commute.
However I am unsure of the setup - worried that it will come off or bust when I come off. Any words of wisdom?

I’ve had no upd problems with mine, If you haven’t got a handlebar to attach the receiver to I suggest mounting it on the crown although this isn’t easy to see your instantaneous speed.
