Came up this idea yesterday.
Drill out the speedo cap nut so the wire can pass though, needed to use a bit of pastic pipe as a spacer
looks like this when to together
and fitted
just need to mount the magnet on the hub but its dinner time now so will post pictures later when its done.

Not yet thats down to JackpotPeteSR wrote:excellent idea, had chance to test it yet?
im running a mountain bike one from my rear wheel,i take it you have to program in the diameter of the magnets..i would imagine it may be difficult to calibrate your diam being such a small diameter,and any error would be greatly magnified...but im sure its possible...fab idea tho and looks very neat..hope it works
the diameter would be the rolling road diameter of the tyre not the speedo drive were the magnet is mounted a bit like the way final drive is worked out on a gear boxcamel wrote:im running a mountain bike one from my rear wheel,i take it you have to program in the diameter of the magnets..i would imagine it may be difficult to calibrate your diam being such a small diameter,and any error would be greatly magnified...but im sure its possible...fab idea tho and looks very neat..hope it works
We sleep soundly in our beds because rough men stand ready in the night to visit violence on those who would do us harm
very true....my mistake
Great idea Jason, are you able to advise about mounting of the display in the head set, how you do it? What's the visibility of the display like in sunlight, and darkness?

I just did the same on a px disc hub this weekend, great minds etc . Great thing is it removes the problem of the magnet moving with suspension compression. Tapped the speedo drive holding plate (bloody imperial 7/16 thread though) and drilled the worm drive for the magnet too. Works with me spinning it so far - 7mph!
