Cateye Computer On Mavic Crossride Disc Wheels - Magnets?

EViS

I was going to transfer my Cateye from my old Rockhopper to my new Cube LTD Race. The wheels on the Cube are Mavic Crossride Disc and the round magnet which attaches to the spokes gets attracted to the spokes which must mean they are steel?

Will this interfere with how the computer calculates distance/speed at all?

No, the computer/sensor works on when the magnet goes past, which will still be once per revolution. The fact the magnet is also attracted to the spokes means nothing.

I'm would have thought your old wheel will have had steel spokes too.

EViS

The magnet wasn't attracted to the old spokes, so I would guess they weren't steel?

Also, the new spokes are quite flat so the magnet turns to sit at an angle (some 20 degrees) to the sensor once gripped. Would this cause a problem?

You can get magnets that have a slot for flat spokes I have one on my Crossride front wheel. Got it from Halfords I think but it was a few years back.

I shall try and find one, thanks for the heads up.

No. The spokes on my road bike are the same.

Have you actually fitted it? Does it pick up the movement when it starts spinning?

EViS

I haven't fitted it as I have run out of 2.5mm cable ties and have ordered some.

Ah right. As I said, it should be fine.

Great, will report back once done. If anyone does find a source for flat-spoked magnets, do please let me know .
