cadence reading fault?

Not sure where to post this but here's the problem. I lost the magnet (came off on a ride from the crank) and then followed the advice given here of replacing it with a neodinium magnet that's strong enough to stick to the crank. Any way the problem is that the cadence reading is now all over the place, being about double what it was. Any ideas? Anyone had the same? Is the magnet that comes with the unit special in some way? Thanks in advance for any responses.

no, a magnet is just a magnet, although leading physicists still are unable to fully explain the mechanism of magnetic attraction. Neo's are very strong and may be causing too much field deflection when close to the sensor. The original magnet with these devices is pretty weedy. Just find a spot where the sensor can be moved a bit further away from the magnet and everything will be ok.0

Thanks for the reply. will try the magnet in another position.0

Buy this. Cheap and specific for attaching to the spokes.0

OP. I use the neodymium magnet on several bikes. It works fine. I have 12mm ones on the end of the pedal spindle. This does mean repositioning the sensor unit and the wheel magnet. I find the extra strength of the magnet means it can be further away from the sensor (about 10mm in my case) but you must still line it up with the marks correctly.0 -
