Spoke Magnet Slippage(7 posts)

Spoke Magnet Slippagepitt83

I got a Polar HRM / computer for christmas. I can't seem to keep the wheel magnet from spiraling outward on the spoke due to centrifugal force. It seems installed per the directions, but is very loose.

I'd like to stop it from spinning out, but don't want to super glue it or anything permanent.

Ideas?

What type of wheels/spokes are you using? Are you using the big round magnet? There is much smaller ligher aftermarket magnets, or ones specific for your wheels that work very well.

It's Polar's small magnet, about 8mm. See how it's spun out away from the sensor?

Spokes are 14ga straights and that's what I'd likely use on any wheel in the future, so if I need to modify the magnet a little to make it work, that would be an OK solution.

i'd give the superglue a shot, you can scratch superglue off metal with a fingernail so i don't think it really counts as a "permanent" alteration.
DUH! I got it now!pitt83

If I slide the magnet below the sensor (toward the hub) and put a drop of glue ONLY on the spoke, the magnet will stop sliding outward at the dried glue. Don't need glue on the magnet meaning I'll be able to put it on another whell w/o damage.

With round spokes, a dot magnet, that is held on with a screw, works best. The Polar magnet is good on bladed spokes.
