Speed/Cadence Sensor Magnets

Recommended Posts

I use a Polar bike computer, happy with that.

 

Question is, and it may sound a bit of a stoopid one, but does it really matter which magnet is used on the wheel/pedal. The Polar ones are the most ineffective design and get dislodged pretty easily. I see Cateye sells a far more robust looking one. I contacted the Polar guys and they said it must be Polar but I think they're trying to keep me buying their cr~p.

 

I don't see it making a difference, any ideas?

I use a Cateye one and it works fine.

Your LBS should let you check it out in the parking lot/street outside.

For the magnet on my crankarm I used a magnet from a hardware store and stuck it on using clear epoxy. Does the job. Don't see why you couldn't do the same with the wheel one? Maybe also use a really small cable tie as well.

I don't find the Garmin one that great.

 

Went to local magnet specialist and bought small disc shaped "rare earth magnet" . Apparently that rare earth part is quite important as it makes them much stronger, so much so they come with warnings to keep away from credit cards.

 

The nice thing about the disc is it sits perfectly on the reverse side of the small recess of the pedal shaft, and the magnet is more than strong enough to hold it there. In fact, you have a helluva a job to prise it out!

 

I can't claim credit for this idea - it came up when I did a Google search on better cadence magnets.

I've seen a "generic" magnet at Cycle Lab, so I doubt it makes a difference. Magnets are magnets, after all.

I have been using a PRO wheel magnet on my old Polar as well as my current Garmin. I use a stack of 12mm rare earth discs that I bought from Deal Extreme. I stick them to my pedal shaft at the back of the brank. If the fall off, I replace them. They are cheap enough but haven't lost any to date.

 

Polar are taking the p1ss

I've used Cateye for the wheel and works fine.

R50 at Sportmans Warehouse, which is probably a bit if a rip, but I know they do stock them.

Hi All,

 

I also needed some magnets for Polar speed and ordered mine from IHF Products up north. I live in Hermanus in the Western Cape and they said the price includes postage and i received the magnets within two days!

 

I repeat, two magnets plus postage for R60.00? Wow, what good service. now i know why i wear a Polar!

I lost the cadence magnet in an ungraceful dismount. I pulled a magnet off the back of a fridge magnet and cable tied that to my crank. Works 100%.

A magnet is a magnet, the reed switch in your pickup does not care about the brand. As long as the distance between the magnet and the pickup is correct and the magnet is on the correct place as specified, any magnet will work.

Hi, just lost my garmin magnet, where did you get the magnet from - will be doing the same as you as my googling turned up the same result. Thanks

I forget exactly where / the name - it was a place at the next business park along the same road as the interchange park where Builders Warehouse is.I think I google'd rare earth magnets, and then limited the search to just SA
