Universal Cadence Magnet

Easy to put on, works like it supposed to.

Sticky part on back is not sticky, used 2 sided tape to secure it for cable tying.

The included adhesive tape does not work well, but the small size is perfect for a narrow gap between crank and chainstay. Comes with a zip tie, or use a dot of outdoor rated double sided foam tape.

Yes, it’s just a magnet but I’ve had them that weren’t strong enough to trip the switch (or whatever). This one works fine!

Ugly zip strip, and it doesn't stay put. You could add some foam tape to hold the zip-strip in place.If your pedal axle is steel (magnets stick to it), then you can buy a 10-pack of 1/2" by 1/4" magnets to stick on your pedal axle. Much better.If your pedal uses a wrench instead of a hex key, then a 1/2 by 1/8 will also work, and will be slightly more accurate, but you'll never dig it out of the hole until the pedal is removed.If you're stuck with aluminum, brass, or titanium pedal axles, then you may want to put a blob of clear "Shoe Goo" on this before strapping it down, and let that cure for a day. That will keep it in place better.

Clever design

I wish this is what I would have received with the original computer purchase. I went through too many of those rubber ones before installing this. Simple and effective
