CATEYE Universal Cadence Magnet – Cycling Computer Spare RPM Cadence Magnet for Road, MTB, Gravel Bikes, Easy Install, Fits All Crank Arms, for ISC-12 Bluetooth Speed & Cadence Sensor

Works as intended, be sure to clean crank arm before attaching.

as described

I got the magnet and installed it on my crank arm. All went well. Of course now that I installed new batteries in the computer and sensor, I wish I could figure out how to get it to display my speed, cadence, heart rate etc. The computer instructions really leave something to be desired. Numerous You Tube videos explain how to reset the computers but the subjects don't seem to have any more idea than I do. Hey but this is about the magnet and it is great.

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.

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

Para mi bicicleta

Worked as intended with a cat eye v2.

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.
