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.

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.

as described

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.

It fits into the pedal bolt hole on your crank arm. Out of the way and works.

Para mi bicicleta

This was easy to attach in the right spot to replace the magnet that got lost 10 years ago. It worked right away even though I used it for a different brand of cycle computer that is no longer sold or supported. 5 stars seems exuberant for such a mundane item, but really, it did everything it should, it couldn't be any better.
