It should magnetize to the end of your pedal spindle on the back of your crank arm. Line up your cadence sensor to this magnet and voila... no strap. Clean and bump proof. I rode and raced mine all season (and my road bike as well) without bumping the magnet loose or losing it.
Yeah, I've had zip-tied crank cadence magnets fall off or move around a lot.
Now I use 3M Outdoor Double-sided tape to tape the cadence magnets to my road bike and track bike (when not using the SRM). I've never had one fall off and it's also a clean look. I've been using this method on my bikes and the bikes of friends since 2009.
The tape is rubbery, not hard. It peels off with some effort. It's about as strong as old chewing gum might hold (if that makes sense). Once you get it started, it peels right off.
Here's what I use:
I bought one roll for $5 back in 2009 and I'm still using it
- Decide where the magnet should go.
- Wipe the area on your crank arm with alcohol to remove any grease or dirt.
- Cut off about 1 inch of tape.
- Affix the magnet to it.
- Cut off the excess around the magnet.
- Take the red backing off of the other side.
- Stick it and forget it
