magnets for cadence
go to local hardware store get some strong rare earth magnets (didimium work well)
attach a couple or three to your crank/pedal post on the inside of the hole. magnets will attach to the post metal.
this will be strong enough to trip the cadence sensor without having to zip tie them to the crank arm. I was always kicking my magnet out of position on the crank arm and this strong magnet in post hole works like a charm.
I think I'll try that. I just added a cadence/speed sensor on my mountain bike for a Garman Forerunner 305 hrm. I don't like the magnet mounting. Your approach allows moving the magnet further from the bottom bracket which means a better wheel magnet position (for this particular sensor) as well as possibly getting by with a larger than specified gap for the cadence sensor.
I always use a little Shoe-Goo for added bonding around the edge of the magnet and the semsors. They won't come off until you want them too.
