The cadence magnet for the GSC10 sensor that attaches to the crank on my bike has disappeared. It's the one that comes in a little oblong black plastic holder with a slot for the zip tie. I guess the zip tie wasn't snugged down enough and trying to clip in from a stop light I think I knocked it off.
Anyway - does anyone know if you "must" use that specific magnet or can I use any old magnet in its place?
I can get a 10 pack of 3/8th's sized rare earth magnets off amazon
http://www.amazon.com/Rare-Earth-Mag...0993339&sr=8-3 for less than what they want for a single set of replacement magnets from garmin http://www.amazon.com/Garmin-Replace...0993400&sr=8-2
PS - Last thought - since a full GSC10 kit runs about $35 am I better off getting that to have a spare? Seems excessive - particularly since I don't ride in the rain unless I get caught out.
