Cadence Magnet - Hidden Spindal Cadence Magnet - (BLACK) Polar, Garmin, Sigma, Cat Eye
Innovative magnet for cadence sensor that can be installed directly on the pedal axle (as long as its magnetic of course) and uses magnetic attraction to stay anchored to the crank. So its not necessary to use clamps, glues and tapes, or ties. Mounts flush - stays in place - and easily removed if neccesary. On some carbon cranks a small washer can be used to "space or shim" the cadence magnet closer to flush on the back side of the crank. Washer included. Yes it works with the gaps pictured and on mountain bikes that are raced and ridden hard in dirt and mud. It stays attached no problem. BLACK MAGNET
