If you have a bike computer with cadence sensor let me know if you would be interested in buying a cadence magnet. See the attached image. All metal quality and fits into your pedal's hex slot. $6 dollars each. This is zip-tie less. You decided if you like it and if you want one email me for more information. The image for show purpose have magnet sticking out. The magnet is actually flush with the hex slot. Low profile and looks great. Other magnets are held together like a band-aid strap to your crank arm and isn't as appealing. No plastic parts mean it is going to be with you for a long time. Product brought to you buy CyclingSimplified.
