0 for 3 cannondale on the crank sensor installation. Way too thick to snap the sensor around.
Swytch to their credit has several alternatives to make it work so it looks like I will be using my wire cutters to carve the sensor up. I am thinking that I probably should have installed this on a single rider first.
If your bike has no clearance on the crankset then this is the correct magnet for your kit (it doesn't help that I'm putting the kit on a different bike from when I ordered)
