This little magnet allows you to stealthily get cadence from your Quarq power-meter. There are two ways to mount the magnets; using the included putty to glue one to your frame; attaching the cable guide mount between the cable guide and your frame on the bottom of the bike's bottom bracket shell and then placing the magnet on the cable guide mount.
