Product Description



For decades cyclists have spent time meticulously lining up a speed/cadence sensor with its corresponding magnet. We said enough is enough. Those minutes are better spent crushing Strava segments than crouched in the corner of the garage fidgeting with a tiny magnet.

Simply install the battery, orient the sensor to program it for speed or cadence, and mount it on either the non-drive side crank arm or the bike’s hub, front or rear will do. Our low-profile Magnetless Speed or Cadence sensor harnesses the advances in accelerometer technology to leave the magnet in the dust – along with your competition.
