Zone DPMX is the world’s first wearable power meter. It’s affordable, portable, and provides dual left and right power measurement. Attached to your shoes, not your bike, so you can move between bikes and measure power on all of them. Compatible with Speedplay® Zero pedal and cleat systems, and works with ANT+® bike computers and smartphones. From best bike to winter bike to trainer to loaner, just change bikes and go – and your power meter goes with you.
