The Stages Dash performance training GPS head unit is specifically designed to coach a rider to his or her best performance. In the five years since launching the Stages Power meter, Stages Cycling has optimized its use with 3rd party cycling computers, but discovered a need for a highly-focused, customizable, training device. Stages Dash answers this unmet need with the delivery of robust Bluetooth and ANT+ connectivity to Stages Power and 3rd party devices, plus GPS capabilities, while introducing new features including the ability to offer guided workout coaching and specific provisions to manage critical training metrics across all devices.

The redesigned, reimagined Stages Dash M200. Built for Performance. Featuring a brilliant 2.2” full-color screen, cycling specific maps, and a full assortment of training features. Automatic profiles make Dash the easiest computer to use with every bike, and the Stages Cycling app makes it the easiest computer to customize. No matter where or how you ride, Dash allows you to simply hop on and go.
