Performance cyclists and coaches consider power training the best tool around. Power is where the rubber hits the road, the bottom line, the one metric that stays true through varying road surfaces, inclines, temperatures, winds, and heart rates. The Stages Meter gives you access to this race-winning data via an affordable, self-contained unit you can install in minutes. Bilingual ANT+/Bluetooth Smart communication lets you pair it with your favourite device and software.
