The Stages 105 R7000 Power L crank arm enables left-side power measurement. Like all Stages power meters, it features Active Temperature Compensation (ATC) technology, which ensures consistent measurement. Measuring accuracy is +1.5/-1.5 %, and measuring sensors add only 15 g in overall weight.
When you combine Stages Power L with the Stages LINK training platform and a Stages Dash cycling computer, it provides you with additional data to achieve maximum performance, just like the pros do. The Stages Power L power meter is not only compatible with the Stages Dash, but also with any third-party bike computer as long as it can display performance data and works with ANT+ or Bluetooth.
Stages power meters have accompanied athletes in Tour-de-France victories as well as many national and international titles. If you see racing as the ultimate test for the best products, the Stages Power L has more than proven itself as a power meter.
