Upgrade Kit Rally™ RK100 | GARMIN

Transform your Rally RK100 into a dual-sensing power meter
and accurately analyze all your power data.

Paired with the Rally RK100, the Upgrade Kit allows you to obtain a second pedal with a sensor, just like on the 200 versions. This way, you'll have access to left/right leg power balance and Cycling Dynamics (pedaling analysis). You can also modify the pedal body to Rally XC to measure your power on mountain bikes, gravel bikes, cyclocross bikes, etc.

The revolutionary pedaling analysis offered by Cycling Dynamics shows you where and how you generate power when pedaling. It also displays the left/right leg balance and the time spent seated or standing, to study the influence of position on your efficiency. You can also see where you're applying pressure on the pedal and ensure your cleats are correctly positioned.
