Enabling you to add pedal power and cadence analysis to your bike without having to change your entire chainset, Stages Cycling brings you its highly accurate Power Meter L non-drive-side crank arm. A perfect choice for performance-seeking cyclists, this model is specifically designed for use with Shimano 105 R7000 chainsets, perfectly matching the aesthetics and colour of the original arm. Its advanced strain gauges are accurate to within +/- 1.5% and the arm can connect to compatible bike computers by ANT+ or Bluetooth wireless connection. This means you get instant feedback, so you can train to specific power zones.
