FSA Power Box SC Road Alloy crankset - 50/34

The FSA PowerBox ROAD carbon crankset uses a convertible Power2Max spider for different chainring options. The hollow carbon arms and the BB386EVO spindle make for an extremely lightweight and versatile crankset with a power meter, available with a double chainring configuration. Updates that provide additional data during rides and allow for the analysis of training sessions are now available for download and purchase.
The available updates are:
Bluetooth (included)
With this update, your FSA Powerbox can transmit data via Bluetooth Low Energy (BLE or Bluetooth Smart) to your bike computer.
Left/Right Balance (included)
The L/R balance displays the percentage with which each leg contributes to the total power output. (left power = pressure on the left pedal + recovery on the right pedal; right power = pressure on the right pedal + recovery on the left pedal).
Pedal Smoothness (via update)
Pedal smoothness is an advanced metric for athletes who want to optimize their pedaling. It shows how evenly the pedal stroke is distributed. The powerbox power meter collects combined data from both legs. Transmission to your bike computer is only possible via ANT+.
Torque (via update)
Torque is a very interesting value for all sprinters or track athletes. This value displays power regardless of your cadence. Warning: ask your bike computer manufacturer if the torque efficiency value is supported before updating your Powerbox.
