Now available for download and purchase are the PowerBox Upgrades for the FSA PowerBox giving additional data during the ride and for analyzing your training sessions. Upgrades available are:

Bluetooth upgrade
With this upgrade your FSA PowerBox can transmit data via Bluetooth Low Energy (BLE or Bluetooth Smart) to your bike computer.

Left/Right-Balance upgrade
The L/R balance shows you the percentage each leg is contributing to your total power output. (power left = pressure on the left pedal + pull up on the right pedal; power right = pressure on the right pedal + pull up on the left pedal).

Pedal Smoothness upgrade
Pedal smoothness is an advanced metric for riders who want to optimize their pedaling. It shows you how evenly power is applied throughout the whole 365 degree pedal rotation. FSA PowerBox power meters collect the data for both legs combined. Please note that transmission of this data to your bike computer is only possible via ANT+.

Torque upgrade
Torque is an interesting value especially for sprinters and track riders who want to measure their peak power output. This value shows you the power independent from your cadence. Please note you must check if your bike computer can show the torque value before upgrading your FSA PowerBox.
