Description

 FSA’s ROAD PowerBox Carbon Crankset employs a P2M convertible spider design for multiple chainring options. FSA's hollow carbon arms and BB386EVO spindle mated together produce a very lightweight, extremely versatile power meter crankset available with a double chaining configuration.

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 (included)
With this upgrade 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 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 360 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+.

How? Go to the Support page on our website, log in and buy the upgrades you need following the instructions.
