FSA Powerbox carbon crankset 386EVO

FSA Powerbox Carbon

Complete Range of Combinations

Along with the continuing standard 53/39, 52/36 and 50/34 options, PowerBox cranks are now available in a Supercompact version as well as larger chainrings sizes for triathlon: 55T, 54T and 42T.

Precision
A +/-2% accuracy precision is the key quality you want in a power meter. Nowadays, powermeter cranks represent a fundamental tool that will help riders track their data directly during training sessions and to be increasingly more competitive on race day.

Included Upgrades
Bluetooth connectivity and Left & Right leg output analysis are already included without additional cost.



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+.
