A FUNDAMENTAL TOOL

The FSA MTB Carbon PowerBox is an ultralight fundamental tool that will help athletes track their data directly during both training sessions and races: in fact, the many advantages provided during a race are much more important than a few grams difference.

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.

ATTRACTIVELY PRICED

The PowerBox Alloy Crankset is very attractively priced and is backed by consistent and reliable performance.

Description

FSA’s MTB PowerBox Alloy Crankset employs a P2M convertible spider design for multiple chainring options. FSA's alloy arms and BB392EVO 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 (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 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.
