IDEAL FOR CLIMBING AND GRAVEL

Whether it’s tackling climbs on gravel, or hitting steep gradients on the road, there are times when using even a compact chainset can leave you wishing you had another gear or two.

LESS WEIGHT

The crank spider has been reworked with a 90mm bolt-circle diameter, so the smaller rings can be direct-mounted, similar to one-by systems. This saves weight and improves the stiffness of the chainset.

VERSATILITY

It is very versatile and allows also the rider to stay in the middle of their cassette for longer, improving chainline and thus efficiency.
Unleash your power with brandnew FSA PowerBox Road

New catchy black graphic, new chainring combination and also available in SuperCompact version. Are you ready to unleash your power with the new FSA Powerbox?

Description

 FSA’s ROAD PowerBox Carbon SuperCompact 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.
