FSA's PowerBox Alloy MTB crankset utilizes the P2M convertible spider design for multiple chainring options. FSA's alloy arms and BB392EVO bottom bracket combine to create a very lightweight, extremely versatile power meter crankset that is also available in a double chainring configuration.
The innovations are:
- Bluetooth (included)
With this update, your FSA PowerBox can transmit data via Bluetooth Low Energy (BLE or Bluetooth Smart) to your cycling computer.
- Left/right balance (innovation)
Left/Right Balance shows the percentage by which each leg contributes to your overall power output. (Left power = left pedal pressure + right pedal pull; Right power = right pedal pressure + left pedal pull).
- Pedal smoothness (upgrade)
Pedal Smoothness is an advanced metric for riders looking to optimize their pedaling. It shows you how evenly power is applied throughout the entire 360-degree pedal rotation. FSA PowerBox power meters collect data for both legs combined. Please note that this data can only be transferred to your bike computer via ANT+.
