About the FSA MTB PowerBox Carbon Crankset Power Meter

The FSA MTB PowerBox Carbon Crankset Power Meter is a crank-based power meter, with power being measured at the spider. Specifically, it uses Power2Max’s proven spider design. The FSA PowerBox Carbon uses FSA’s 7075 aluminum chainrings, FSA hollow carbon composite arms with a UD finish and a BB392EVO 30 mm spindle. In addition, the chainring features a thick-thin tooth design for maximum chain engagement.

The power meter uses a CR2450 battery (which is very easy to replace), gets approximately 400 hours of battery life and is accurate to within 2% (industry standard).

 

FSA MTB PowerBox Carbon Crankset Power Meter Options

  • Chainring sizes: 38 | 36 | 34 | 36/24
  • Crank arm lengths: 170 mm | 175 mm

 

Upgrade Options

  • Left/Right Power: The FSA PowerBox ships as a left-side power meter. This means it measures the power from your left leg and doubles it to compute total power. At any time, you can upgrade your PowerBox to a dual left/right unit for $50
  • Bluetooth SMART: The PowerBox comes with ANT+ capability. At any time, you can upgrade it to a dual ANT+|Bluetooth SMART unit. The cost of this upgrade is also $50

 

Compatibility

The power meter uses a BB392EVO 30 mm axle. This makes the power meter compatible with virtually every frame on the market when used with the correct bottom bracket and spacers.

The chainrings have a 96|68 BCD and are compatible with Shimano 10- and 11-speed groupsets and SRAM 10- and 11-speed groupsets. This allows you to use a wide variety of chanrings.
