Description

FSA Road PowerBox Carbon Crankset Power Meter

The FSA Road PowerBox Carbon Crankset Power Meter is a crank-based power meter, with single-leg power being measured at the spider. Specifically, it uses Power2Max’s proven spider design. The FSA PowerBox Carbon uses FSA’s 7075 aluminum 110 mm BCD chainrings, FSA hollow carbon arms and a BB386EVO 30 mm spindle. 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). The result is an accurate, extremely versatile power meter that comes with top-notch FSA chainrings and crank arms, and costs of fraction of the price of other, crank-based power meters.

FSA Carbon Crankset Power Meter Options

• Chainring sizes: 53/39 | 52/36 | 50/34
• Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm | 177.5 mm | 180 mm

Upgrade Options

• Left/Right Power Balance: The Left/Right Power Balance upgrade allows you to see your estimated left/right power balance. That is, how much power each leg is generating. Please note, this requires a bicycle computer that is capable of displaying left/right data (most new computers are). The cost of this upgrade is $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 FSA Road PowerBox Carbon Crankset Power Meter uses a BB386EVO 30 mm axle. This makes the power meter compatible with virtually every frame set when used with the correct bottom bracket and spacers.

The chainrings are compatible with Shimano 10- and 11-speed groupsets, SRAM 10- and 11-speed groupsets and Campagnolo 10-speed groupsets. This allows you to use a wide variety of chanrings.
