Sturdy aluminum road bike crankset with integrated Power2Max® power meter and precise power measurement.

The FSA PowerBox Alloy crankset combines a high-quality FSA aluminum crankset with the proven power measurement technology of Power2Max®. It records the total power output of both legs as well as cadence and reliably transmits training data via ANT+ to compatible bike computers.

The forged duralumin crank arms and integrated 30 mm BB386EVO axle provide high stiffness and efficient power transfer. Thanks to its versatile BB386EVO design, the crankset can be used with numerous road bike frames when paired with suitable bottom brackets and adapters.

With a 50/34-tooth chainring combination, the crankset offers versatile compact gearing for fast road rides, long tours, and challenging climbs. The CNC-machined AL7075 aluminum chainrings are suitable for 10- and 11-speed drivetrains.

Highlights:

• Integrated Power2Max® power meter: Measures the total power of both legs as well as cadence.
• Measurement accuracy of ±2%: Reliable power data for training and competition.
• ANT+ data transmission: Compatible with numerous bike computers and GPS devices.
• Bluetooth Ready: Bluetooth transmission can be enabled via an optional upgrade.
