Description

The FSA Powerbox Carbon Power meter comes from a cooperation between FSA and Power2max. When two big names in the cycling industry come together to work on a project like this, you can expect a high quality end result. This power meter offers single-sided measurement but with the option to expand to dual-sided measurements later on. Due to pending patents, it won’t be until August 2017 that we’ll see an update to go double-sided. Power is measured in the spider of the crankset. The spider is the connection between the chainrings and right half of the cranks.

The FSA Powerbox only needs to calibrated once after being paired to your cycling computer. For now it uses ANT+ only, but after the August update it’ll offer Bluetooth Smart as well. Battery life is between 300 and 400 hours, and replacing the battery can easily be done at home. The Powerbox itself isn’t affected by weather conditions or temperature fluctuations, and offers a measurement accuracy of ±2%. The overall weight of the crankset is impressive on the low side of things at just 585 grams.

Detailed product description

Simple2use
You get on, and it just works. This is how simple and reliable a power meter should be. We’ve done everything in our power to make that happen:

Auto Zero
Every time you stop pedaling for 3 seconds or longer, your Power2Max will reset itself. This way, you’ll always get reliable data and you’ll never have to manually recalibrate your powermeter again.

No Cadence Magnet
You don’t need to fit a separate cadence magnet. Your Power2Max precisely measures your current cadence using the internal accelerometer.

Swapping Batteries
When the time comes to replace your batteries -after 300 to 400 hours (6000-12000 km)- then you’re perfectly able to do so at home. You don’t have to send in the cranks, so you’re not only saving time but money as well.

Built2resist
Power2Max power meters offer exact and reliable data under all conditions: warm or cold, dry or wet, you can rely on the quality of your Power2Max. Our power meters are waterproof and capable of withstanding even the most torrential downpours. The built-in temperature compensation mechanism ensures your Power2Max stays accurate even in changing conditions.

±2% Accuracy
Power2Max power meters offer you state of the art data: our power meters have an accuracy of ±2% or better under all possible external conditions. This has been achieved through a highly refined design and a top-notch production process.

Designed, developed, and built in Germany
FSA produces all of their power meters in Germany. How does that help you? Continuous high quality and a reliable end-product.

ANT+
Power2Max power meters use ANT+ to wirelessly transmit your data to your head unit. The ANT+ protocol ensures a reliable data transfer and is compatible with a wide range of cycling computers.

Left-Right balance
Your Power2Max power meter estimates the contribution of your left and right leg as you ride, providing you with additional useful feedback during your training sessions.

Please note!
Power right = downward pressure on the right and upward force on the left.
Power left = downward pressure on the left and upward force on the right.
