Stages Cycling FSA Energy 386EVO Power Meter Crank Arm (2nd Gen)

When your time on the bike is limited and you’re looking to increase your performance, the Stages Cycling FSA Energy 386EVO Power Meter Crank Arm is a worthy addition to your ride. Providing an accurate, reliable and immediate display of your data allows you to follow a training plan to the tee, ensuring your goals are within reach and you’re performing how you should.

This power meter attaches to your left side FSA Energy 396EVO crankset, ensuring no drivetrain components are affected. Not only this, but the easy attachment makes it easy for taking it on and off when you need to clean your bike.

Stages Cycling understands that sticking to a training programme means going out and battling against the elements, no matter what they are. For this reason, they’ve included their highly renowned ‘active temperature compensation’, which stops any drop or rise in temperature from affecting the accuracy of the power meter. Thanks to this, Stages boast that the FSA Energy 386EVO Power Meter has a consistent reading of +/- 2%.

It doesn’t matter whether you’re laying down the power on the flats or spinning up a steep gradient, Stages have ensured a reading of 0 - 2500 watts, and 20 - 220 rpm - which further increases its versatility when adopting a new training programme.

The IPX7 water resistance rating further ensures the power meter is protected from the elements, whilst the tool-free battery replacement with a battery with 200+ hours of life stops you running flat when you’re out on the trails.

Is my bike compatible with Stages Power Meters?

To help find your current crank model, check the inside of the crank arm for the model and length.

The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm allen wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
