XCADEY XPOWER-S GEN2 Praxis Road Power Meter
The XCADEY XPOWER-S GEN2 Praxis 3-Bolt Road Power Meter is a spider-based power meter that is compatible with Praxis 3-bolt road cranksets. The XCADEY power meter measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 110 grams. In addition, it easily bolts up to your existing Praxis crankset. Therefore, there is no need to buy new cranks or replace your bottom bracket.
The power meter also features a rechargeable battery with 150 hours of ride time, left and right leg power balance, active temperature compensation and a 2-year manufacturer’s warranty. Of course, you also get Bluetooth SMART. This allows you to use the power meter with your favorite indoor training program or app.

Compatibility
Crankset: The XCADEY Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets (left image) have drive-side crank arms that can be removed from the crankset. In addition, if you were to view the backside of the crank, you would see three small bolts or screws that secure the crank arm to the spider or chainring.
Standard cranksets (right image) have a one-piece drive-side crank arm and spider. That is, the crank arm and spider are one solid piece of aluminum.
Most modern Praxis cranksets are direct mount. This includes Zayante M30, Alba M30 and Zayante Carbon M30. It's very important you confirm you have a direct mount version where the drive-side crank arm can be removed. If you are not sure, please send us some images of your crankset and we would be happy to confirm for you.
Chainrings: This power meter is compatible with 110 BCD 4-bolt and 110 BCD 5-bolt chainrings.
What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.
