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.

These cranksets have three small bolts that secure the crank arm to the spider and can be seen from by viewing the backside of the crank. Regarding chainrings, this power meter is compatible with 110 BCD 5-bolt and 110 BCD 4-bolt chainrings, depending on the version ordered. See Compatibility tab for more information.

Power Measurement:

The XCADEY power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Dual-leg power measurement, accurate to +/- 1.0%, 150 hours of battery life, rechargeable battery, very lightweight, left/right power balance, active temperature compensation, ANT+ and Bluetooth compatibility.

Advice From Our Staff:

The XCADEY XPOWER-S GEN2 Praxis Road Power Meter is a great way to add power to Praxis direct mount cranksets. It measures power from both legs, is accurate and affordable. In addition, since it bolts on to your existing crankset, there is no need to buy new cranks or change bottom brackets. It is also lightweight which makes it a great option for cyclists looking to minimize added weight.

 

Options For This Power Meter

BCD: This power meter is available in the following BCDs in order to fit your choice of chainring sizes:

  • 110 5-Bolt | 110 4-Bolt

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 hidden bolts chainrings. For the 5-bolt option, you must use a hidden bolt chainring. With a hidden bolt chainring, the chain catch pin is aligned with a chainring bolt (please see image below). Many chainrings have a moveable catch pin, which allows you to move the catch pin into the correct position. If your current chainring is not compatible, we recommend the Praxis Works Buzz Road Chainrings which has a movable catch pin and is compatible with this power meter.

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.
