power2max NG Praxis Road Power Meter
The NG is the premier model in the power2max line-up. With features such as dual leg power measurement, ANT+/Bluetooth SMART compatibility and left/right power balance, the power2max NG Praxis Road Power Meter comes fully-loaded. In addition, the NG is accurate to +/- 1.0% and is easy to use with features such as auto-zero and accelerometer-based cadence measurement. The power2max NG model also features a rechargeable battery with 150 hours of run time as well as a full 5-year warranty!
NG vs. NGeco
You are viewing the power2max NG. This is power2max’s premium version. It features several upgrades over the NGeco:
- Better accuracy (+/- 1.0% vs. +/- 2.0%)
- Rechargeable battery (vs. coin cell battery)
- Longer 5-year warranty (vs. 2 year warranty)
- Additional training metrics including left/right power balance
Key Product Details
Compatibility:
The power2max NGeco Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets 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. Regarding chainrings, it fits 110 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. See Compatibility tab for more information.
Power Measurement:
The power2max power meter measures power at the spider and is therefore able to measure power from both legs. This NG version is also able to measure your left vs. right leg power balance.
Key Features:
Dual-leg power measurement, accurate to +/- 1.0%, 150 hours of battery life, rechargeable battery, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration), 5-year warranty. See Specs tab for more information.
Advice From Our Staff:
This is a great way to add power to a Praxis 3-bolt crankset. It measures power from both legs, is accurate and very reliable. We believe the price also represents a good value for what you get (even for this more expensive NG version). We highly recommend power2max power meters and use them on many of our own bikes.
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
Other Versions to Consider
Praxis NGeco Version: While the NG version you are viewing here features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics, we also sell the more affordable power2max NGeco Praxis Road Power Meter version.
Compatibility
Crankset: The power2max NG 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 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.
Important chainring notes:
1) Some Praxis cranksets come equipped with direct mount chainrings, while others come with LevaTime 160/104 BCD chainrings. In either case, you will need to purchase new chainrings as these won't work with a power2max power meter. We have several chainrings to choose from on our Chainrings page. If you are not sure if your current chainrings will fit, please contact us so we can help.
2) This power meter is not compatible with Praxis 48/32 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 110. 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.
