power2max NG Shimano MTB 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 Shimano MTB 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!

 

Key Product Details

Compatibility:

This power2max is compatible with Shimano MTB direct mount cranksets using a 1x chainring. This includes the M9100, MT900-1, M8100, M7100 and M6100. Regarding chainrings, it requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many Shimano MTB cranksets). If you don’t already have a 104 BCD 4-bolt chainring, we offer several to choose from. 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 super solid option for Shimano MTB direct mount cranksets. Sure you have to change your chainring to a 104 BCD version, but this power2max measures power from both legs, is accurate and 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

Chainline and BCD: This power meter is available in the following chainline options:

  • 1X Standard | 104 BCD
  • 1X Boost | 104 BCD

Tip – If you have a 148 mm rear hub, your bike has boost spacing. If you have a 142 mm rear hub, your bike has standard spacing.

Lock Ring Tool: This page also allows you to purchase your power meter with the Shimano Direct Mount Lockring Tool, which is required for installation. We recommend you order it unless you already own one.

 

Other Versions to Consider

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 Shimano MTB Power Meter version.

Compatibility

Crankset: The power2max NG Shimano MTB Power Meter is compatible with Shimano MTB direct mount cranksets using a 1x chainring such as the M9100, MT900-1, M8100, M7100 and M6100.

Chainrings: This power meter requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many Shimano MTB cranksets). If you don't already have a 4-bolt chainring, we offer several different MTB chainrings for Shimano power2max.

If you purchase a new chainring with your power meter, we will bolt it on to your power meter before shipping, which will make installation that much easier when you get it.
