Can I use this power2max Gravel power meter on a Shimano road drivetrain?

Name: power2max NGeco Praxis Zayante Carbon Gravel Power Meter Crankset
SKU: 108684
Availability: InStock

Great question! This power2max Gravel power meter features a GRX 47 mm chainline. This is wider than the 44 mm chainlines used on Shimano road drivetrains such as 105, Ultegra and DURA-ACE. However, the chainline on this gravel crankset can be converted to the narrower 44 mm road chainline by use of a power2max MTB Adapter Plate. The adapter plate is placed between the power meter and the gravel chainring, which moves the chainring closer to the bike and gives you a Shimano road chainline.

power2max NGeco Praxis Zayante Carbon Gravel Power Meter Crankset

The NGeco is the newest 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 NGeco Praxis Zayante Carbon Gravel Power Meter Crankset comes fully-loaded. The NGeco is accurate to +/- 2.0% in all environmental conditions and is easy to use with features such as auto-zero and accelerometer-based cadence measurement. In addition, the Zayante is a carbon crankset that is lightweight, stiff and looks good too!

Key Product Details

Compatibility:

Power Measurement:

The power2max power meter measures power at the spider and is therefore able to measure power from both legs.

Dual-leg power measurement, carbon fiber crank arms, accurate to +/- 2.0%, 300-400 hours of battery life, CR2450 user-replaceable battery, left/right power balance with system upgrade, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.

Advice From Our Staff:

This is one of our favorite gravel power meters. From a power meter standpoint, the power2max measures power from both legs, is reliable and accurate. In addition, you get a Praxis Zayante Carbon crankset which is stiff, lightweight and performs great. It’s a wonderful combination. Just make sure you have a Praxis M30 bottom bracket on your bike as the Zayante uses a 30 mm/28 mm tapered spindle.

Other Versions to Consider

power2max NGeco Praxis DOON: For riders who are looking for a carbon crankset that is even lighter, we recommend the power2max NGeco Praxis DOON Carbon Gravel Power Meter Crankset. This crankset features the same P2M NGeco power meter, but uses Praxis DOON carbon crank arms which are lighter than the Zayante. This power meter crankset also uses a 30 mm spindle.

Compatibility

Drivetrain:

1x chainrings: Compatible with 11- and 12-speed drivetrains (not compatible with SRAM 12-speed chains).
2x chainrings: Compatible with 9-, 10- and 11-speed drivetrains as well as with 12-speed Shimano, SRAM and KMC chains.

Bottom Bracket: This power meter fits Praxis M30 (30 mm/28 mm) bottom brackets. If you currently have a Praxis M30 MM crankset on your bike, you should be able to re-use your existing bottom bracket. However, if you are changing spindle sizes, you will need to replace your bottom bracket.

*Power Balance Upgrade

The power2max NGeco measures power from both legs right out of the box. However, with power balance, you can see how much power each leg is generating individually. If this information is important to you, you can choose to upgrade the power meter at any time. (Please note, you can also purchase the NG version of the power2max which comes with this feature unlocked, along with a rechargeable battery and a longer 5-year warranty.)

You can upgrade your NGeco using the power2max app once you receive the power meter. The cost to upgrade is 50 euros.
