The power2max is a wonderful power meter and we highly recommend it (affordable, accurate, works great), however you must confirm you have a compatible Praxis crankset. If your Praxis crankset uses the direct mount interface, then yes, power2max NGeco Praxis Road Power Meter will work.
Direct mount cranksets (left image) have drive-side crank arms that can be removed from the crankset. They can also be identified by 3 bolts located on the inside of the spider which are used to secure the spider to the crank arm. Most modern Praxis cranksets are direct mount. This includes Zayante M30, Alba M30 and Zayante Carbon M30.
You must ensure your Praxis crankset uses the direct mount interface (indicated by 3 bolts on the inside of the spider) in order for the power2max power meter to fit.
Please also note the smallest inner ring that will fit on this power meter is a 34T. It is not compatible with Praxis 48/32 chain rings.
Other Praxis Power Meter Options
If your Praxis crankset is the standard version (not direct mount), the power2max spider (pictured above) will not work, however you still have two options:
1) You can replace your crankset for a new version with power. We would recommend the power2max NGeco ROTOR ALDHU Road Power Meter Crankset. It’s our best-selling power2max crankset. Please note, most Praxis cranksets use unique tapered bottom brackets so you will likely have to replace your current bottom bracket if you change cranksets.
2) You can use power meter pedals, as they will bolt up to any crankset.
