The first step is to determine what interface your Praxis crankset uses. Praxis makes both direct mount and standard cranksets (please see the images below).
Direct mount cranksets (left image) have drive-side crank arms that can be removed from the crankset. 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.
IMPORTANT – If you have a direct mount crankset, any of the power meter options below will work. However, if you have a Standard crankset, only the pedal option (at bottom) will fit your crankset.
Crankset Power Meter (Spider Based)
Our go-to power meter for Praxis direct mount cranksets is the power2max Praxis Road Power Meter. It’s accurate, durable, measures the power from both legs and is reasonably priced.
The power2max Praxis Road Power Meter is compatible with the new Praxis direct mount cranksets: Zayante M30, Alba M30 and Zayante Carbon M30. These cranks can be identified by 3 bolts located on the inside of the spider which are used to secure the spider to the crank arm. Please see the image below. Unfortunately, if your Praxis crankset does not use this interface, the power2max will not work.
Also, please 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.
Pros: Moderately priced, VERY reliable, don’t have to change crankset, measures both legs
Power Meter Pedals
Power meter pedals can be installed on your crankset regardless of what version you have. Power meter pedals are very popular for several reasons: they are reliable, accurate, easy to install and can be moved between bikes. We have several versions to choose from, including both single- and dual-sided versions.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
