Advice From Our Staff:
This is one of our favorite road power meters. From a power meter standpoint, the power2max is a wonderful power meter. It measures power from both legs, is super reliable, accurate and is reasonably priced. You also get the Praxis Zayante Carbon crankset which is stiff, lightweight and performs beautifully. It is really a great 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.

Professional Assembly (Optional)
We are happy to professionally assemble your power meter crankset if you select this option when ordering. This ensures your crankset is correctly built and saves you time. Professional assembly includes:
- Mount the power meter to the cranks and tighten to factory specifications
- Apply multi-purpose bicycle grease where necessary
- Install chainrings on the power meter (if chainrings are ordered)
Please note – while we tighten everything to factory specs, it is still your responsibility to routinely check your power meter crankset to make sure all bolts and nuts remain securely fastened.
