Sigeyi AXO Praxis Zayante Carbon Road Power Meter Crankset

The Sigeyi AXO Praxis Zayante Carbon Road Power Meter Crankset combines the Sigeyi spider with the top-of-the-line Praxis Carbon Zayante crankset. This Sigeyi power meter measures power from both legs, is accurate to +/- 1.0% and is lightweight. The power meter also features a rechargeable battery with 300 hours of ride time, auto-zero functionality, and left and right leg power balance. In addition, this power meter uses Zayante Carbon crank arms. This is the company’s Pro-level road crank with light, stiff beautifully crafted carbon crank arms.

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

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)Sigeyi Build Checklist

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.

Compatibility

Chainrings: The powermeter fits 110 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

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.

Common Questions and Answers

Question: I see you sell several different Sigeyi power meter cranksets. What are the differences?

Question: How do I determine what length my current cranks are so I can make sure I get the same size?

  • Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
