Advice From Our Staff:

This is another one of our favorite road cranksets. The Magene measures power from both legs, is reliable, accurate and very affordable. You also get the Praxis Zayante Carbon crankset which is stiff, lightweight and performs beautifully. Just make sure you have a Praxis M30 bottom bracket on your bike as the Zayante uses a 30 mm/28 mm tapered spindle.

Crank arms: The Praxis Carbon Zayante crank arms come in the following sizes:

  • 155 mm | 160 mm | 165 mm | 170 mm | 172.5 mm | 175 mm


Professional Assembly (Optional)Magene 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.


Other Versions to Consider

Magene Praxis DOON Crankset: If you are looking for an even lighter Praxis carbon crankset, we also offer the Magene Praxis DOON Carbon Road Power Meter Crankset. This crankset features the same Magene power meter, but uses DOON carbon cranks and a 30 mm spindle.


Chainrings: This power meter fits 110 BCD 5-bolt or 110 BCD 4-bolt chainrings. 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: How to I determine what spindle diameter and bottom bracket I am currently using?
