Sigeyi Praxis G2 LYFT MTB Power Meter Crankset

The Sigeyi Praxis G2 LYFT MTB Power Meter Crankset combines the Sigeyi AXO MTB power meter with Praxis G2 LYFT carbon crank arms. The result is an accurate and lightweight power meter crankset for XC and trail riders.

The Sigeyi AXO power meter features dual leg power measurement, +/- 1.0% power accuracy and 300 hours of battery life. This power meter also has auto-zero functionality and connects with ANT+ or Bluetooth SMART, allowing you to use your favorite head unit and training platforms.

The Praxis G2 LYFT crank arms are made from carbon and use a 30 mm spindle. They use an aluminum preload adjuster to make set up and installation easy. These are Praxis’ flagship MTB cranks and are made to be both lightweight and durable.

Dual-leg power measurement, carbon crank arm construction, accurate to +/- 1.0%, 300 hours of battery life, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero functionality (automatic calibration). See Specs tab for more information.

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: This power meter requires a 104x4 BCD MTB chainring (which is different than the direct mount chainrings found on many Praxis MTB cranksets). If you don't already have a 4-bolt chainring, we offer several to choose from.

The smallest chainring you can use on a Sigeyi MTB power meter is a 30T round or 32T oval.

Bottom Bracket: This power meter fits 30 mm bottom brackets. If you currently have a 30 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.
