The Race Face Era crank arms are made from carbon fiber and have an upgraded pedal insert which is bonded directly to the carbon layup. Additionally, stainless steel wear plates are are integrated into the crank arms to provide protection against heel rub and additional stiffness for power transfer.

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.


Other Versions to Consider

Sigeyi Race Face Next SL Crankset: If you’re looking for a power meter crankset that is a bit lighter and designed for XC and trail riders, consider the Sigeyi Race Face Next SL MTB Power Meter Crankset. This crankset uses the same Sigeyi AXO power meter, but comes with Race Face Next SL carbon crank arms. The Next SL arms are some of the lightest available.


Chainrings: This power meter requires a 104x4 BCD MTB chainring (which is different than the direct mount chainrings found on many Race Face 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.

If you purchase a new chainring with your power meter, we will bolt it on to your power meter before shipping, which will make installation that much easier when you get it.

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.
