Sigeyi 5DEV MTB Power Meter Crankset

The Sigeyi 5DEV MTB Power Meter Crankset combines the Sigeyi AXO MTB power meter with 5DEV R-SPEC Trail crank arms to make a trail and enduro focused power meter crankset with the latest MTB crankset technology. Designed to take on any trail, the Sigeyi AXO power meter is a lightweight spider-based power meter that pairs well with the durable and stiff 5DEV R-Spec Trail crank arms.

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. Therefore, you can use it with your favorite head unit and training platforms.

5DEV R-SPEC Trail crank arms are machined from space-grade 7050 billet aluminum to provide extra stiffness and durability. Made to be compatible and customizable for many riders, this crankset is available in both DUB and 30 mm spindle diameters with crank lengths as short as 155 mm.

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 are looking for a MTB power meter crankset at a lighter weight, we recommend the Sigeyi Race Face Next SL MTB Power Meter Crankset. This crankset uses a Sigeyi AXO power meter with Race Face Next SL carbon cranks. This makes for an extremely light power meter crankset.

Compatibility

Chainrings: This power meter requires a 104x4 BCD MTB chainring. 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 is compatible with DUB and 30 MM bottom brackets, depending on the spindle selected. If you currently have a DUB or 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.

Spacing: This crankset is only available with a Boost spindle. Please make sure your mountain bike uses the same spacing for this power meter crankset to be compatible.
