Professional Assembly (Optional)
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 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.
