The crankset measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 448 grams for the 170 mm visions. The power meter also features a rechargeable battery with 300 hours of ride time, auto-zero functionality, and left and right leg power balance. The Sigeyi crankset uses 29 mm spindle and fits DUB bottom brackets.

Advice From Our Staff:

Sigeyi makes some of our best-selling power meters and if you are looking for a full crankset, this is their most affordable option. The Sigeyi crankset is made of high-grade aluminum 7075 so it’s stiff and lightweight. In addition, it takes both 110×4 as well as 110×5 chainrings. Please note it uses a 29 mm DUB spindle so you must use a DUB bottom bracket with it.


Options For This Power Meter

BCD: 110 5-Bolt | 110 4-Bolt

Crank arms: 170 mm | 172.5 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.


Chainrings: The power meter fits 110 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

The 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Shimano 12-speed chainrings.

Bottom Bracket: This power meter fits 29 mm DUB bottom brackets. If you are ordering the same size as you currently have 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.
