Sigeyi Power Meter Crankset Comparison

Sigeyi power meters are an accurate, reliable and affordable way to add dual-sided power to your road, gravel or mountain bike. Some customers prefer to buy the power meter only and bolt it up to their current crankset, however we also offer complete cranksets (power meter plus crank arms). Specifically, we offer the Sigeyi power meter with crank arms from Sigeyi, ROTOR and Praxis. While the power meter spider on each crankset has the same accuracy and features, the crank arms are different and will provide varying levels of price, performance, compatibility and crank arm length.

Sigeyi AXO

The Sigeyi AXO Power Meter Crankset is the most affordable option. The crank arms are made of 7075 aluminum so they are strong and lightweight. Please note this crankset uses a DUB spindle and is only offered in 170 and 172.5 mm sizes currently.



The Sigeyi ROTOR ALDHU Power Meter Crankset is the most versatile. It also uses an aluminum crank arm however it uses slightly more common 24 mm and 30 mm spindles. In addition, it comes in several different crank arm lengths. The Sigeyi ROTOR ALDHU Carbon Power Meter Crankset is the most expensive. This is because it uses high-end carbon crank arms that are very light and stiff.



The Sigeyi Praxis Zayante Carbon Power Meter Crankset offers a carbon crank arm but uses a spindle diameter that is only used by Praxis (M30). This forces most riders to swap bottom brackets.

While most Praxis spindles use a M30 spindle, the Sigeyi AXO Praxis DOON Carbon Road Power Meter Crankset uses a 30 mm spindle. This makes it compatible with a wider range of bottom brackets. The DOON crank arms are also 66 grams lighter than the Zayante crank arms.


Again, it is important to note that each of these cranksets uses the Siegyi AXO power meter. This is a spider-based power meter that measures both left and right leg power and features +/- 1.0% power accuracy.
