Sigeyi AXO SL CYBREI Carbon Road Power Meter Crankset

The Sigeyi AXO SL CYBREI Carbon Road Power Meter Crankset combines the Sigeyi AXO SL spider with the lightweight CYBREI GP-3 carbon crankset. This Sigeyi power meter crankset measures power from both legs, is accurate to +/- 1.0% and is very lightweight. The power meter also features a rechargeable battery with 300 hours of ride time, auto-zero functionality, and left and right leg power balance.

This power meter crankset features CYBREI GP-3 carbon crank arms. CYBREI spent three years designing these crank arms and made them to be both extremely lightweight and stiff. Tested by UCI and World Tour riders from around the world, these crank arms were made to perform at the highest levels. The CYBREI GP-3 crank arms come in both DUB and 24 mm titanium spindle options. and weigh only 320 grams (DUB 170 mm), including the spindle. Additionally, they are available in a wide range of crank lengths including as short as 150 mm.

Sigeyi AXO SL vs AXO Differences

This new AXO SL is the latest power meter from Sigeyi.

• New Pedal Smoothness Feature: The SL can provide pedal smoothness metrics, helping riders even out their pedal stroke.
• Reduced Weight: This new version is incredibly lightweight, dropping the mass of the power meter spider from 105 grams to 80 grams.
• Improved Stiffness: Despite the reduced weight, the AXO SL is 8% stiffer laterally and 10% stiffer torsionally. This means power transfer to the bike is improved.
• Reduced Volume: Engineers reduced the spider’s total volume by 35% and added a larger rear opening to improve T47 bottom bracket compatibility. In addition the front surface is now flat, allowing for use of covers to complete an OEM look.

The features that made the AXO such a great power meter spider have been kept, such as +/- 1.0% accuracy, auto-zero calibration, active temperature compensation and more.

Power Measurement

The Sigeyi power meter measures power at the spider and is therefore able to measure power from both legs.

Compatibility

This power meter fits DUB or 24 mm bottom brackets and 110 BCD 4-bolt chainrings. This includes all Shimano 4-bolt road chainrings, including Shimano 12-speed chainrings. See the Compatibility tab for more information.

Considerations

Like all spider-based power meters with this functionality, the AXO SL provides estimated power balance data. While this estimation stays highly accurate, it doesn’t provide true left-right power balance like dual-sided power meter pedals record.
