Sigeyi AXO SL QO GRAVA Gravel Power Meter Crankset

Sigeyi AXO SL QO GRAVA Gravel Power Meter Crankset

The Sigeyi AXO SL QO GRAVA Gravel Power Meter Crankset pairs the popular AXO SL power meter spider with QO GRAVA carbon crank arms. The spider measures power from both legs, delivers accuracy rated at +/- 1.0 percent and weighs just 80 grams. It also includes a rechargeable battery with up to 300 hours of ride time, auto zero calibration and left and right balance data.

The QO GRAVA crank arms use Mitsubishi Pyrofil carbon fiber, a material first developed for aerospace use. This carbon dampens vibration while staying stiff and lightweight for efficient power transfer. KevTex Kevlar fibers reinforce critical areas, increasing impact resistance and making the crankset ready for demanding gravel terrain. A 29 mm DUB spindle provides wide compatibility, and arm lengths from 165 to 172.5 mm make this striking crankset a great fit for a wide range of gravel riders.

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.

Key Features of the Sigeyi AXO SL QO GRAVA Gravel Power Meter Crankset

• Strategic Kevlar Fibers: KevTex at the ends of the crank arms improve durability against rock strikes while riding on loose terrain.
• Vibration Dampening: Not only is this crankset lightweight and great at transferring power to the bike, the use of Mitsubishi Pyrofil carbon fiber helps reduce vibration transmitted to the rider which in turn reduces fatigue.
• Power Measurement: The Sigeyi power meter measures power at the spider and is therefore able to measure power from both legs, accurate to +/- 1.0%.
• Long Battery Life: A rechargeable battery keeps the data flowing for 300 hours of riding.
• Wide Connectivity: Sigeyi uses both ANT+ and Bluetooth Smart for hassle free data collection.
