Sigeyi AXO SL SRAM Force E1 Power Meter Crankset

Sigeyi AXO SL SRAM Force E1 Power Meter Crankset

The Sigeyi AXO SL SRAM Force E1 Power Meter Crankset combines our best-selling Sigeyi AXO SL spider with SRAM Force E1 carbon crank arms. This Sigeyi power meter spider measures power from both legs, is accurate to +/- 1.0% and weighs only 80 grams. 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 SRAM Force E1 carbon crank arms, the latest evolution of the Force crankset from SRAM. SRAM reduced the weight by 60 grams compared to the previous version while retaining the same DUB spindle. In addition, this crankset is offered in two versions: one for road bikes (standard spindle) and one for gravel bikes (XPLR spindle). The Gravel/XPLR version has a wider Q-factor than the standard spindle. This allows for wider tire clearance and is optimized for 1x drivetrains. Both are available in lengths as short as 160 mm all the way to 175 mm so there is an option for every rider.

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.
