Sigeyi AXO SRAM RED E1 Power Meter Crankset

Sigeyi AXO SRAM RED E1 Power Meter Crankset

The Sigeyi AXO SRAM RED E1 Power Meter Crankset combines the Sigeyi AXO spider with ultra-light SRAM RED E1 carbon crank arms. This Sigeyi power meter spider measures power from both legs, is accurate to +/- 1.0% and weighs only 105 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 RED E1 carbon crank arms, which is the lightest and stiffest offering from SRAM yet. These crank arms shave 29 grams off the previous version while using a DUB spindle to maximize compatibility. 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.
