SRAM RED E1 1x AXS Aero Power Meter Crankset
The SRAM RED E1 1x AXS Aero Power Meter Crankset is the perfect 1x power meter for triathletes, time trials and cyclocross racers! The 1x direct mount aero chainring provides a gear range that is perfect for racing and flatter terrains. In addition, Quarq’s premier DZero power measurement technology is +/- 1.5% accurate and has active temperature compensation. This power meter also features dual ANT+ and Bluetooth SMART, left and right power balance and a full 2-year warranty.
This power meter crankset uses SRAM’s latest carbon crank arms. Thanks to a new and optimized carbon layup, these are SRAM’s lightest road cranks ever. The continued use of a DUB spindle means they are compatible with a wide range of frames and bottom brackets. Additionally, SRAM has added new crank lengths, including as short as 160 mm.
Key Product Details
Compatibility:

Power Measurement:

Key Features:
Dual-leg power measurement, integrated 1-piece chainrings, lightweight carbon crank arms, accurate to +/- 1.5%, CR2032 user-replaceable battery, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.
Advice From Our Staff:
This is SRAM’s top-tier aero 1x power meter crankset. It uses carbon crank arms and makes your drivetrain simpler and lighter by removing the need for a front derailleur. Because it uses a spider-based power meter it measures power from both legs and provides left vs. right power balance. While the RED chainrings are made to last 50% longer than SRAM’s 11-speed chainrings, the chainrings cannot be replaced when worn, since the rings and power meter are one piece. Most customers can get many years of life out of the power meter before it needs to be replaced and SRAM offers a 50% off replacement when needed.
Options For This Power Meter
- Chainrings: 48T | 50T | 52T | 54T | 56T
- Crank arm lengths: 160 mm | 165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm
