SRAM RED E1 AXS Power Meter Crankset

The SRAM RED E1 AXS Power Meter Crankset is Quarq’s flagship road power meter crankset. Using DZero power measurement technology, this SRAM power meter provides accurate and consistent power readings. In addition, with active temperature compensation, changes in temperature won’t affect your power numbers. It also uses integrated chainrings to save weight and improve shifting performance. The power meter features dual ANT+ and Bluetooth SMART, left and right power balance and comes with a full 2-year warranty.

The RED E1 AXS power meter crankset features 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


This power meter crankset is compatible with SRAM DUB bottom brackets. See Compatibility tab for more information.

Power Measurement:

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

Key Features:

Dual-leg power measurement, integrated 2x 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 premier 2x road power meter crankset. It is 29 grams lighter than the previous generation and is available in more crank lengths. We also like that the power meter 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, please note that 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: 46/33 | 48/35 | 50/37 | 52/39 | 54/41 | 56/43
  • Crank arm lengths: 160 mm | 165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm


Other Versions to Consider

SRAM RED E1 Power Meter Spider: If you already have SRAM RED AXS crank arms and are looking for only the power meter spider and chainrings, we offer the SRAM RED E1 AXS Power Meter Spider.

SRAM RED E1 1x Power Meter Crankset: We also sell the SRAM RED E1 1x AXS Aero Power Meter Crankset. This power meter crankset features the same carbon crank arms, but uses a 1x aero chainring.

Force Power Meter Crankset: This power meter also comes in a Force version. The SRAM Force AXS Power Meter Crankset is not quite as light and stiff as the RED version, however it is more affordable.


This power meter crankset is compatible with SRAM DUB bottom brackets.

Common Questions and Answers

Question: How do I determine what length my current cranks are so I can make sure I get the same size?

  • Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.

1 review for SRAM RED E1 AXS Power Meter Crankset
  1. DrD (verified owner)

    I am a big fan of SRAM Red AXS eTap in the first place, which came with my S-Works Roubaix in 2020 (before they change all the models of Roubaix). I wanted to change out the chainrings to a larger size as well as crank size. Because no one really looks into crank length before buying (unless it is a custom made bike), everyone gets 172.5, unless it’s a woman’s bike. Check into what crank length you really need. Also, the same goes for chainring sizes. I wish I would have had the 48/35 in the first place, but so be it. With the matched cassette, SRAM did a good job on their picks, and the same goes for the 48/35. At 48/10 and cadence of 110, you’ll be going around 35-38 mph, suitable for most situations. If I wasn’t living in an area where I get grades >10%, I might have chosen the 50/37, especially f I was competing in flats, rollers, or time trials. Taking the old one out and putting the new one in was as simple as it gets, and only a slight height adjustment in the front derailleur was needed. I had previously changed out all bearings and rear pulleys to Ceramic Speed, but not sure it was worth it, although I do like them.
