SRAM RED AXS Power Meter Crankset

The SRAM RED AXS Power Meter Crankset uses Quarq’s premier DZero power measurement technology which promises accurate and consistent power readings regardless of the climate or conditions. This power meter also features dual ANT+ and Bluetooth SMART, left and right power balance and a full 2-year warranty.

In addition to a premier SRAM power meter, you also get a top of the line crankset. The SRAM RED crank offers both strength and stiffness due to SRAM’s proprietary carbon lay-up design. The crankset also uses a unique integrated chainring design which further increasing stiffness. Even better…weight is kept to a minimum. In fact, the refined carbon architecture ensures the greatest weight savings possible. The complete crankset (170 mm, 50/37) weighs in at just 630 grams!

 

Key Product Details

Compatibility:

This power meter crankset is compatible with SRAM DUB or GXP bottom brackets (based on the spindle type selected). 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 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 nicest, but also most expensive, 2x road power meter. It features their high-end carbon RED cranks and a 1-piece fully integrated power meter spider and chainrings, which makes it lightweight and stiff. We also like that the power meter measures power from both legs as well as provides left vs. right power balance. One thing to note – 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 solid piece. Most customers however can get many years of life out of the power meter before it needs to be replaced.

 

Options For This Power Meter

  • Chainrings: 46/33 | 48/35 | 50/37
  • Crank arm lengths: 165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm
  • Spindle Type: These crank arms are available with a DUB (29.9 mm) or GXP spindle (22/24 mm). Please make sure you have the correct bottom bracket on your bike.

 

Other Versions to Consider

Power Meter Only: If you already have SRAM RED AXS crank arms, you can buy the SRAM RED AXS Power Meter Spider and bolt it up to your existing cranks. (However, please make sure you have the latest version SRAM RED AXS crank arms as the older generation RED crank arms won’t work.)

1 review for SRAM RED 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.
