SRAM RED 1x AXS Power Meter Crankset
The SRAM RED 1x AXS Power Meter Crankset is the perfect 1x power meter for triathletes, time trialists and cyclocross racers! Featuring a 1x direct mount aero chainring, the gearing range is perfect for racing and flatter terrains. In addition, Quarq’s premier DZero power measurement technology 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 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 as the refined carbon architecture ensures the greatest weight savings possible.

Advice From Our Staff:
This is SRAM’s nicest, but also most expensive, 1x 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.

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.
