SRAM RED eTap Power Meter


Developed hand-in-hand with SRAM RED 22, the remodeled RED Power Meter receives Exogram™ hollow carbon crank arms and 162.5mm and 165mm crank lengths. It features an LED that signals power on and zeroing, a visible ANT+™ ID and tool-free, user-replaceable CR2032 battery. Add 1.5% accuracy, Power Balance™ and OmniCal™ and you get a versatile and lightweight package filled with cutting edge technology that amplifies any rider's performance.


  • Available in 162.5mm – 177.5mm lengths and built on Quarq’s current technology platform:
  • Power measurement in the crankset spider — the heart of your bicycle, its sole job is to convert the effort from both legs to forward motion.
  • 10K™ temperature compensation eliminates temperature effects on power measurement.
  • AxCad™ accelerometer cadence removes the need for a magnet.
  • An LED and visible ANT+™ ID streamline installation and operation.
  • OmniCal™ means you can change chainrings without affecting accuracy.
  • CR2032 battery – 300 hours of riding time.
  • ANT+™
  • +/- 1.5% accuracy
  • Exogram™ Hollow Carbon crank arms
  • Power Balance™
  • Quarq power meters have an IPX7 waterproof rating. They feature a 2-year warranty, free firmware updates and      Quarq’s acclaimed worldwide support.


  • The SRAM RED Quarq power meter was tested to ensure smooth, precise shifting with SRAM's new RED eTap groupset and gets new graphics to complete the look.
  • This power meter works for every discipline: Road, triathlon, time trial and cyclo-cross. The chainrings are replaceable should your bike, discipline or ability change.
  • The RED power meter uses a hidden bolt to mount the chainrings. Compatible SRAM chainrings ensure the derailment pin lines up behind the crank arm.
