SRAM RED® Quarq Power Meter

THE HEART OF YOUR BICYCLE

The crankset is the heart of your bicycle and where you’ll find the SRAM RED Quarq power meter. The sole job of the crankset is to convert the effort from both legs to forward motion. It is the perfect place to measure power. 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.

  • A direct force power meter that measures total power output from both legs with +/-1.5% accuracy
  • Works for every discipline: Road, triathlon, time trial, and cyclo-cross
  • No compromises on materials, shifting, wheels, or pedal choice
  • Proven by pro teams and athletes throughout the world – Cobbled Classics, Giro d’Italia, Tour de France, Vuelta a España, World Championships
  • Number 1 at the Ironman World Championship for the last three years
  • Uses a hidden bolt to mount the chainrings – compatible SRAM chainrings ensure the derailment pin lines up behind the crank arm
  • 10K – programmed with over 10,000 data points to eliminate temperature effects on power measurement
  • AxCad – A multi-axis accelerometer switches the power meter on and measures cadence, simplifying installation and operation
  • Breakthrough Materials – Exogram™ hollow carbon fiber crank arms – the lightest, strongest crank arms we make – minimize weight and maximize speed [ELSA RS, ELSA R and SRAM RED]
  • Easy to use (and reuse) – LED indicator and visible ANT+ ID
  • The replaceable CR2032 battery never leaves you without power
  • Manual and automatic zeroing make it truly set and forget

SRAM RED “shifting snaps into gear superbly every time”

“In a world dominated by Shimano, it’s good to be able to ride SRAM Red again. It’s easy to forget just how slick SRAM’s top-end groupset actually is. The Double Tap shifting snaps into gear superbly every time, and the speed with which you can ship across the block and the smoothness of the trim-free Yaw front derailleur are both marvels. Oh, and it’s also the lightest groupset out there. Impressive.

SRAM's Wireless Shifting Will Revolutionize Your Road Bike - Men's Journal

"After spending three months riding it, it’s safe to say that eTap is a truly revolutionary component group that raises the bar for what an electronic drivetrain can be. And it may even redefine the way we shift our bikes."

Bike Company Switches Gears in Road Shifting, Going Wireless | The New York Times

"But SRAM’s new offering, Red eTap, effectively turns bikes into micronetworks that allow shifting that is both wireless and electronic."

 

"Despite wireless advances since then, SRAM quickly discovered that off-the-shelf wireless systems were not up to the job. With Bluetooth, for example, there was too great a time lag. Other systems strained batteries. As a result, SRAM was left to come up with a wireless system of its own."
