SRAM RED® DZero Power Meter
REACH A HIGHER LEVEL
Quarq’s next-generation power meter platform, DZero, is named for the DZero Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light.
With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke and software advances built into the Qalvin App, DZero represents the state of the art in power meter technology.
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
- Dual Bluetooth low energy and ANT+ let you choose how to capture the data
- 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
- 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
- Built to Last – IPX7 waterproof rating, 2-year warranty, free firmware updates, and acclaimed international support
- Moves with you from bike to bike
- With Quarq's free Qalvin BLE mobile app – available for iOS® and Android – you can set the zero offset, check battery voltage, run diagnostics, and perform firmware updates

The new Hollow Carbon Construction starts in the crank arm and extends into the cranks’ spider. It maximizes the stiffness to weight ratio.
Quarq technology powers SRAM’s road power meters including the groundbreaking SRAM RED Quarq Power Meter.
- X-GlideR Chainrings
The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.

"On top of the great price and performance a two year warranty will give you piece of mind, a great job by Quarq."
“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.”
"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."
"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."
