Technology

DZERO™

Quarq’s next-generation DZero power meter platform is named for the D0 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, DZero represents the state of the art in power meter technology.

 

AXS™ 

AXS is SRAM’s new electronic integration platform that connects electronic bicycle components and software. The SRAM AXS App allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.

 

X-SYNC™ 

SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x™ drivetrain. Accept no imitations.

 

CARBON TUNED™ 

Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

 

X-RANGE™ 

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. We completely re-imagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings – enabled by AXS™ App. With X-Range, you’re always in the right gear.

FAQ

When power meter-equipped SRAM RED® 2x road chainrings wear out, does the power meter have to be replaced?

Yes. The power meter on SRAM RED® chainring sets is fully integrated with the chainrings for the lowest possible weight and the highest possible accuracy. However, RED® chainrings are made to last 50% longer than our 11-speed chainrings to greatly extend the life of the ring and power meter assembly. Additionally, regular chain cleaning, lubrication, and timely replacement when worn will greatly improve the lifespan of the chainrings. Staying on top of this preventative maintenance will also keep your drivetrain performing well while saving you money on replacement chainrings. When it’s time to replace your integrated power meter, you can contact SRAM for a half-price replacement, and we will recycle your old one.

Do RED® chainrings last as long as SRAM’s 11-speed chainrings, or will they last longer?

SRAM RED® chainrings have a 50% reduction in wear which means they will last 50% longer than 11-speed chainrings
