Breaking through to new levels of performance, the SRAM RED AXS Power Meter Kit features Quarq's premier DZero power measurement technology integrated into the crankset. This power meter spider is designed to upgrade your current non-power AXS crankset to a power meter crankset. Crankarms and spindle do not come with this kit. This kit includes the spider and chainrings only.

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.
