Quarq DZero AXS 130BCD DUB Power Meter Crankset Bundle
A crankset power meter must be accurate, reliable and hard-wearing but also completely efficient in transferring the riders effort into forward drive. The Quarq DZero AXS 130BCD DUB Power Meter Crankset Bundle ticks all of these boxes via advanced power measurement, carbon crank arms and DUB axle design.
Possibly the most important feature of a power meter is its preciseness and the DZero’s 1.5% accuracy is industry-leading and allows the rider to perform training sessions efficiently for maximum fitness gains. This accuracy, provided via genuine dual-sided measurement, remains stable even across wide swings in temperature via the 10K Active Temperature Compensation feature and cancels the effects of temperature shifts caused by altitude changes or when riding across different times of the day.
A CR2032 battery powers the unit for up to 200 hours before it needs to be swapped. When this situation does arrive it can be changed easily, tool-free by the user. This battery and all of the sensitive power measurement electronics are housed within the crankset spider and are completely sealed from external elements to a rating of IPX7.
The power readings are transferred to compatible bike computers and smartphones via the ANT+ and Bluetooth protocols before the SRAM AXS app can be easily linked to so that setup, calibration, battery level checks and firmware updates can be performed.
Efficiency and forward drive are catered for via lightweight carbon crank arms and SRAM’s DUB axle, the latter of which enables compatibility with all of SRAM’s latest DUB bottom brackets.
