SRAM RED AXS Quarq D1 Power Meter Crankset 50-37 Teeth Dub black

The QUARQ Red AXS Powermeter crankset breaks with tradition and achieves a new level of performance. In a way, the road drive has been reinvented: with smaller chainrings and an extended gear step. All chainring sets come with a difference of 13 teeth, which guarantees precise shifting for each setup. This Red AXS crank also features fully integrated, original QUARQ power measurement technology.

AXS
Control and individualization. AXS is the latest system to integrate bike components and takes the wireless switching of eTap to a new level. The SRAM AXS App allows the rider not only to check the battery status and change the shifting behaviour. It can also be used to customise controllers, receive maintenance reminders and retrieve firmware updates.

DZero
DZero is QUARQ's next generation power meter, named after the DZero Experiment, one of the most accurate and innovative scientific projects to discover subatomic particles. With a revised measurement loop, optimized strain gage design, increased accuracy and advanced software, DZero represents the state of the art in power meter technology. You can choose between Bluetooth LE and ANT+ technology for data transfer.

X-Range
Racing bikes are faster and more powerful than ever before and riders keep showing what bikes with racing handlebars are capable of. X-Range offers a wider range of gear ratios, as well as an even more pleasant and usable gear gradation... and also has smart, programmable shift settings thanks to AXS.

DUB
The new SRAM DUB bottom bracket series has a simple job—connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, SRAM engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride.
