SRAM RED AXS Quarq D1 Power Meter Crankset 50T DUB black

In certain disciplines, the single-ring drivetrain reigns supreme. Championing simplicity, strength and durability, the SRAM RED 1 AXS power meter meets the demands of triathletes, time trialists and cyclocross racers. The power meter features improved aerodynamics thanks to direct mount aero chainrings with fully integrated power, and the tighter gearing range is perfect for racing and flatter terrains.

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-Sync
X-Sync 1x chainrings from SRAM ensure maximum performance and durability. The long SRAM X-Sync tooth edges grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded bevel edges support the chain guide. To provide the best possible performance even in muddy terrain, the X-Sync chainrings have recesses to remove dirt and mud from the inner chain links and rollers.

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.
