SRAM Red 1 E1 AXS Aero DUB 1x12-speed Carbon Power Meter Crankset

The Red 1 AXS E1 Aero DUB 1x12-speed power meter crankset from SRAM with carbon arms - measurable performance for road bikes

This SRAM Red E1 DUB crankset with hollow carbon arms, aerodynamic chainring and integrated power meter is the ideal addition to the 1x12-speed drivetrain of your road bike. It not only has 29 g lighter crank arms than its predecessor, but is also stiffer and sturdier. The X-Range technology promises precise and smooth shifting with a wide range. Thanks to DUB technology, the crankset is extremely durable and perfectly matched to DUB bottom brackets.

Technology:

AXS
AXS is SRAM's electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows you to view battery status, change component behaviour, adjust controls, receive maintenance reminders and update firmware.

DUB
The unit of crankshaft and bottom bracket is the heart of the DUB technology. Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is mainly the system approach through the integration of chainring, crank, spindle and bottom bracket that means better drivetrain performance.

X-Range
The X-Range technology was developed with the possibilities of today's dropbar bikes in mind. It is distinguished by a broad gear range with smooth, even gear changes. The combination of chainrings with 13-tooth spacing with a high bandwidth cassette, starting with a 10-tooth sprocket, ensures well thought-out, homogeneous gear jumps and always puts you in the right gear. In combination with AXS, you can make various shift settings and personalise your drivetrain to suit you.
