SRAM Red AXS E1 DUB 2x12-Speed Crankset

SRAM are not ones to rest on their laurels. So when they found ways to make their lightest and stiffest crank even lighter, they went for it. A new optimised layup drops further grams from the hollow carbon arms, and to stay on top of current fit trends they’ve added their first carbon 160mm crankarm length option. And X-Range gearing keeps your cadence change during a front shift to the minimum, maximising your ability to put power down.

SRAM Red AXS E1 DUB 2×12-Speed Crankset

This SRAM Red E1 DUB crankset with hollow carbon arms is the ideal addition to the 2×12-speed drivetrain of your road bike. The one-piece construction is not only 29 g lighter than its predecessor, but 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.

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.
