SRAM Red D1 DUB 2x12-speed Crank 46/33

The SRAM RED® crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. This leads to smoother and faster shifting up front and more useful gearing. The new configurations improve cadence and efficiency while also delivering shifts that are crisp, clean and quick—every time.

A new chapter in crank set design: the Red DUB 2x12-speed crank from Sram

In order to design a better product, you sometimes have to let go of tradition. By shifting the gear range from front to rear and maintaining a consistent 13-tooth spacing for all 2-speed chainring variants, Sram has been able to improve the Red crank's shifting performance and give drivers the gear ratio they really want and need. A prime example is the SRAM RED® crankset. The SRAM RED® crankset was specially developed for electronic shifting and is a big step forward in crankset design.

Technologies

DeepRange™
Racers and their drivers are faster and more efficient than ever before. But the translation of our cars has not kept pace with this change. It has been limited by tradition. With the sole aim of improving the modern riding experience on the road, Sram has completely redesigned the road bike ratio. The new Deep Range technology. Not only does it offer more translation bandwidth, but this bandwidth is also better. It has “depth“: A smoother, more useful gear graduation. Intelligent shift settings, made possible by AXS™, bring the simplicity of a 1-speed drive to 2 speeds. So you always have the right gear and the translation is not in your way. Drive faster, more efficiently and more comfortably with Deep Range technology.

DUB™
The unit consisting of crankshaft and bottom bracket is the core of the DUB technology. Here stiffness meets durability. Sram is has gone a bit further and made everything even simpler and I've done my job better. It is decisively the system approach through the integration of chainring, crank, shaft and bottom bracket, which means better drive performance.

Exogram™
The new Hollow Carbon Construction starts in the crank arm and extends into the cranks’ spider. It maximizes the stiffness to weight ratio.

X-SYNC™
SRAM X-SYNC™ chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1x™ drivetrain.
