Sram Red DUB 2x12v DM 48-35 crankset
The new Sram Red® crankset features a fundamental design innovation: smaller chainrings, a wider range of ratios and even lighter and stronger cranks. The new chainring interface favours smoother and faster shifting, - an innovation that will satisfy even the most demanding cyclists. Thanks to this, the new configurations improve pedalling efficiency while offering a safe and quiet ride.

Technologies
X-Range
Racing bikes have become faster and more versatile than ever over the years, and cyclists are expanding the range of possibilities with a road bike. X-Range™ is an innovation for today's cyclists. Developments for road bikes have been completely rethought to offer a wider and more progressive range, while offering more intelligent gear shifting parameters. With X-Range™, you will be sure to always choose the best gear ratio.
DUB
Sram DUB™ bottom bracket and crankset technology is a tireless workhorse, forward-looking yet backward-compatible. It is designed for the most demanding pros and for those who want to use it and forget it exists. DUB™ is compatible with the most important bottom bracket standards and can be mounted on any frame without having to make any compromises. In addition, it opens the door to a new type of axle for the lightest crankset ever produced. A new method that combines the best features of the existing GXP and BB30, offering exceptional bearing life without sacrificing the rigidity of thicker axles.
