Sram Group XX1 Eagle Black 12v DUB

Sram revolutionizes the world of MTB again: here is the 12-speed transmission Sram XX1 Eagle Black with the new universal DUB crankset, suitable for all types of frames.

DUB TECHNOLOGY
The new DUB technology revolutionizes the crank / frame ratio: a single crank and a single central pin.
With DUB the combination of frame, bottom bracket and crankset is simple, and all components are stronger, stiffer and more durable. A significant improvement for the entire transmission.
DUB replaces the previous GXP and BB30 versions and introduces a new pin with a diameter of 28.9 mm.
A DUB crankset can be interfaced with any frame using the right bottom bracket.

There are many advantages of a 12-speed transmission:

- Wide gear range thanks to 50-tooth pinion
- No front derailleur
- Lighter weight
- Greater ease of use
- Better pedaling efficiency
- Compatible with most frames
- No new standards introduced (only requires the SRAM type bodice XD)
