19_SRAM X01 Eagle 52T Derailleur

Sachs derailleur held true to German engineering! Schweinfurt was the place where they were designed and build (some also in France, in former Huret workshops). And when SRAM bought the Sachs from Mannesmann, Schweinfurt became the European their headquarters and R&D department.

The Sachs Plasma was the first composite derailleur, targeting weight savings.

Designed in the times of Sachs, and release the same year as the acquisition from Sachs by SRAM in 1997.

First models were very unreliable: they broke easily and could hardly be fixed. And compared to Shimano, they lacked shifting precision.

25 years later, SRAM's complete line-up of derailleurs uses composite. They are reliable, easy to service (high end models can be completely disassembled easily and every single piece can be changed).

And these derailleurs were a corner stone of SRAM 1x (1 by) strategy to remove the front shifters and multiple chainrings, supporting 11 speed a now 12 speed cassettes.

X01 models are both light and strong, supporting enduro racing abuse easily.
