SRAM S7 internal gear hub

SRAM S7 is a seven-speed internal gear hub for bicycles, originally developed under the Sachs brand. The product lineage is deeply rooted in German engineering, tracing back to the Fichtel & Sachs company, which was a pioneer in bicycle hub technology. Following SRAM's acquisition of the Sachs Bicycle Components division in 1997, the hub was rebranded and further integrated into SRAM's global product portfolio.

Today, SRAM is an American privately owned bicycle component manufacturer based in Chicago. While the S7 hub has historical manufacturing roots in Schweinfurt, Germany, SRAM utilizes a global manufacturing network including facilities in Taiwan, China, and Portugal. The S7 series remains a classic example of German design meeting modern American industrial ownership, serving the commuter and trekking bike markets worldwide.
