The history of the SRAM company begins back in 1987 with the opening of a small workshop and office for the production and assembly of bicycles from third-party components. At that time, the company’s staff consisted of 6 people. The company’s office was located in Chicago, USA. Over the course of several years, the designers of the SRAM company began to produce their inexpensive bicycle parts, in particular, the branded SRAM shifters for road bikes.
