SRAM
Road SRAM
Sram, founded in 1987 in the USA, has brought many revolutionary solutions through the years. While the brand flourished, they took other brands under their wings, such as Sachs, Rock Shox, Avid, Truvativ, Zipp or Quarq. At the beginning of the new millennium, Sram focused on components for road cycling while beating concurrence with electronic wireless switching.
