SRAM offers a total package of group sets and bicycle parts. This American brand is therefore often seen as a counterpart to Shimano. SRAM has spent many years making fame with the lightest groupset on the market: SRAM Red. In recent years, as an innovator, has often been in the news with the arrival of the x1 groups and the introduction of the SRAM Eagle drivetrain. The latter has clearly raised the bar with the introduction of 12-speed for mountain bikers.
