Sram offers a full range of groupsets and components for your bike. Many consider Sram the American counterpart to Shimano. Sram has been known for producing the lightest groupset on the market for years now: Sram RED. Over the last couple of years, Sram has been at the forefront of innovation when it comes to the x1 groupsets, spearheaded by the Sram Eagle drivetrain. This latest invention has considerably raised the bar by introducing 12-speed to mountain biking!
