With races sometimes coming down to a hundredth of a second, an aerodynamic chainring like the SRAM RED Aero Chainring is necessary for our drivetrain. This stiff, lightweight aluminum chainring features a unique design ideal for our next trial or triathlon, as well as a laser-etched finish that increases overall durability. Using X-SYNC and X-Range technologies, we are provided with maximum chain control and smooth gear progression to ensure we are always in the proper gear for what's to come.
