The SRAM RED AXS road brake caliper is a high-performance option that combines aerodynamic design with powerful braking capabilities. Its AeroLink arm increases braking power while reducing the frontal area, and the indexed four-position quick release is designed with an aero shape. The brake caliper also features lighter and aero pad retainers that come with SwissStop Flash Pro pads as standard. Additionally, the wider clearance of the caliper allows for modern tires and wheelsets up to 28c.
