SRAM's flagship wireless 13-speed gravel groupset with a built-in Quarq power meter, delivering race-precision shifting and braking.
Deep-section, ceramic-bearing carbon wheels (50mm front / 45mm rear) purpose-built for aerodynamic speed on mixed terrain.
A one-piece aero bar/stem that cleans up airflow and cable routing without compromising control on rough gravel.
