Superior XR GR is Czech Bikemaker's Fastest, Lightest, Most Aero Gravel Bike Ever
Briefly

Superior is excited about the XR gravel bike, marking a significant performance and versatility upgrade from the X-Road model introduced in 2016, with a focus on lightweight gravel frame technology and improved stiffness, power transfer, and handling.
Key changes include aerodynamic optimizations like integrated fork crown-to-downtube shaping, deeper airfoil tube shapes, increased tire clearance up to 45mm for versatility in tire choices, and fully internal cable routing for a sleek look and improved aerodynamics.
