The 50mm depth is engineered for racing, prioritising aerodynamics over the shallower 38mm option.
As a daily wheelset, it suits riders in areas without persistent high winds—though experienced riders accustomed to deep-section wheels can confidently use the GMR 50 in any conditions. Optimised for wide tyres at lower pressures, the GMR 50 Tubeless Rim-Brake delivers the low rolling resistance and compliance modern riders demand. Its 19mm internal width excels on rough roads and performs fastest with a 28mm tyre across most wind angles.
