As one of our widest road rims designs, the WR45 is the answer for the gravel rider trying to squeeze out every aerodynamic advantage from their setup. Designed with racing in mind, the WR45 features a deep U-shape profile that cuts through crosswinds and decreases lateral resistance. With a 45mm deep and stiff profile, the WR50 is designed for experienced bike handlers looking for an aero edge or larger riders.
