DT Swiss PHR Washer for Spline One Rims

Because of the Pro Head Reinforcement System (PHR) the washer for Spline One rims (XR, XM and EX) has a larger and more spherical contact area and is designed to balance loads transferred to the rim. The PHR system acts like a ball and socket interface allowing the spoke to pivot and follow the perfect trajectory from hub to rim.
