PHR
TECHNO­LOGY

PHR – Pro Head Reinforcement system. 

The PHR system increases the load-bearing surface of the nipples on the rim and reduces localized stresses. Peak loads are reduced allowing us to build the rim even lighter. The shape of the washer also acts as a ball joint and automatically aligns the specific DT Squorx Pro Head® ball head nipples with the spoke, further reducing the risk of spoke failure or rim cracking.
