welding processes
The welding process produces the most precise, lightest and most stable rim joint. After welding, the joint is plastered to achieve a seamless transition.

Asymmetric
The asymmetric design ensures even tension in the wheel construction and thus an even crisper driving experience.

PHR - Pro Head Reinforcement system
The PHR system increases the load-bearing area of ​​the nipples on the rim and reduces local loads. Peak loads are reduced, making it even easier to build the rim. The shape of the disc also acts as a ball joint and automatically aligns the specific DT Squorx Pro Head Ball Nipples with the spoke, reducing the risk of spoke breakage or rim ripping.
