The MKII is the result of two years of focused and intense development, combining the latest in carbon materials design and manufacture to achieve a wheel that is the lightest in its class today.
The new MKII R-series is the ultimate performance road wheel for training and competition. With the highest lateral stiffness (~55/mm) in its class, the MKII delivers exceptional ride comfort and responsiveness for the discerning rider.
Partington spokes are produced using a highly-guarded, proprietary manufacturing process. 108,000 continuous filaments carry the tension of the spoke as it exits the rim, wraps around the hub, and terminates back at the rim – maintaining load throughout, and minimizing stresses at the spoke to hub junction.
