Partington R-SERIES MKII R39/44

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.

Composite Wheel System

A high-performance wheel is a system of components that are designed in unison, highly integrated and optimized to work together. Partington's proprietary manufacturing methods produce a completely Integrated Wheel System to produce the world's best performing wheelset.

Dynamic Bearing Architecture

Conventional wheels use bearing arrangements that are often subjected to adverse loads due to use conditions and/or installation arrangements that slow the wheel down. pcc uses a ‘floating’ bearing architecture to ensure there are sufficient Degrees of Freedom such that loads transferred internal to the bearing are minimized and idealized.

In-Tension Spoke Technology

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.
