R-Series Technology
The R-Series introduces a series of innovations that will propel us into the future.
The R-Series introduces a series of innovations that will propel us into the future.
The R-SERIES wheelset is a reset of our thinking and design concepts for high-performance carbon-fiber road bicycle wheelsets.
Our new R-Series Wheelsets underwent extensive wind tunnel and real-world testing to ensure they perform on every ride.
Every component of the R-Series wheelset is intended to operate as a system.
Our system engineering approach ensures that our wheels are designed to perform.
We only design, develop, test and manufacture high-performance carbon-fiber bicycle wheels.
"The R-Series PERFORMANCE and PERFORMANCE Ti wheelsets are not a step change but a complete re-design to create a wheelset that delivers on every ride."
Jon Partington, Founder and CEO of Partnington
Innovation: floating bearing architecture
A significant element of the new Partington R-Series PERFORMANCE AND PERFORMANCE Ti wheelset hub design is the bearing arrangement, which differs from configurations found in many other wheel hubs.
Partington's objective during the design phase was to ensure that the bearings were configured in a manner that enables lowest rolling friction, highest bearing life and best distribution of loads to contribute to a stiff wheel architecture.
Improved rolling performance versus conventional configurations, providing a platform for performance through wheelset stiffness.
INNOVATION: FOAM CORE
For the all-new Partington R-Series PERFORMANCE and PERFORMANCE Ti wheelsets, we have opted for a foam-core construction to enhance overall performance.
The foam-core construction provides several benefits: the foam's natural vibration-attenuating properties noticeably reduce road-borne vibrations, reducing rider fatigue and improving comfort on rough roads. Furthermore, the foam core stabilizes the carbon fiber structure, allowing the laminate architecture to be tailored to increase radial compliance and enhance rider comfort.
INNOVATION: AERO PERFORMANCE
At Partington, our rim profiles are designed to generate smooth, stable aerodynamic forces in all wind conditions, helping riders maintain confidence when conditions become challenging.
Using extensive CFD analysis and wind tunnel testing, we focused on not only aerodynamic efficiency but also steering neutrality. By carefully balancing aerodynamic forces around the steering axis, our wheels reduce steering disturbances while retaining the speed benefits of the sailing effect.
Speed is only valuable when it remains predictable and controllable. Our new R-Series PERFORMANCE and PERFORMANCE Ti wheelsets feel calmer in crosswinds, requiring fewer steering corrections, allowing the rider to stay focused on riding fast.
INNOVATION: NEW RATCHET TECHNOLOGY
For the all-new Partington R-Series PERFORMANCE and PERFORMANCE Ti wheelsets, we have redesigned our ratchet with improved engagement and power delivery.
Our new ratchet is our highest-performance system yet. With 68 engagement points, a 38% increase over our MKII wheelsets, it ensures power is transferred to the road the moment you demand it.
Combined with a helical drive system that promotes positive ratchet engagement under the highest loads, it delivers exceptional responsiveness while keeping freewheeling drag to a minimum.
The efficient and responsive transmission of a rider's power through the rear wheel is essential to realizing every possible watt on every ride.
Through extensive CFD, wind tunnel, and real-world testing, we have developed a new architecture for the R-Series wheelset. Featuring a new rim shape, composite spokes, and a new hub. These components were designed to operate as a system.
Partington AERON Carbon Fiber Rim features Multi-Material Composite utilizing Premium Toray Fibers with PMI foam core. The R-Series rim shapes have been developed internally and refined at the SASI Wind Tunnel in Adelaide, Australia, and through extensive CFD analysis.
Partington’s FLEXON composite spokes are manufactured using continuous, uninterrupted Toray intermediate-modulus, high tensile strength carbon fibers to provide excellent strength, fatigue life, while providing world class lateral stiffness.
The Partington PERFORM hub was engineered using detailed Finite Element Analysis (FEA) to refine structural geometry, reduce mass while maintaining stiffness and ensuring efficient load transfer in real world conditions.
