{"title":"Partington Wheels","description":"\u003cp\u003ePartington Wheels are engineered in Australia with a singular goal: to create the world’s most advanced carbon road wheels. Known for precision design, aerodynamic efficiency, and feather-light construction, Partington pushes beyond conventional wheelbuilding by combining cutting-edge composites with meticulous craftsmanship. Every wheel is designed to deliver explosive acceleration, razor-sharp handling, and the confidence riders demand at the highest level of cycling.\u003c\/p\u003e\n\n\u003cp\u003eThe flagship R-Series, including the MKII R39\/44 and R31, offers a unique blend of low weight and strength with rim profiles tuned for real-world performance. Riders experience unmatched responsiveness on climbs, stability on descents, and reduced drag in changing wind conditions. The Gold Edition R-Series MKII elevates this performance even further, combining limited-edition finishes with all the speed and stiffness that makes Partington one of the most sought-after names in the peloton.\u003c\/p\u003e\n\n\u003cp\u003eWhether you’re racing, climbing, or chasing personal bests, Partington wheels deliver a ride quality unlike anything else. With advanced carbon layups, unique hub integration, and aerodynamic rim shaping, these wheels redefine what’s possible for serious cyclists who demand the best.\u003c\/p\u003e","products":[{"product_id":"partington-r-series-mkii-r39-44-wheelset","title":"Partington R-Series MKII R39\/44 Wheelset","description":"\u003cdiv\u003e\n  \u003cp\u003eThe \u003cstrong\u003ePartington R-Series MKII R39\/44 Wheelset\u003c\/strong\u003e comes out of a small factory in Waurn Ponds on the outskirts of Geelong, Victoria, where Partington designs, develops, and manufactures every component in-house — with one exception. The CeramicSpeed bearings are the only part that doesn't originate in the building. The rims, the hub shells, and the spokes are all Partington's own work, built using proprietary carbon construction and manufacturing processes developed over two years of focused engineering.\u003c\/p\u003e\n\n  \u003cp\u003eThe result is one of the lightest disc brake wheelsets at this rim depth: 530g front, 630g rear, 1,160g for the pair, with a lateral stiffness rating of approximately 55 N\/mm. Partington's position is that no other clincher wheelset achieves both numbers simultaneously at this weight — and the spoke design is central to why.\u003c\/p\u003e\n\n  \u003ch3\u003eIn-Tension Spoke Technology\u003c\/h3\u003e\n  \u003cp\u003eRather than conventional spokes that terminate at a hub flange, Partington's spokes travel from one side of the rim, wrap continuously around the hub, and terminate back at the same rim — a U-shaped, rim-to-rim path that eliminates the spoke-to-hub junction entirely. 108,000 continuous carbon filaments carry the tension of each spoke across this arc, maintaining load throughout rather than concentrating stress at a single mechanical interface. The result is a system that is structurally more efficient, and one that removes a common point of fatigue failure in traditional carbon spoke wheels.\u003c\/p\u003e\n\n  \u003cp\u003eThe spokes themselves are asymmetrically bladed full carbon — 20 per wheel, in what Partington designates a \"20-hole rim\" based on the rim termination points. The bladed profile reduces aerodynamic drag, while the rim-to-rim filament path preserves fiber continuity and load direction. The hub shell is a hybrid composite structure housing CeramicSpeed bearings in a newly developed bearing architecture — a component that Cadel Evans, the 2011 Tour de France winner, described simply as \"art.\"\u003c\/p\u003e\n\n  \u003ch3\u003e39\/44 Asymmetric Depth Configuration\u003c\/h3\u003e\n  \u003cp\u003eThe mismatched rim depths are deliberate. The 39mm front wheel is sized for crosswind stability — where the front wheel's position amplifies any lateral aerodynamic force and where handling sensitivity is highest. The 44mm rear sits in a more aerodynamically protected position behind the rider and frame, where greater depth returns more aerodynamic benefit without affecting handling. Together, the pair delivers more aero efficiency than a matched 39\/39 setup without the handling compromise of a matched 44\/44.\u003c\/p\u003e\n\n  \u003cp\u003eBoth rims share a 21mm internal width and 26.5mm external width, optimized for tires in the 25–32mm range. The rim bed is tubeless-ready and factory-sealed — no tubeless tape required. Traditional clincher setups run equally cleanly. Both wheels use 12mm through-axles, and the freehub is swappable across Campagnolo, Shimano HG11, and SRAM XDR standards.
