Princeton Carbon Works Peak 4550 Evo Tactic Hub Wheelset The Princeton Carbon Works Peak 4550 Evolution Wheelset builds on the advancements of the Wake 6560 Evolution and Alta 3532, raising performance to new heights. With an increased internal rim width of 21mm (28.2mm external) and a reduced rim weight of just 420g, the Peak 4550 Evolution achieves improved stiffness, balance, and aerodynamic efficiency, thanks to the patented Radially Staggered Lacing. The wheelset now features a graphic design similar to the Wake 6560 Evolution, offering a cohesive aesthetic for staggered Peak/Wake setups. The Peak 4550 Evolution retains a hooked, hole-less, tubeless-ready tyre bed, accommodating both clincher and tubeless tyres without the need for tape or tyre pressure restrictions. Unlike hookless rims, which may pose tyre compatibility and safety issues, the hooked rim design ensures the safest and fastest solution for road riding and racing. All builds include Sapim CX-Ray spokes and Tactic Racing Hubs, ensuring exceptional quality and performance. Exceptional handling, ultra-lightweight construction, and unmatched versatility make the Peak 4550 Evolution a true King of the Mountain. Designed to excel in every aspect, this wheelset offers rapid acceleration for climbs, sharp and predictable handling for descents, and aerodynamic stability in crosswinds for the flats. The non-drilled tyre bed design enhances stiffness by reinforcing the outer rim, while redistributing material to critical areas to maintain low weight and high durability. A wheelset for riders seeking the pinnacle of performance on every terrain.
