Hunt has unveiled its latest innovation in high-performance cycling: the 5AM Limitless Ti_UD Carbon Spoke Wheelset. This cutting-edge wheelset is engineered for high-speed road racing on flat and rolling terrains, boasting a claimed weight of just 1,212 grams. (cyclingweekly.com)
Aerodynamic Design
The 5AM Limitless wheelset features a distinctive front and rear rim design. The front rim is 58mm deep and wide, optimized for clean airflow, while the rear rim is 55mm deep and narrower, focusing on weight reduction and efficient power transfer. This configuration aims to maximize aerodynamic efficiency and stability. (bikeradar.com)
Advanced Materials and Construction
Utilizing Hunt’s patented Limitless Width Aero Technology, the front rim incorporates a low-density polymer within the carbon layers. This design maintains a wide aerodynamic profile without adding significant weight, enhancing crosswind stability. The wheelset also employs Vonoa Ti_UD carbon spokes, each weighing 1.7 grams, contributing to reduced rotational drag and increased responsiveness. (cyclist.co.uk)
Hub System and Bearings
The wheels are equipped with Hunt’s Chase SLC hub system, featuring a 48-tooth ratchet drive mechanism with a 7.5° engagement angle for rapid acceleration. Customers can choose between stainless steel bearings or CeramicSpeed hybrid ceramic bearings, the latter offering a lifetime warranty and enhanced performance. (bikeradar.com)
Performance Testing
Through extensive wind tunnel and real-world testing, Hunt claims the 5AM Limitless wheelset outperforms several leading competitors. In wind tunnel tests, it demonstrated a 4.35-watt advantage over the ENVE 4.5 Pro and a 1.74-watt advantage over the Roval Rapide Sprint when fitted with 30mm tires. Outdoor testing revealed a 5.9-watt advantage over the Scope Artech 6 and an 8.5-watt advantage over the Zipp 404 Firecrest at a target speed of 41 km/h. (bikeradar.com)
