Hunt’s latest innovation, the 4AM Limitless Ti_UD Carbon Spoke wheelset, redefines the boundaries of ultralight and aerodynamic performance. Weighing a mere 1,156 grams, these wheels are engineered to deliver exceptional speed and responsiveness, making them a formidable choice for competitive cyclists.<\/p>\n
Design and Construction<\/strong><\/p>\n The 4AM wheelset features front and rear rims with depths of 49.5mm and 47mm, respectively, and external widths of 34.2mm and 30mm. This configuration strikes an optimal balance between aerodynamic efficiency and weight reduction. Hunt’s proprietary Limitless Width Aero Technology incorporates a low-density polymer filler within the rim structure, enhancing aerodynamics without adding significant weight. The rims are constructed using a blend of T700, T800, and T1000 unidirectional carbon fibers, combined with high-modulus Mitsubishi Pyrofil HR 40 12M fiber filler, ensuring both strength and lightness. (us.huntbikewheels.com<\/a>)<\/p>\n Spokes and Hubs<\/strong><\/p>\n Equipped with 15 front and 18 rear Ti_UD Vonoa aero bladed carbon spokes, each weighing just 1.7 grams, the wheelset offers enhanced stiffness and responsiveness. The spokes are secured with 6AL-4V titanium hardware, contributing to the overall reduction in weight. The wheels are fitted with CNC-machined 7075-T6 Hunt Chase SLC centerlock disc brake hubs, featuring a 48-tooth, 7.5\u00b0 engagement H_Ratchet DBL freehub system. Bearings are available in sealed stainless steel or hybrid ceramic configurations, the latter provided by CeramicSpeed, known for their durability and smooth performance. (us.huntbikewheels.com<\/a>)<\/p>\n Aerodynamic Performance<\/strong><\/p>\n Hunt’s comprehensive five-stage development process, encompassing computational fluid dynamics (CFD) modeling, wind tunnel testing, and real-world validation with AeroSensor drag sensors, has optimized the wheelset’s aerodynamic profile. Wind tunnel tests at the Silverstone Sports Engineering Hub indicate that the 4AM Limitless Ti_UD wheelset outperforms the ENVE 4.5 Pro by 1.4 watts while being 139 grams lighter. This performance is achieved through meticulous design and testing, ensuring that the wheels provide a competitive edge in various racing conditions. (us.huntbikewheels.com<\/a>)<\/p>\n Compatibility and Pricing<\/strong><\/p>\n The 4AM Limitless Ti_UD Carbon Spoke wheelset is compatible with 28-50mm tires, supporting both tubeless and clincher setups. The internal rim width of 23mm is optimized for modern 28-30mm tires, aligning with current industry standards. The wheelset is UCI approved, making it suitable for competitive racing. Pricing for the wheelset starts at \u00a32,449 \/ $3,159 \/ \u20ac2,859, reflecting its premium construction and performance capabilities. (us.huntbikewheels.com<\/a>)<\/p>\n In summary, the Hunt 4AM Limitless Ti_UD Carbon Spoke wheelset exemplifies the pinnacle of ultralight and aerodynamic wheel design. Its advanced materials, innovative design, and rigorous testing make it a compelling choice for cyclists seeking to enhance their performance on the road.<\/p>\n
