Hunt launches lighter 4AM Limitless Ti_UD wheelset with carbon spokes and 1,156g claimed weight

Hunt has launched a new aero wheelset with a deeper, wider front wheel and shallower, narrower rear wheel with carbon spokes, a CeramicSpeed bearing option and a claimed wheelset weight of 1,156g. 

Last month, Hunt introduced the 1,212g 5AM Limitless Ti_UD Carbon Spoke wheelset with mixed 58mm front/55mm rear rim depths.

The latest 4AM Limitless Ti_UD has the same design features but expands the range with a shallower mixed depth wheelset. As with its predecessor, the front rim is deeper and wider externally at 49.5mm depth and 34.2mm width, while the rear has a 47mm depth and 30mm width. 

Hunt says that maximum aero benefits come at the front of the bike, where the airflow is more laminar, while airflow at the rear wheel is turbulent, so aero gains are less but the shallower rim helps keep weight low. It’s the same approach as with the Roval Rapide CLX III wheelset, which also has a deeper front/shallower rear design. Roval has subsequently extended the approach to its Terra Aero CLX gravel wheelset.

The front and rear Hunt 4AM Limitless wheels both have a 23mm internal width hooked rim, the same as for the 5AMs. They’re available with carbon spokes, which hit the claimed 1,156g wheelset weight or with steel spokes, which raise the weight to 1,283g. Hunt has also introduced a steel-spoked version of the 5AM Limitless wheels as a lower-priced alternative to the carbon-spoked wheels available at launch. 

As with the 5AM Limitless wheels, Hunt has developed the latest 4AM wheels via its five stage process, with CFD analysis followed by three iterations of w…
