A HIGH-SPEED CRIT AND ROAD RACE WEAPON THAT CUTS THROUGH THE WIND BUT HANDLES LIKE A SHALLOWER RIM, ALLOWING YOU TO MAINTAIN YOUR AERO POSITION THROUGH VARIABLE CONDITIONS.

The wind tunnel results below shows that the HUNT 60 Limitless Aero Disc offers comparable performance against a number of leading aerodynamic wheel manufacturers. When paired with the optimal Schwalbe Pro One 28mm tire the wheels were the 3rd fastest wheelset on the market at the time of testing.

The power data from the tunnel was analysed with a set of yaw angle weightings, independently published by MAVIC, showing that the wind averaged power difference is as minimal as 0.35W between the HUNT 60 Limitless Aero Disc and ENVE 5.6 SES DISC and 0.22W between HUNT 60 Limitless Aero Disc and ROVAL RAPIDE CLX. The testing sessions also found that the 60 Limitless Aero Disc outperforms some deeper, highly considered wheelsets on the market.

The Steering Moment analysis confirms the predictable and stable handling characteristics of the HUNT 60 Limitless Aero Disc, particularly at yaw angles greater than 10 degrees. For a number of the competitors wheelsets, significant changes in the steering moment curve gradient are observed in the region of 10 degrees yaw, which could result in unpredictable forces felt when encountering changes in wind direction at higher yaw angles such as cornering hard into the final turn of a sprint or turning onto Queen Ka’ahumanu Highway heading back into Kailua-Kona.

Cross Wind Stability

Many riders are familiar with the unsettling feeling of turning onto an unprotected road and immediately getting hit with a strong gust of wind; your heart skips a beat for half a second and you grip the bars a little tighter as you regain your confidence. With the development of the 60 Limitless Aero Disc, HUNT set out to make a wheelset that could have smooth and consistent airflow around the rim when you need it most.

As first explored in the testing of the 42 Limitless Gravel Disc, HUNT monitors various elements of aerodynamic performance, including side forces that act on the rims, and the effect those forces have on the steering moment. As with our previous projects, our wheels are tested through a range of effective yaw angles between negative 20 degrees and positive 20 degrees.

Concluded in the white paper attached, the steering moment analysis on the 60 Limitless Aero Disc and its closest competitors confirms predictable and stable handling characteristics. Most notably when the yaw angles are greater than 10 degrees. In the analysis, one can see that there are significant changes in the steering moment curve gradient when in the region of 10 degrees yaw, which could result in unpredictable forces felt when encountering changes in wind direction at higher yaw angles. These changes in wind direction occur numerous times when riding through a city, as wind constantly changes in direction and magnitude as it is pushed up, around and down off of buildings resulting in often chaotic wind flow.
