Hunt’s newest 5AM Limitless aero wheels reshape their quickest aerodynamically-optimized Limitless carbon street wheelset with front- & rear-specific rims designed to go sooner with trendy 28-30mm extensive tires. And go quick they do. Hunt’s wind tunnel aerodynamics testing reveals vital drag discount from 1.7-4.4W vs. the highest aero wheels from DT, ENVE, Roval, Scope & Reserve. Plus, real-world aero street checks confirmed even larger good points!
However whereas aerodynamics drives their rim shapes, it’s the built-in system engineering method that Hunt took with this mission that retains complete wheelset weight so low. Leveraging a lighter rear rim, UD carbon spokes, and titanium {hardware}, Hunt retains the 5AM Limitless wheels to simply 1212g for the pair – wildly gentle for a 58mm/55mm deep aero wheelset!
Hunt 5AM Limitless ultralight aero wheels with carbon spokes
Hunt says their new 5AM Limitless Ti_UD Carbon Spoke aero street wheels are greatest suited to “excessive pace racing environments on flat and rolling programs”.
However at 1212g, these aerodynamic wheels are lighter than many climbers’ wheels, making for some critically quick all-rounders.
The place does the early morning title come from?
Since their first Limitless wheels in 2019, Hunt has checked out aero wheel design from a extra holistic method. Greater than an aero rim mixed with aero parts, or perhaps a single aero wheel, Hunt has developed their Limitless R&D course of into what they describe as a 5-stage course of:
First, CFD growth.
Then, they undergo three aero optimization steps within the GST & Silverstone wind tunnels: initially, single wheel-only wind tunnel checks to validate CFD knowledge; subsequent, wheel in bike testing to verify wind interplay between wheel, fork & body; and final, wind tunnel testing with an actual pedaling rider to raised approximate actual driving circumstances.
Lastly, Hunt validates their new wheels in real-world out of doors check driving utilizing sensor-based aerodynamic testing with AeroSensor – a key step they are saying quantifies rotational drag impacts precisely, “displaying the spectacular discount… obtain[d] by diminished entrance wheel spoke depend and hidden spoke nipples“.
As for the AM, that comes from the totally different “Aero Maximised” rim profiles entrance & rear.
What’s really new?
On the core of the brand new Hunt 5AM Limitless wheels are two utterly totally different rims with the identical 23mm hooked tubeless internal width. The entrance is 58mm deep x 34.5mm exterior with Hunt’s patented Limitless aero form to maintain airflow connected at increased yaw angles so that you get controllable dealing with & stability, even when racing in difficult wind circumstances. Plus, their particular low-density polymer filler, which lets them construct the rim out extensive like that, with out including numerous further weight. The rear wheel is shallower at 55mm deep, and simply 30mm exterior, the place it cuts by already uneven air, permitting Hunt to save lots of weight on the pair.
By constructing the brand new 5AM Limitless wheels with excessive tensile power, aero-bladed Vonoa Ti_UD carbon spokes (and inside nipples), Hunt was capable of additional scale back weight and spoke depend. They wanted simply 15 carbon spokes up entrance & solely 18 within the again wheel, shaving grams and smoothing airflow in comparison with conventionally-spoked wheels.
How a lot sooner are the brand new Hunt 5AM Limitless wheels?
Hunt is kind of clear of their aerodynamic testing, each sharing the check protocols they used after which sharing their leads to publicly accessible white papers.

“Wind tunnel testing reveals the system 4.35 watts sooner than ENVE 4.5 Professional, and sooner than Roval Rapide Dash and Scope Artech 6 wheels with 30mm tyres.” – within the Silverstone wind tunnel
“Outside testing reveals as much as an 8.5-watt benefit over Zipp 404 Firecrest, and a 5.9-watt benefit over the Scope Artech 6 with 30mm tyres.” – on the Dunsfold runway, with Dr. Barnaby Garrood at AeroSensor
