Hunt has launched the 5AM Limitless Ti_UD Carbon Spoke Wheelset, a flagship aero road wheelset with front and rear specific rim profiles, with a claimed weight of 1,212g per pair, and pricing that starts at £1,999 / $2,599 / €2,349.
The wheelset is available for pre-order now, with stock due to ship from Hunt's facilities in West Sussex, Boulder (Colorado) and Dresden in the third week of May 2026.
The launch marks a deliberate repositioning for Hunt. The brand built its reputation on strong performance at accessible prices, but the 5AM Limitless asks to be judged on a different basis: direct aerodynamic competition with established premium wheels from ENVE, Roval, Zipp and Scope. Hunt says wind tunnel and outdoor testing shows the 5AM Limitless is faster than all four, though those results come from the company's own testing rather than independent verification.
Front rim (left) is deeper and wider than the rear to meet cleaner airflow first.
The wheel market in 2026 is mature and squeezed from both ends. At the top, brands like ENVE and Roval sell deep engineering stories alongside premium pricing. At the bottom, cheaper Far Eastern manufacturers can now deliver competent aero carbon wheels at aggressive prices. Hunt's response is not to undercut on price but to compete on design methodology, publishing unusually detailed comparisons and a multi-stage testing process to argue that its wheels belong alongside the category leaders.

The front wheel is deeper (58mm) and wider (34.5mm external) because it meets cleaner, more laminar airflow first, making it the most aero-sensitive wheel in the system.
Hunt uses a patented "Limitless Width" construction here, moulding low-density structural polymer (0.7g/cm³) into the rim sidewall between carbon layers (1.6g/cm³) to achieve a wider, blunt profile without a proportional weight penalty. The wider shape is designed to keep airflow attached at higher yaw angles and to condition the air before it reaches the frame's downtube.
The rear wheel is shallower (55mm) and narrower (30mm external). Hunt's reasoning is that the rear wheel sits in turbulent air behind the rider, frame and front wheel, where absolute drag reduction matters less than weight and power transfer. It runs 18 spokes to the front wheel's 15 and uses a narrower rim to save mass. Both wheels share a 23mm internal width and hooked bead, making them ETRTO-compliant with 28–50mm tyres in tubeless or clincher setups, though the aerodynamic optimisation targets 28–30mm rubber.
The spokes are Vonoa Ti_UD carbon, each weighing 1.7g with titanium Ti6-4AL-4V hardware. Hunt claims tensile strength above 400kgf per spoke, compared with around 290–300kgf for high-end steel spokes. The front wheel uses internal spoke nipples to reduce rotational drag, a design choice that trades serviceability for aerodynamic gain.
Rims are built from a blend of T700, T800 and T1000 UD carbon fibres combined with Mitsubishi Pyrofil HR4012M high-modulus carbon. The hub is Hunt's own Chase SLC, CNC-machined from 7075-T6 aluminium, with a 48-tooth ratchet drive system offering 7.5° engagement. Buyers can choose between standard stainless steel bearings or yet-to-be-released CeramicSpeed hybrid-ceramic bearings, the latter pushing the price to £2,489 / $3,199 / €2,899.
What Hunt's test data says
Hunt's headline comparison is a claimed 4.35-watt advantage over the ENVE 4.5 Pro in wind tunnel testing with 30mm tyres. The company also says it measured a 1.74-watt gain over the Roval Rapide Sprint and a 1.99-watt gain over the Scope Artech 6 in the same tunnel conditions.

Outdoor testing, conducted with Dr Barnaby Garrood at AeroSensor, produced even larger numbers. Hunt claims an 8.5-watt advantage over the Zipp 404 Firecrest (which runs 24 spokes front and rear) and a 5.9-watt advantage over the Scope Artech 6 (18 front / 24 rear spokes) with 30mm tyres. Hunt attributes the bigger outdoor gains to reduced rotational drag from fewer, lighter spokes and hidden nipples, a factor it says is difficult to isolate in a wind tunnel because tunnel rigs typically drive the wheel rather than measuring the full power balance of a rolling, pedalling system.
Garrood, described by AeroSensor as a former Formula 1 aerodynamicist, uses a portable system that calculates aerodynamic drag by measuring the other power terms in the rider-bike system and deriving CdA from the remaining power balance. That approach captures real-world variables, including road surface, wind gusts and rider movement, but it also introduces more noise than a controlled tunnel environment.
We're yet to get our hands on a set for testing, but we'll be interested to see how the claims translate into real world speed and ride feel, and whether we can verify any of the numbers ourselves.
