Hunt’s 5AM Limitless wheels push the limits of speed and stability
A lightweight wheelset designed for spicy group rides or races
Hey, you an early bird? Good news if you like to smash it before work.
Hunt has unveiled the 5AM Limitless Ti_UD Carbon Spoke Wheelset. The new hoops are engineered to deliver speed, control, and efficiency in real-world racing–or training conditions. Either way, they look, feel, and deliver speed.
The setup pairs a 58mm-deep, super-aero front rim with a 55mm rear rim that is made for low weight and power transfer. Plus, the Vonoa Ti_UD carbon spokes reduce rotational drag and boost responsiveness. The total system weighs just 1212 grams. It’s a solid choice for local races, or your early morning group rides (they might even be at 5 a.m.)
According to Hunt, the 5AM Limitless wheels were developed through Hunt’s five-stage aero process.
They began with Computational Fluid Dynamics (we call it CFD) simulations to analyze thousands of rim shapes. Then they moved through wheel-only and full bike-plus-rider wind tunnel testing. The tests finished up outdoor sensor-based validation. Every stage is designed to ensure that aerodynamic gains translate into real-world speed. The goal? To get fast.
Rider-focused highlights
Front rim depth and patented Limitless Width Aero Technology keep airflow attached at high yaw angles for stable handling.
The rear wheel is shallower and narrower. It prioritizes power transfer and lightness.
Reduced spoke count, internal nipples, and 1.7g Vonoa Ti_UD carbon spokes cut rotational drag and sharpen responsiveness.
Wheels are optimized for 28–30mm tires.
Wind tunnel tests are showing 4.35 watts faster than ENVE 4.5 Pro, and outdoor tests showing up to 8.5 watts faster than Zipp 404 Firecrest.
Hunt’s design balances front-wheel aerodynamic efficiency with rear-wheel power transfer. Low-density polymer in the front rim sidewalls widens the shape without adding weight, improving airflow and stability, while the rear rim ensures efficient watt-to-road conversion.
They are built from a blend of T700, T800, and T1000 UD carbon fibres reinforced with Mitsubishi Pyrofil HR4012M, the 5AM Limitless wheels offer strength, durability, and low weight.
The CNC-machined 7075-T6 aluminium hubs deliver fast engagement, slim aerodynamics, and easy maintenance, while hybrid-ceramic bearings promise smooth, long-lasting rotation.
The 5AM Limitless wheels are available for pre-order now, shipping in May.
