Hunt has announced its latest flagship aero gravel wheels, the 5AM Gravel Limitless, claiming theyre lighter and more aerodynamic than almost anything else available.As with the British brands 5AM Limitless road wheels, which launched earlier this year, the 5AM Gravel Limitless wheels use an aero mullet rim pairing.This sees a deeper, wider front rim paired with a shallower and narrower rear rim, designed to offer the best balance of aerodynamic performance and low weight (a design pioneered by Specialized and its Roval Rapide CLX III wheels).Thanks to the use of the brand's patented Limitless technology, Hunt has pushed this to the extreme with an enormous 45mm external width on the front rim, while maintaining a 27mm internal width for improved tyre compatibility.Available now with steel or ceramic bearings, the Hunt 5AM Gravel Limitless wheels cost 1,999 / $2,399 / 2,399 with steel spokes, or from 2,449 / $2,899 / 2,899 with carbon spokes.Wide and light Hunt's latest gravel race wheels are mid-depth, super-wide and very light. Simon von Bromley / BikeRadar 2026 has seen gravel racing finally go aero en masse. There seem to be two distinct approaches to the problem of gravel performance forming, though.Many brands, for example, have gone all-in on low drag. Weve seen new hyper-aero gravel bikes, such as the Argon 18 Anti Matter, Ridley Kanzo Fast 2.0 and Factor Elara, taking gravel racing by storm, alongside ultra-deep gravel wheelsets such as the Newmen Streem G.62s, ENVE G SES 6.7 Pros and Black Inc Sixty Fours.The Hunt 5AM Gravel Limitless wheels, however, take a more balanced approach, prioritising both aerodynamic efficiency and low weight, rather than low drag above all else. Hunt specs its own alloy hubs, but you can choose between steel and carbon spokes. Simon von Bromley / BikeRadar In this respect, it's a wheelset more in line with Specializeds new Crux 5 gravel bike and its Roval Terra Aero CLX wheels, or Giants Revolt Advanced SL 0 and its carbon-spoked Cadex MAX GXR wheels.As for why Hunt chose this path, design engineer Patrick Brown told BikeRadar: For top level pros, that aero [performance] is really important, but for technical gravel where there are lots of accelerations weight and feel matters. The Ti_UD wheels (with carbon spokes) are competitiely light, at only 1,340g per set. Simon von Bromley / BikeRadar Well cover Hunts wind-tunnel testing results shortly, but the 5AM Gravel Limitless wheels tipped our the scales at impressively low figures only 1,340g for the carbon-spoked version and 1,480g with steel spokes (both with rim tape, but without valves).Specialized claims its Roval Terra Aero CLX wheels also weigh 1,340g, while Cadexs Max GXR wheels are claimed to weigh as little as 1,280g (without tape or valves).Both wheelsets are considerably more expensive, however, at 2,998 / $3,399.98 / 3,458 and 3,499 / $4,000 / 3,799, respectively. Opting for steel spokes sees the weight go up to 1,480g, but you save 450 / $500 / 500. Simon von Bromley / BikeRadar Despite this low weight, the Hunt rims are notably wide 54mm deep / 45mm wide up front, and 49mm deep / 38mm wide out back, both with 27mm internal widths.In comparison, the Roval rims are 50 / 45mm deep front and rear, and only 38.5mm wide, while the Cadex rims are 50mm deep and 35mm wide, front and rear.As with Hunts previous Limitless wheelsets, the 5AM Gravel Limitless rims are distinct in their super-wide rim beads, which are 9mm wide on the front rim and 5.5mm wide on the rear. The patented 'Limitless' ultra-wide rim beads are among the widest we've seen, at 5.5mm on the rear (left) and a whopping 9mm up front (right). Simon von Bromley / BikeRadar Hunt says this design helps strengthen the rims and reduces the chances of pinch flats, while the patented construction technology (which sees low-density polymer used in place of carbon fibre to reduce weight) helps reduce rim weight without sacrificing width.As is increasingly common on carbon gravel wheels, the rims are also hookless or Tubeless Straight Side (as opposed to hooked or Tubeless Crochet). The Limitless tech helps Hunt widen the rims without adding weight. Simon von Bromley / BikeRadar Hunt 5AM Gravel Limitless wind-tunnel resultsIn terms of that aerodynamic performance, Hunt says it can point to testing done at both the GST wind tunnel in Germany and at the Silverstone Sports Engineering Hub here in the UK.Hunt says it designed the 5AM Gravel Limitless wheelset around 50mm tyres, because thats what elite racers are using in the Lifetime Grand Prix (the US gravel scenes premier off-road bike racing series).After developing and testing prototypes in CFD (Computational Fluid Dynamics) and at the GST wind tunnel, Hunt says it tested the final wheelsets against a broad range of competitor options at the Silverstone wind tunnel using a Specialized Crux 5 as the test rig. Hunt selected a Specialized Crux 5 as its wind-tunnel testing rig. Hunt Hunt selected an average wind speed of 11.3kph, and a bike speed of 40kph, because thats slightly faster than the average speed of races such as the 2025 edition of Unbound Gravel 200 (which was won at an average speed of 37.8kph).With 50mm tyres (Vittorias T30 gravel tyres), Hunts results show the 5AM Gravel Limitless Ti_UD carbon-spoked wheels as the lowest-drag option (by only 0.21 watts compared to Reserves 48|53 GR wheels which it notes is within the margin of error for the tunnel), saving just over 13 watts compared to its 4 Season Gravel alloy wheelset.

Hunt says the new 5AM Gravel Limitless wheels are wind-tunnel and race-proven. Hunt
