HUNT 40 LIMITLESS GRAVEL AERO UD CARBON SPOKE WHEELSET
AERODYNAMICALLY OPTIMISED FOR MAXIMUM SPEED & CROSSWIND STABILITY
40/41 DEEP | 36/35 WIDE EXT | 27/26 WIDE INT | 1,328G I STAINLESS BEARING or CERAMICSPEED I H_RATCHET 48T DBL
THE PURPOSE
Engineered to maximize aerodynamic advantage for today's high-speed gravel races, without compromising on weight, responsiveness or crosswind stability. With the sharp end of today's gravel races mirroring the speed and tactics of road racing, our athletes asked us for wheels that held speed for solo moves and offered the quick acceleration they need to close gaps and attack on climbs. Aerodynamically optimized around 40 and 45mm Schwalbe G-One gravel tyres to reduce aerodynamic drag across the system, saving you watts and time. Wind tunnel-proven crosswind stability allows you to focus on your race, regardless of the wind conditions, while the extra-wide rim beads prevent race-ending pinch flats.
WIND TUNNEL PROVEN TECHNOLOGY
Through the use of the entire engineering suite, HUNT’s in-house engineering team has spent the last two years developing the rim profiles for the 40 Limitless Gravel Aero to maintain the aero efficiency benefits achieved by the category-leading Hunt 42 LGA wheels, while significantly reducing system weight and optimizing rim shapes around wider modern gravel tyres. The wind tunnel results, as seen in the graph, depict the performance of HUNT 40 Limitless Gravel Aero wheels among a range of world class aero wheels commonly used in competitive gravel racing. The data suggests that with both a 40mm and 45mm tyre, the HUNT 40 Limitless Gravel Aero has the second-best aerodynamic drag while offering the fastest overall package when considering aerodynamic drag and system weight. With the use of patented Limitless Width Aero construction and UD Carbon Spokes, HUNT was able to design unique front and rear rim profiles that offers an extremely wide profile with a truncated edge (blunted spoke bed) to help airflow remain attached to the system, while providing weight saving of up to 220g compared to the 42 Limitless Gravel Aero, and enhanced performance and durability on the harshest gravel roads due to the addition of wider internal rim widths and rim walls to prevent pinch flats.
FEATURES
- Rims | Front and rear specific rim profile. The wider front rim profile (36mm wide ext/27mm wide int) provides an optimized aero interface at the leading edge of the bike, reducing drag and offering predictable handling in crosswinds. The increased internal rim width on the front design provides improved traction and cornering performance due to the more open tyre profile. The rear of the bike encounters more turbulent air flow, allowing for the engineering team to optimize the rear rim profile (35mm wide ext/26mm wide int) for power delivery and weight savings. HUNT-patented Limitless Width Aero manufacturing process allows for a wider external rim shape while minimizing material mass, utilizing a strip of low-density structural polymer inserted in a molded channel within the rim sidewall with carbon molded over it. The wider shape and the more blunted the spoke bed increases aerodynamic performance across a wider range of yaw angles (as the airflow is predictable and does not separate to the same degree), resulting in fast, ultra-stable rim shapes without the weight penalty.
- Wind Tunnel Tested I Aerodynamically optimised for 40 and 45c tyres. The rounded U-shaped hookless rim profile reduces aero-dynamic drag across yaw angles. HUNT’s in-house engineering team, leveraging CFD analysis and 3D prototyping, along with the proven validation method of wind tunnel testing, has raised the expectation level for aerodynamic efficiency while simultaneously reducing the wheel system weight and increasing responsiveness, creating a world-beating combination of performance attributes.
- Durability I The in-house engineering team have designed and tested against new gravel wheel protocols which far exceed industry-standard ISO testing. Combining this with a broad 4.5mm bead hook thickness reduces the likelihood of pinch flats while maximizing your comfort and rolling resistance when running low tyre pressures.
- Hubs | The new dual-sided ratchet system with 48-tooth drive delivers a fast 7.5 degrees of engagement. 6061 aluminium alloy hub shell with extra strong 7075-T6 alloy axle. Featuring HUNT’s H_Ratchet double-sided system (with two floating ratchet rings), with a 48t ratchet ring resulting in just 7.5˚ engagement. Durability is a theme for HUNT, and so all our freehub bodies have a H_CERAMIK coating, a process similar to anodization to increase its density and hardness of the surface laser to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.
- UD Carbon Spoke I TaperLock UD carbon spokes offer up to a 6% increase in lateral responsiveness against steel equivalents. Only 2.7g per spoke and yet can handle tightening forces of ~450kgf per spoke compared to around 290kgf for leading stainless steel aero spokes.
- Tires | Designed around a 25mm internal rim width optimised aerodynamically for 38-42c gravel tires, these will work with any tire up to 54c. Fully ETRTO-compliant and tubeless-ready. Work excellently with both clincher and tubeless-ready tires.
- Elliptical Wing Spokes | Pillar Wing 20 Elliptical Aero stainless steel spokes offer excellent performance-to-weight, and significant aero gains over round spokes. The patented design resists twisting under tension. Black anodized finish.
- Tyre Width Optimization I Designed with 27/26mm internal rim width optimised for 40mm and 45mm tyres. ETRTO-compatible for tyre sizes 35mm and 60mm and tubeless-ready.
- Bearings I Double sealed stainless steel cartridge bearings offer smooth, reliable service with low friction.
- Axles | Easily adaptable & we fit them for you. Fit all current axle sizes and are easy to change; Front - QR, Bolt thru 12/9mm, Rear - QR, Bolt thru 12x142, 12x135, 10x135.
- Included | Tubeless tape & valves, spare spokes, axle adapters (please fill in the simple form after checkout to select your required size).
- Weight | 1,328g
- Max Rider Weight I 130kg including luggage, If you are above 105kg, check the wheels regularly with professional mechanics.
- H_CARE lifetime crash replacement included for first owners
IN THE BOX
- HUNT Black Shield tubeless tape fitted to wheels.
- The axle adapters needed for your bike, just fill in the simple form shown after order completion, the form is also included in your order confirmation page.
- Cassette spacer for 8/9/10 speed
- Tubeless Valves (60mm)
- Quality control card signed by your wheel builder
