THE PURPOSE
 
The in-house engineering team at HUNT aimed to create the absolute fastest, no compromise, all-around road race wheelset up to and including 50mm in depth, while optimizing for modern width road tires (28mm and 30mm) and achieving the lowest system weight possible. The SUB50 Limitless takes what we learned from creating our disc-brake wheelset redefining 48 Limitless (34.5mm wide), which when launched in 2019 proved in the wind-tunnel to be the fastest in its category. From that industry leading change others have followed. A further three-year engineering development process has elevated the performance again with the SUB50 Limitless. Offering riders wind tunnel proven best-in-class aerodynamic efficiency and stability, combined with tire shape optimization, at an impressively low system weight of 1380 grams, the SUB50 Limitless once more sets the standard for all-round road racing wheels.
 
Front and rear specific rim shapes maximize aero benefit at the front of the bike while reducing mass at the rear, leveraging the latest advancements in composite layup capabilities to create featherweight profiles that meet the extreme structural and durability demands of modern racing and riding.
 
Further weight savings and responsiveness gains were achieved leveraging HUNT TaperLock UD Carbon Spoke technology, with over four seasons of proven race performance in the pro ranks. The new H_Ratchet dual-sided 40T ratchet hub system offers reliable 9-degree engagement with less material, weighing just 332 grams per pair.
 
Validated in the wind tunnel, the SUB50 Limitless aerodynamically outperforms relevant competitor wheels up to and including 50mm in depth with modern 30mm wide tires, offering a 1.8-watt advantage over the next fastest competitor. The SUB50 further outperforms the competitive set when aero efficiency-to-weight and aero efficiency-to-depth metrics are taken into account. Utilizing Limitless Width Aero Technology, the SUB50 offers smooth steering moment values across a wide range of yaw angles, resulting in stable and predictable ride characteristics.
The result is a profoundly versatile all-around aero wheelset. More speed, less weight. Wide where it matters, faster everywhere.
 
Includes FREE H_Care lifetime crash replacement for the first owners of these wheels. 
 
KEY FEATURES
 
FRONT AND REAR-SPECIFIC HOOKLESS RIM PROFILES (34.2MM WIDE EXTERNAL FRONT, 30MM WIDE EXTERNAL REAR), UD CARBON SPOKES, AND RATCHET HUB DESIGN CREATE AN UNMATCHED SYSTEM WEIGHING JUST 1380 GRAMS PER PAIR.
 
Limitless Width Aero Technology | HUNT-patented manufacturing process which utilizes a strip of low-density structural polymer inserted in a molded channel within the rim sidewall with carbon molded over it, allowing for extra width while minimizing material mass.
Rims | 34.2mm-wide front rim profile maximizes aero benefit at the front of the bike where it encounters clean, undisturbed airflow. 30mm-wide Rear rim profile reduces weight without significantly negatively impacting whole system aerodynamics.
Tires | 23mm rim bed optimised for superior aerodynamic performance with a 28-30c tubeless tire. ETRTO compliant with tubeless, hookless/TSS-ready tires size 28c through 58c. Please note, clincher tires must not be used on hookless rims. Always consult the tire manufacturer’s guidance for compatibility with hookless rims.
Hubs | H_Ratchet DBL - Dual-sided ratchet system with 40-tooth drive rings offering 9-degree engagement and 332g weight per set. 6066 aluminum alloy hub shell with extra strong 7075-T6 alloy axle and freehub body. H_Ceramik reinforced coating to protect against gouging. Please note: If you require a 6 bolt adaptor you can purchase separately here
CeramicSpeed Bearings | The pro teams’ choice and the undisputed leader in low rolling resistance and high durability. One size does not fit all. CeramicSpeed bearings are custom fitted for the HUNT H_Ratchet hubset at the CeramicSpeed factory, with extreme tolerances measured within a thousandth of a millimeter.
Spokes | TaperLock UD carbon spokes offer up to a 30% increase in lateral responsiveness against steel equivalents. Only 2.7g per spoke and yet can handle tightening forces of ~450kgf per spoke. Spoke count: 18 Front, 20 Rear.
Axles | Easily adaptable & we fit them for you. Fit all current axle sizes and are easy to change. Click here to see all axle sizes.
Hand-built | All of our wheels are built and finished by hand, inclusive of a full quality control inspection.
Included | Tubeless tape & valves, axle adapters (please fill in the simple form after checkout to select your required size).
Weight | 1380g
