HUNT SUB50 Limitless UD Carbon Spoke Disc Wheelset

1380g	Depth	Width ext	Width int	size
1380g	49.5 mm	F34 / R30 mm	23 mm	700c

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 optimising for modern width road tyres (28mm and 30mm) and achieving the lowest system weight possible.

Aero optimised for 28mm and 30mm tyres; works well with 28mm up to 45mm.

"While it’s difficult to quantify a wheel’s aerodynamics accurately, I’ve ridden enough wheels to know when one feels fast—the SUB50 does. And perhaps more importantly, the SUB50 feels incredibly sure-footed at speed."

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 tyres (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 tyre 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.

KEY FEATURES_

Limitless 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.

Front & Rear Specific Rim Design

Through the extensive testing with CFD modeling and Wind Tunnel validation, our engineering team havedeveloped front and rear specific profiles (34.2mm wide by 49.5mm deep front, 30mm wide by 49.5mm deep rear) that maximize aero benefit while minimizing material mass. Wide where it matters, fast everywhere.

H_Ratchet DBL HUBS

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.

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 fit for the HUNT H_Ratchet hubset at the CeramicSpeed factory, with extreme tolerances measured within a thousandth of a millimeter.

Wind Tunnel Tested

Developed by HUNT’s in-house engineering team, leveraging CFD analysis and 3D prototyping, along with the proven validation method of wind tunnel testing, the HUNT engineering team 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.

UD Carbon 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.

Tyres Info

HUNT recommends a 28-30mm tyre for best performance, tyre widths between 28mm and 47mm are also safe to use. You must not exceed the maximum tyre pressure limits set out in the table below or the maximum limit set by your tyre manufacturer if this is lower. Only use tyres marked as compatible with hookless (TSS) rims. Note: best performance is usually gained by using tyre pressures lower than the maximum, you can see our blog post here about this. Tubeless-ready for lower weight and rolling resistance.

Bike Magazine and Websites Expert's Views

"While it’s difficult to quantify a wheel’s aerodynamics accurately, I’ve ridden enough wheels to know when one feels fast—the SUB50 does. And perhaps more importantly, the SUB50 feels incredibly sure-footed at speed."

"Acceleration and handling as well as stability are impressive. In addition, the SUB50 Limitless were very predictable and not very nervous on fast descents. And that is anything but a given for wheels with this rim depth. Overall, a great package at a reasonable price."

“These are premium wheels with technology to command a price point that matches. It's worth remembering though, Hunt is actually offering features that are one more level up.”

WARRANTY_

These wheels come with H_CARE (Free Lifetime Crash Replacement) for the first owners. Read all about it here.

A full 3 years (4 years on CeramicSpeed bearings*) from purchase date warranty is offered to the original purchaser only on all HUNT wheels against material or workmanship defects, please click here to read full details.

Stated wheel weights: Our stated wheel weights reflect the wheelset only; without rim tape, tubeless valves or disc brake lock rings, as is industry standard. A 3% variance (lower or higher) in total system weight is normal for wheelset manufacturing.

All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. Max system weight 125 kg (system weight total weight of fully kitted up rider, bike and luggage). If the system is over 105 kg then an experienced bike mechanic should check the wheel regularly.
