HUNT 4454 UD Carbon Spoke Disc Wheelset
HUNT 4454 UD Carbon Spoke Disc Wheelset
HUNT 4454 UD Carbon Spoke Disc Wheelset
<h1>Aerodynamicist Rim Profile</h1><i>As learned from our Limitless Research project & consistent wind tunnel time across the past 2 years, we know that an optimum aerodynamic benefit for a drop-bar bike is yielded from widening rim profiles. The reasons for this is that it allows for a far more 'blunted' spoke bed area, which (depending on which part of the wheel you're looking at) is both the leading and trailing edge.</i>
<h1>Aerodynamicist Rim Profile</h1><i>The benefits of blunted spoke bed areas revolve primarily around the predictable airflow, with the wind ‘hugging’ the rim as it passes across it (as opposed to older style V-shaped rims, which would create turbulence in the form of stalls). The wider profile ensures the flow stays attached to the surface as long as possible before the point of separation, which is key as yaw angles increase..</i>
<h1>TaperLock Hubs</h1><i>Carbon spoke optimised TaperLock SPRINT hubs add strength and enhance power transfer meaning all your force pushes you forwards. Large 15mm diameter hub axles for sprinting and out-of-saddle climbing responsiveness. Circular dropout interface steps add extra stiffness.</i>
<h1>Freehub Body</h1><i>Featuring a 3 multi-point pawls with 3 teeth each and a 48 tooth ratchet ring results in an impressively low 7.5 degree engagement angle and excellent resistance to wear under heavy loads. The Sprint freehub has strong individual pawl springs which engage quicker. There is also a Steel Spline Insert re-enforcement to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.</i>
<h1>Tyre Width Optimisation</h1><i> Designed around a 20mm internal rim width optimised for a 25c tyre (but will of course work without compromise with both 23c and 28c tyres). Naturally, as with all of our rims, they feature a hooked tyre retention design for safety, and are both fully ETRTO-compatible and tubeless-ready.</i>
<h1>Rim Bed</h1><i>H-Lock is our tubeless-ready rim bed profile with up-kicks to the shoulders of the tubeless steps which help to create a great rim-well seal for first installation and easy sealing of tubeless tyres. The H-Lock profile also locks the beads in place more securely once seated. This is especially important when running lower pressures off road.</i>
<h1>UD Carbon Spokes</h1><i>Incredibly strong (achieving over 450kgf per spoke) TaperLock UD carbon spokes offering 30% increase in stiffness against steel ones. Only 2.7g per spoke. Due to the TaperLock technology, these spokes can be trued easily using a spoke key from within the rim bed.</i>
<h1>Comfort</h1><i>As well as carbon fibre composites being lighter and stiffer than steel, the inherent energy dissipation qualities seen in carbon fibre composites can play a significant role in “road buzz” absorption. Coupled with the reduced number of spokes required to achieve this stiffness, the ride quality and feedback can be greatly improved.</i>
<h1>Stiffness-to-Weight</h1><i>With significant increases in lateral stiffness, they have been engineered to provide a stiffness-to-weight ratio previously unseen on serviceable wheels. Coming in at just 1427g but with significant increases in lateral responsiveness, disc wheels have never been so fast.</i>
<h1>Tyres</h1><i>At HUNT we enjoy the puncture resistance and grip benefits of tubeless on our every-day rides so we wanted to allow you the same option, but of course these tubeless-ready wheels are also designed to work perfectly inner tubes, just use tubes in tubeless ready tyres.</i>
<h1>Adaptability</h1><i>Our wheels are seriously future-proof. We can adapt your wheels to any current axle standard, you just need to let us know what you require by filling in the simple form on the confirmation page after checkout. Please note these wheels will not work with the older 15mm front road TA standard. As Shimano hydraulic brakes are appearing on many new bikes, we wanted riders to have the option so we went even more adaptable with centre-lock hubs and 6 bolt adaptors included.</i>

HUNT 4454 UD Carbon Spoke Disc Wheelset

44/54 Deep | 29 Wide | 1427g

THE SUPREME STIFFNESS-TO-WEIGHT RATIO OF CARBON SPOKES, IN A SERVICEABLE PACKAGE. THE FINAL WORD IN ROAD/ALL-ROAD DISC-BRAKE PERFORMANCE.

44/54 DEEP | 29 WIDE EXT | 20 WIDE INT | 1427g

The Purpose

Introducing the 4454 UD Carbon Spoke Disc, utilising our proven TaperLock carbon spoke technology, resulting in fully serviceable carbon-spoked wheels that can be trued like any other. With significant increases in lateral stiffness (see testing info below), they have been engineered to provide a stiffness-to-weight ratio previously unseen on serviceable wheels.

HUNT TaperLock UD Carbon Spoke Logo

6% more laterally responsive than identical steel spoked wheel, with significantly less weight. Further benefiting from the high-frequency vibration absorption capabilities of carbon fibre in the UD spokes, as well as the rim. Please see graph in the "read more" section below.

aerodynamicist_profile

Aerodynamicist 29mm-wide rim, exclusively engineered and wind tunnel tested by Luisa Grappone, HUNT Engineering Manager, featuring a hooked & ETRTO-compliant tubeless-ready rim, designed for full clincher & tubeless tyre compatibility.

H_CARE Logo

As most of you will already know, we design our wheels to take a pretty impressive amount of hammering under all sorts of conditions. Whether you're hitting out at your local crit or road race, or taking the long way home on the paths less travelled, you can do so with the confidence that you're rolling on hoops designed to take the lot in their stride.

Accordingly, we now offer free lifetime crashreplacement for the first owners of these wheels.

Using an innovative spoke-seating method, the 4454 UD Carbon Spoke Disc wheelset offers carbon spokes that are held purely mechanically, with no bonding required. We call this TaperLock, and it allows for carbon spokes that can be trued and maintained just like a normal steel spoke.

The TaperLock UD Carbon Spokes are incredibly strong, achieving over 450 kgf (kilograms force per spoke) maximum tensile strength, compared to leading steel spokes which conventionally reach around 300 kgf.

For HUNT, aerodynamics and stiffness have to be considered as component parts of a more holistic understanding of performance componentry. That's why we always design with serviceability and usability in mind, because there's no point having a fast wheel you can't use with your favourite tyre, or that you can't easily maintain.

    Schwalbe Pro One Tubeless Tyres

    Schwalbe Pro One Tubeless Tyres - 23, 25 or 28mm

    The Schwalbe Tubeless road tyres consistently win plaudits from journalists and customers alike. We have been testing them for a long time and have been very impressed.

    Unleashing profile and breathtakingly fast - especially when large volume counts. As a 30mm wide road race version with V-Guard, G-One Speed is a tyre for the real tough jobs. You can ride it as a handmade tubular or with the most modern tubeless easy technology. But it is also a guarantee for maximum speed in the extra-wide 60mm execution - of course, not only at the fascinating beach races on Holland’s coasts. The new G-One Speed is an evolution of the former S-One and Big One.
