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 | 1381G

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 tire compatibility.

SLC Hubs

All-new Sprint SLC hubs add strength and enhance power transfer, meaning more of your power pushing you forwards. The hub shell is a cold-forged 7000 series alloy, offering a greater strength-to-weight ratio than extruded 6000 series alloys. Large 15mm diameter hub axles for sprinting and out-of-saddle climbing responsiveness. Circular dropout interface steps ensure a secure fitment.

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 tire, or that you can't easily maintain.

Please include the weight of any luggage in your total rider weight when choosing the correct wheels. If a rider is over 178lbs then an experienced bike mechanic should check the wheel regularly and it is advisable to use tires at max 90psi as this will reduce the fatigue on the wheelset. We are cyclists ourselves and do of course go above and beyond to offer excellent service if you ever do experience any issues. We carry full spares at very reasonable prices and offer complete support.

    60 Day Ride & Return Period. We are certain you'll be impressed by the acceleration, low-weight, speed and durability of our wheels. We are cyclists and as such strive to offer class leading service and support.

    Tubeless Tire Options

    We can supply tubeless tires (including sealant) with your wheels, they are also designed to work excellently with clincher tires and tubes.

    Maximum tire pressure for this rim is 100psi when used with 25-28mm tires. Maximum tire pressures for other tire sizes: 30mm - 32mm do not exceed 70psi, 33mm do not exceed 50psi, 35-45mm do not exceed 45psi, 45-50mm do not exceed 40psi. 100psi is more than enough for any rider on road.

    Schwalbe Pro One Tubeless Tyres

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

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

    Schwalbe G One Tubeless Tyres

    Schwalbe G One Speed Tubeless Tires - 30mm

    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 tire 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.
