THE PURPOSE
Hunt 54 UD Carbon Spoke Disc Wheelset은 검증된 Hunt TaperLock carbon spoke technology을 적용하여 스틸 스포크 휠셋처럼 손쉽게 정비가 가능한 카본 스포크 휠셋이다(Carbon Spoke Tension 조정은 림테이프를 제거한 후 림 내부에 체결된 스포크 헤드를 육각 렌치로 돌려 조정). 측면 강성 (lateral stiffness)의 향상으로 스포크 교체가능한 휠셋에서는 볼 수 없었던 강성 대비 무게 비율을 실현한 휠셋이다.
SLC HUBS
완전히 새롭게 개발된 Sprint SLC 허브는 강성과 힘전달력을 강화하여 보다 직진성을 향상시켰으며 허브 쉘은 냉간단조기법으로 제조된 7000 시리즈 알루미늄 합금으로 제작되어 6000 시리즈 합금보다 뛰어난 무게대비 강성을 제공한다. 15mm 대구경 허브 액슬로 스프린팅이나 오르막 댄싱에 더 뛰어난 반응성을 제공한다. 원형의 드롭아웃 표면은 확실한 장착성을 제공한다.
현격하게 감소된 무게와 함께 스틸 스포크 휠셋보다 6% 측면 반응성(lateral responsiveness)이 향상되었으며 UD carbon spokes로 인하여 노면 진동 흡수력(vibration obsorbtion)이 향상되었다.
Hunt engineer manager인 Luisa Grappone에 의해 실시된 통풍실험을 거치며 개발된 Aerodynamicist 29mm-wide rim은 타이어 장착부위에 hook이 있는 형태를 가진 tubeless-ready rim으로 클린처와 튜브리스 타이어 모두 대응이 가능하다. 아래 풍동실험 결과 참조.

"What Hunt has created - an affordable, servicable, carbon spoke option - is a gamechanger."
THE PURPOSE
Introducing the 54 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.
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.
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.
FEATURES
AERODYNAMICIST RIM PROFILE: 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.
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.
TAPERLOCK HUBS: 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.
UD CARBON SPOKES: 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.
TIRE WIDTH OPTIMISATION: Designed around a 20mm internal rim width optimised for a 25c tire (but will of course work without compromise with both 23c and 28c tires). Naturally, as with all of our rims, they feature a hooked tire retention design for safety, and are both fully ETRTO-compatible and tubeless-ready.
FREEHUB BODY: 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.
RIM BED: 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.
COMFORT: 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.
STIFFNESS-TO-WEIGHT: 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 1398g but with significant increases in lateral responsiveness, disc wheels have never been so fast.
TUBELESS READY: 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 tires.
ADAPTABILITY: 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.
