HUNT 4454 Aerodynamicist Carbon 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>Sprint SL Hubs</h1><i>SPRINT SL 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 SL 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>Spokes</h1><i>We chose the top-of-the-range Pillar Spoke Re-enforcement PSR XTRA models. These butted blade aero spokes are lighter but also provide a greater degree of elasticity to maintain tensions longer and add fatigue resistance. PSR spokes feature the 2.2 width at the spoke head providing more material in this high stress area. The nipples come with a hex head so you can achieve precise tensioning. Combining these components well is key which is why all HUNT wheels are hand-built.</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>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. </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>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>Weight</h1><i>The consequence of the fanatical attention to detail is an outstandingly light 1495 gram wheelset weight. Gone are the days when having a disc-equipped road bike always resulted in a weight penalty. You can now float up the climbs, and then brake later than the others on the way back down!</i>

The Purpose _

<h1>Sprint SL Hubs</h1><i>SPRINT SL 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>

The Purpose _

The 4454 Aerodynamicist Carbon Disc benefits from the further trickle-down effect of HUNT's in-house engineering team's Aerodynamicist rim profiles, as first seen on the 48 Limitless Aero Disc. The rims used are the same as in the 44 & 54 UD Carbon Spoke Disc, but paired with conventional steel spokes.

KEY FEATURES_

Spokes

We chose the top-of-the-range Pillar Spoke Re-enforcement PSR XTRA models. These butted blade aero spokes are lighter but also provide a greater degree of elasticity to maintain tensions longer and add fatigue resistance

TECHNOLOGY _

Following the release of our UD Carbon Spoke Disc range, many of you were asking if we could offer the Aerodynamicist rims found in that range with conventional steel spokes for usability & ease of maintenance.

As with all wheels featuring an Aerodynamicist profile, we've performed wind tunnel testing on the wheels to bring you the information on not only how these stack up against competitor wheelsets, but also how they sit within our range.

Tires Info
HUNT recommends a 25-28mm tire for best performance, tire widths between 22mm and 47mm are also safe to use.   Note: best performance is usually gained by using tire pressures lower than the maximum, you can see our blog post about this, read here.  Tubeless-ready for lower weight and rolling resistance.  You must not exceed the maximum tire pressure limits set out in the table below or the maximum limit set by your tire manufacturer if this is lower.

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..

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 SL 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 tires. The H-Lock profile also locks the beads in place more securely once seated. This is especially important when running lower pressures off road.

WARRANTY_

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

A full 3 years 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 275 lb (system weight – total weight of fully kitted up rider, bike and luggage). If the system is over 233 lb 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.
