<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 Hubs</h1><i>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>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>

More details Right

Aerodynamic performance in a lightweight package. Accessible aero, trickled down from our Limitless wheels.

4454 DEEP | 29 WIDE EXT | 20 WIDE INT | 1495G

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.

Aerodynamicist Logo

Aerodynamicist 29mm-wide rim, exclusively engineered and wind tunnel tested by HUNT's in-house engineering team, featuring a hooked & ETRTO-compliant tubeless-ready rim, designed for full clincher & tubeless tire compatibility.

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.

    All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. 240lbs is the upper recommended rider weight limit for these wheels. Please include the weight of any luggage in your total rider weight when choosing the correct wheels. If a rider is over 200lbs 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. Buy with confidence, if for any reason you wish to return the wheels for a full refund of your order you can do so up to a full 60 days after you receive them whether they have been ridden or not.

    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.
