<h1>Aerodynamicist Rim Profile</h1><i>Our Limitless research and extensive wind tunnel tests found that wider rim profiles yield optimal aerodynamic benefits for riders. The more 'blunted' spoke bed area creates predictable airflow at a wider variety of wind yaw angles, with the air ‘hugging’ the rim as it passes across it, staying attached to the surface as long as possible before the point of separation. Traditional V-shaped rims tend to create turbulence in the form of stalls.</i>
<h1>CeramicSpeed</h1><i>CeramicSpeed's world-renowned, low-friction bearings. With CeramicSpeed bearings in your hubs, tests show that you will save between 6–9 watts, compared to using standard bearings. As chosen by top athletes and teams around the world. </i>
<h1>Sprint SL hubs</h1><i>All-new Sprint SL hubs featuring the same reliable engagement at a lower weight package. The hub shell is 6066 series alloy, offering a greater strength-to-weight ratio than lower 6000 series alloys. Large 15mm diameter hub axles for climbing and out-of-saddle sprinting responsiveness. Circular dropout interface steps ensure a secure fitment. </i>
<h1>Freehub Body</h1><i>Featuring 3x treble-tooth pawls 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 drive a consistent engagement. There is also a Steel Spline Insert re-enforcement on Shimano cassettes to provide excellent durability against cassette sprocket damage. </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>Tyre Width Optimisation</h1><i>Designed around a 20mm internal rim width optimised for a 25-28c tyre. They feature a hooked rim design and are both fully ETRTO-compatible and tubeless-ready. </i>
<h1>Adaptability</h1><i>Our wheels are futureproof. 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>

The Purpose

For riders competing in disciplines where absolute aerodynamic efficiency is critical, the engineering team at HUNT Bike Wheels saw the potential for wider, front and rear-specific rim profiles to provide considerable time savings while offering improved stability in crosswinds. Stability and predictable handling characteristics allow the rider to maintain a low, aerodynamic position on the bike despite changing wind conditions. Read More

Driven by in-house Computational Fluid Dynamics (CFD) analysis and extensive wind tunnel testing, HUNT has expanded the Aerodynamicist collection to include two deep-section carbon wheelsets to meet the needs of triathlon, time trial and criterium riders. The design approach addressed the differing aerodynamic demands of front and rear wheels as part of the whole system to deliver maximum confidence in handling and exceptional speed. The three resulting wheel designs include two front wheel options with depths of 73mm and 83mm, both paired with an 87mm-deep rear wheel, offering riders the choice between two distinctly different wheelset systems depending on their conditions, preferences, and goals.

Both wheelset offerings provide world-class aerodynamic performance for the rider against the tested competitors whilst delivering stable and predictable handling characteristics. Laced to our new, lighter Sprint SL hubs offering rapid 7.5-degree engagement, these wheelsets are built for race day. HUNT has published a full research white paper summarizing the results of the two-year-long design, development, prototyping, testing and validation process. Read Less

INTRODUCTION AND PROCESS

HUNT set out to create two wheelset systems for riders seeking the utmost in aerodynamics for time trial, triathlon and criterium racing, each set with a different front wheel depth, allowing riders to choose the best option for their riding. After two years of CFD modeling, prototyping, wind tunnel testing, and rider testing, HUNT created an 87mm deep rear rim profile maximized for the aerodynamic demands at the rear of the bike and designed to provide optimal lateral responsiveness and efficient power transfer. The two front wheel options offer riders category-leading aerodynamics and crosswind stability at different depths (73mm and 83mm depth), depending on their riding conditions, preferences, and goals.

Read More

The widespread adoption of disc brakes in all formats of modern racing has offered the opportunity to transform rim profile development without the dimensional constraints of rim brake calipers, allowing for wider, aerodynamically optimized rims shapes. On top of the aerodynamic possibilities, riders also benefit from wider tyres and lower pressures, known to reduce rolling resistance and road vibration while improving grip. Time trials, triathlons, and criteriums are specific disciplines in which the high average speeds and typically flat courses offer the opportunity to generate significant aerodynamic benefits for the rider through deep rim profiles. However, the high speeds and common crosswinds require those deep wheels to be stable and predictable, so that the rider can maintain a low, aerodynamic position on the bike regardless of conditions. These demands (fast and stable) are both met through wider profiles.

CFD PROCESS

In recent years, HUNT has invested in developing its Research and Development capabilities to deliver science and engineering-led, high-performance wheels to their riders. One key focus has been to build in-house expertise in using Computational Fluid Dynamics (CFD) modelling techniques in the aerodynamic design of performance bicycle wheels.

CFD is the analysis of fluid flow around an object using numerical methods and a computational model to replicate the desired conditions, such as a bicycle wheel in a wind tunnel, and assess the aerodynamic performance. It is a development tool that accelerates the engineering process and allows us to explore new ideas and iterations at a rapid pace, but it is not a replacement for wind tunnel testing, which combined with real-world rider testing, provides the final validation of product performance. Traditionally, aerodynamic profile development has been conducted in the Wind Tunnel, which involves manufacturing several prototypes to test theories and profiles. This often means executing a wind tunnel test session without clear prediction of the outcomes, which can then necessitate the time and investment-intensive process of repeated prototyping and testing to identify the optimal solution.

PROFILE DEVELOPMENTS

The HUNT engineering team selected a depth of 73mm for shallowest front rim profile, chosen to minimize the effects of side forces from crosswinds whilst maximizing aerodynamic efficiency in a straight line. The validated wind tunnel performance of the 60 Limitless Aero Disc served as the benchmark and starting point for the 73mm profile. Feedback from HUNT-supported WorldTour riders (2021 Team Qhubeka Assos) suggested that the extra wide rim profile of the 60 Limitless Aero Disc resulted in an ultra-fast wheelset that handled cross winds and side forces like a much shallower wheel, an attribute that would be extremely valuable in an even deeper format.

WHY WE CREATED FRONT AND REAR SPECIFIC RIM SHAPES:

Due to the generally laminar (constantly attached) nature of airflow, an object immediately behind another object will be subjected to disordered airflow of different speeds and directions, and therefore must be designed to reduce drag in those disordered airflow conditions. Applying this to cycling, and in particular, wheels, front and rear wheels encounter different airflow conditions and therefore have unique aerodynamic roles to play in the system. The HUNT engineering team has purposefully designed the front and rear rims in this system for their specific role, creating an optimal combination of drag reduction, crosswind stability, and low weight.

As shown in the graphs, the HUNT 7387 Aerodynamicist Aerodynamicist Carbon Disc wheelset produces exceptionally low drag values when compared to numerous leading relevant competitors with both 25mm and 28mm tyres (see white paper for full tested competitive set). The DT Swiss Dicut 80F / 80R produced the lowest aerodynamic drag from the competitor tested and became the benchmark competitor for further testing.

The HUNT 7387 Aerodynamicist Carbon Disc wheelset, our shallower front wheel offering, was designed to maximize aerodynamic benefit with minimal steering moment magnitude. The final tests concluded that the HUNT 7387 Aerodynamicist Carbon Disc wheelset provides very low steering moment given its depth, easily outperforming most industry leading competitors in both stability and minimising aerodynamic drag, performing only 0.35W slower than the deeper 8387 offering in the same conditions whilst minimising steering forces.

The HUNT 7387 Aerodynamicist delivered results within 0.52W of highest performing DT Swiss Dicut 80mm, when paired with both 25 and 28mm tyres.

    The Purpose

    For riders competing in disciplines where absolute aerodynamic efficiency is critical, the engineering team at HUNT Bike Wheels saw the potential for wider, front and rear-specific rim profiles to provide considerable time savings while offering improved stability in crosswinds. Stability and predictable handling characteristics allow the rider to maintain a low, aerodynamic position on the bike despite changing wind conditions. Read More

    Driven by in-house Computational Fluid Dynamics (CFD) analysis and extensive wind tunnel testing, HUNT has expanded the Aerodynamicist collection to include two deep-section carbon wheelsets to meet the needs of triathlon, time trial and criterium riders. The design approach addressed the differing aerodynamic demands of front and rear wheels as part of the whole system to deliver maximum confidence in handling and exceptional speed. The three resulting wheel designs include two front wheel options with depths of 73mm and 83mm, both paired with an 87mm-deep rear wheel, offering riders the choice between two distinctly different wheelset systems depending on their conditions, preferences, and goals.

    Both wheelset offerings provide world-class aerodynamic performance for the rider against the tested competitors whilst delivering stable and predictable handling characteristics. Laced to our new, lighter Sprint SL hubs offering rapid 7.5-degree engagement, these wheelsets are built for race day. HUNT has published a full research white paper summarizing the results of the two-year-long design, development, prototyping, testing and validation process. Read Less

    INTRODUCTION AND PROCESS

    HUNT set out to create two wheelset systems for riders seeking the utmost in aerodynamics for time trial, triathlon and criterium racing, each set with a different front wheel depth, allowing riders to choose the best option for their riding. After two years of CFD modeling, prototyping, wind tunnel testing, and rider testing, HUNT created an 87mm deep rear rim profile maximized for the aerodynamic demands at the rear of the bike and designed to provide optimal lateral responsiveness and efficient power transfer. The two front wheel options offer riders category-leading aerodynamics and crosswind stability at different depths (73mm and 83mm depth), depending on their riding conditions, preferences, and goals.

    The widespread adoption of disc brakes in all formats of modern racing has offered the opportunity to transform rim profile development without the dimensional constraints of rim brake calipers, allowing for wider, aerodynamically optimized rims shapes. On top of the aerodynamic possibilities, riders also benefit from wider tyres and lower pressures, known to reduce rolling resistance and road vibration while improving grip. Time trials, triathlons, and criteriums are specific disciplines in which the high average speeds and typically flat courses offer the opportunity to generate significant aerodynamic benefits for the rider through deep rim profiles. However, the high speeds and common crosswinds require those deep wheels to be stable and predictable, so that the rider can maintain a low, aerodynamic position on the bike regardless of conditions. These demands (fast and stable) are both met through wider profiles.

    CFD PROCESS

    In recent years, HUNT has invested in developing its Research and Development capabilities to deliver science and engineering-led, high-performance wheels to their riders. One key focus has been to build in-house expertise in using Computational Fluid Dynamics (CFD) modelling techniques in the aerodynamic design of performance bicycle wheels.

    CFD is the analysis of fluid flow around an object using numerical methods and a computational model to replicate the desired conditions, such as a bicycle wheel in a wind tunnel, and assess the aerodynamic performance. It is a development tool that accelerates the engineering process and allows us to explore new ideas and iterations at a rapid pace, but it is not a replacement for wind tunnel testing, which combined with real-world rider testing, provides the final validation of product performance. Traditionally, aerodynamic profile development has been conducted in the Wind Tunnel, which involves manufacturing several prototypes to test theories and profiles. This often means executing a wind tunnel test session without clear prediction of the outcomes, which can then necessitate the time and investment-intensive process of repeated prototyping and testing to identify the optimal solution.

    PROFILE DEVELOPMENTS

    The HUNT engineering team selected a depth of 73mm for shallowest front rim profile, chosen to minimize the effects of side forces from crosswinds whilst maximizing aerodynamic efficiency in a straight line. The validated wind tunnel performance of the 60 Limitless Aero Disc served as the benchmark and starting point for the 73mm profile. Feedback from HUNT-supported WorldTour riders (2021 Team Qhubeka Assos) suggested that the extra wide rim profile of the 60 Limitless Aero Disc resulted in an ultra-fast wheelset that handled cross winds and side forces like a much shallower wheel, an attribute that would be extremely valuable in an even deeper format.

    WHY WE CREATED FRONT AND REAR SPECIFIC RIM SHAPES:

    Due to the generally laminar (constantly attached) nature of airflow, an object immediately behind another object will be subjected to disordered airflow of different speeds and directions, and therefore must be designed to reduce drag in those disordered airflow conditions. Applying this to cycling, and in particular, wheels, front and rear wheels encounter different airflow conditions and therefore have unique aerodynamic roles to play in the system. The HUNT engineering team has purposefully designed the front and rear rims in this system for their specific role, creating an optimal combination of drag reduction, crosswind stability, and low weight.

    THE RESULTS

    As shown in the graphs, the HUNT 7387 Aerodynamicist Aerodynamicist Carbon Disc wheelset produces exceptionally low drag values when compared to numerous leading relevant competitors with both 25mm and 28mm tyres (see white paper for full tested competitive set). The DT Swiss Dicut 80F / 80R produced the lowest aerodynamic drag from the competitor tested and became the benchmark competitor for further testing.

    The HUNT 7387 Aerodynamicist Carbon Disc wheelset, our shallower front wheel offering, was designed to maximize aerodynamic benefit with minimal steering moment magnitude. The final tests concluded that the HUNT 7387 Aerodynamicist Carbon Disc wheelset provides very low steering moment given its depth, easily outperforming most industry leading competitors in both stability and minimising aerodynamic drag, performing only 0.35W slower than the deeper 8387 offering in the same conditions whilst minimising steering forces.
