HUNT 48 Limitless Aero Disc
HUNT 48 Limitless Aero Disc
HUNT 48 Limitless Aero Disc
<h1>Patented LIMITLESS Technology</h1><i>In order to create the most aerodynamic & stable shape for the tyre, a rim bed of 22.5mm is needed. With the tyre profile this creates, the ideal shape of the rim curves out to an external width of 35mm. To overcome the weight penalty associated with this, we use a (non-structural) low density expanding polymer insert, inside a channel carved out during pre-preg.</i>
<h1>Patented LIMITLESS Technology</h1><i>This is bonded to the carbon during the curing process, resulting in an exceptionally strong bond. The density of carbon is 1.6g per cubic centimetre, whereas the polymer insert weighs just 0.7g per cubic centimetre, resulting in a (rotational) mass loss of just over 50g per rim.  This patented technology enables us to consider the limits of material properties, and smash right past them.</i>
<h1>CeramicSpeed Bearings</h1><i>The 48 Limitless Aero Disc will come fully equipped with CeramicSpeed's industry-leading hybrid ceramic bearings, even in the freehub body. All CeramicSpeed Balls are of the highest quality Grade 3 Silicon Nitride, featuring the highest achievable surface finish and roundness. The quality of the balls is what determines the performance and lifetime of a bearing. The CeramicSpeed Balls feature unparalleled impact strength, smoothness, roundness and brittleness.</i>
<h1>Freehub Body</h1><i>Featuring 3 multi-point pawls with 3 teeth each and a 48t ratchet ring. The result an impressively low 7.5 deg engagement angle. Durability is a theme for HUNT, and so all our freehub bodies have Steel Spline Insert re-enforcements to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies. Includes 2 CeramicSpeed bearings in the body.</i>
<h1>Nipples</h1><i>Despite designing a wheelset with aerodynamic supremacy in mind, serviceability and usability has always been a core philosophy of how we put wheels together. External spoke nipples are absolutely the right choice with this in mind, especially when running tubeless tyres as you would have to remove the tubeless tape to access the nipples were they to be internal</i>
<h1>Wing Spokes</h1><i>After considerable testing across multiple spoke types (including analysis against competitor spokes), we found that the aerofoil profile of Pillar's Wing 20 spokes offer even further aerodynamic advantages over flat/bladed options.</i>
<h1>Rim Profile</h1><i>Patented LIMITLESS technology allows for a 22.5mm rim bed and a huge 34.5mm external rim width, meaning the rim sits far wider than the tyre for aerodynamic superiority.</i>
<h1>UCI Approved</h1>
<h1>Tyre Compatibility</h1><i>Optimised aerodynamically for a Schwalbe Pro One 28c, but compatible with any tubeless or clincher tyre from 23 up to 45c.</i>
<h1>Wind Tunnel Tested</h1><i>Developed by HUNT's in-house engineering team, with years in the wind tunnel spent testing every last detail. We've left no stone unturned in designing this wheelset from the ground up to be very fastest in the world within its class.</i>
<h1>Real World Tested</h1><i>The fastest wheels ever down the Trouée d'Arenberg, the most hallowed (and, alongside Mons-en-Pévéle & Carrefour de l'Arbre, the hardest) of the cobbled sectors used in the Paris Roubaix. Nothing tests the limits of a wheelset like pavé.</i>

HUNT 48 Limitless Aero Disc Wheelset

48 Deep | 35 Wide Ext | 22.5 Wide Int | 1618g | CeramicSpeed

The world's fastest disc-brake wheels up to (and including) 50mm.

48 DEEP | 35 WIDE EXT | 22.5 WIDE INT | 1618G | CeramicSpeed

The Purpose

The ultimate aerodynamic wheelset. Designed by HUNT's in-house engineering team to meet the needs of the modern rider, at the speeds they ride at. We ride at a range of wind yaw angles far greater than previously considered, and so HUNT Limitless is able to deliver aerodynamic supremacy across a wide range of riding and at real-world speeds.

WIDER TIRES & WIDER WHEELS | RIDE FASTER

Leading rim-brake wheels have been at the 27-28mm wide mark for some time, with undisputed aero benefits over narrower designs. However, they are aerodynamically limited by rim brake calipers limiting the maximum width of the brake track. Further, most are optimised for narrower tires. 23mm tires used to be the standard… but for us, you and most pro riders, 25/28 and even 30mm tires are the preferred choice. Let’s face it: when leaning in on the final turn of a mass bunch sprint or descending sweeping alpine bends, you want serious grip! Plus, the lower rolling resistance benefits of 25 and 28mm tires* mean that road disc aero wheels should be specifically designed around these wider tires. Accordingly, this wheelset has been designed using schematics and feedback from Schwalbe's own engineers.
(*Especially rider-system benefits, wheel & tire only tests do not include rider damped losses, and how lower pressures reduce these losses by reducing rider movement. This is a whole other area we will be releasing scientific data on.)

HOW WIDE? 34.5mm!

In the last 9 months, road aero disc-brake rim widths have been creeping out to 30-32mm, with several leading wheel and bike companies realizing the benefits of having a rim wider than the tire (even a 28mm tire). This creates the most effective overall aerofoil shape (when considering the wheel and tire together) and reduces turbulence as airflow transitions into the spoke bed. It is now obvious that disc-brake road rims need to be significantly wider to be at their best aerodynamically. With our experience at HUNT, we knew disc brakes provided us a huge opportunity to smash open this area of wheel development. In autumn 2017, a full year before anyone knew about any other wheel companies’ 30mm+ development, we set about unleashing wheel widths, and HUNT's in-house engineering team designed several 3D-printed prototypes for wind tunnel testing. We worked closely with Europe’s leading bicycle wind tunnel, and over 18 months of painstaking research, design and multiple wind tunnel visits, developed the 34.5mm wide shape for the new 48 Limitless Aero Disc.

WIDE RIM = WEIGHT OR TIRE PROBLEM?

The aero benefits of going wide, can come with downsides, as usually a compromise choice has to be made:

- Go for a wider internal rim of 24 or 25mm = LOSE TIRE COMPATABILITY with 23/25mm tires from leading brands.

- Choose to add extra carbon material to thicken the sidewalls, in order to maintain the wide aero shape = HEAVY RIM WEIGHT

THE SOLUTION | HUNT LIMITLESS TECHNOLOGY

The HUNT 48 Limitless Aero Disc rim has as much carbon-fibre material and mass as any other comparable road disc wheelset, and far surpasses ISO impact testing. Added to the sidewall area is an extra-strengthening co-molded low density polymer (density only 0.7g/cm3 vs carbon fibre prepreg of 1.6g/cm3) that keeps the weight low whilst allowing the extra width. LIMITLESS is a patent owned by HUNT and developed by HUNT's in-house engineering team, Tom and Pete, and is exclusive to HUNT wheels. So, you can have a wheelset with the world’s fastest aero shape but also impressively low weight.

THE RESULTS…

The wind tunnel data we recorded is shown against the full range of incumbent world-class aero wheels in the charts below. The results speak for themselves. It’s been hard work but it’s been very worthwhile.

Plus, the lower rolling resistance benefits of 25 and 28mm tires* mean that road disc aero wheels should be specifically designed around these wider tires. Accordingly, this wheelset has been designed using schematics and feedback from Schwalbe's own engineers.
    (*Especially rider-system benefits, wheel & tire only tests do not include rider damped losses, and how lower pressures reduce these losses by reducing rider movement. This is a whole other area we will be releasing scientific data on.)

    HOW WIDE? 34.5mm!

    In the last 9 months, road aero disc-brake rim widths have been creeping out to 30-32mm, with several leading wheel and bike companies realizing the benefits of having a rim wider than the tire (even a 28mm tire). This creates the most effective overall aerofoil shape (when considering the wheel and tire together) and reduces turbulence as airflow transitions into the spoke bed. It is now obvious that disc-brake road rims need to be significantly wider to be at their best aerodynamically. With our experience at HUNT, we knew disc brakes provided us a huge opportunity to smash open this area of wheel development. In autumn 2017, a full year before anyone knew about any other wheel companies’ 30mm+ development, we set about unleashing wheel widths, and HUNT's in-house engineering team designed several 3D-printed prototypes for wind tunnel testing. We worked closely with Europe’s leading bicycle wind tunnel, and over 18 months of painstaking research, design and multiple wind tunnel visits, developed the 34.5mm wide shape for the new 48 Limitless Aero Disc.

    WIDE RIM = WEIGHT OR TIRE PROBLEM?

    The aero benefits of going wide, can come with downsides, as usually a compromise choice has to be made:

    - Go for a wider internal rim of 24 or 25mm = LOSE TIRE COMPATABILITY with 23/25mm tires from leading brands.

    - Choose to add extra carbon material to thicken the sidewalls, in order to maintain the wide aero shape = HEAVY RIM WEIGHT

    THE SOLUTION | HUNT LIMITLESS TECHNOLOGY

    The HUNT 48 Limitless Aero Disc rim has as much carbon-fibre material and mass as any other comparable road disc wheelset, and far surpasses ISO impact testing. Added to the sidewall area is an extra-strengthening co-molded low density polymer (density only 0.7g/cm3 vs carbon fibre prepreg of 1.6g/cm3) that keeps the weight low whilst allowing the extra width. LIMITLESS is a patent owned by HUNT and developed by HUNT's in-house engineering team, Tom and Pete, and is exclusive to HUNT wheels. So, you can have a wheelset with the world’s fastest aero shape but also impressively low weight.

    THE RESULTS…

    The wind tunnel data we recorded is shown against the full range of incumbent world-class aero wheels in the charts below. The results speak for themselves. It’s been hard work but it’s been very worthwhile. This process and the knowledge gained from pushing the boundaries of aero wheel development creates huge opportunities to serve you with a wide range of world leading aerodynamic wheels…this is just the beginning! Thank you.

    THE DATA

    Read the full research white paper showing all technical wind-tunnel testing method details, extensive wind tunnel data and the full range of wheels we tested.

    The Mavic WAD calculation is based around Time Trial speeds (45 km/h), we used this as an industry standard to show an unequivocal comparison. Our own road speed (35 km/h) simulations show the extra width of the LIMITLESS wheels provide even greater aerodynamic gains at the wider wind yaw angles that real road riders experience. Please see research white paper for more details.

    8.4 Fourth wind tunnel test

    The Enve Ses AR 3.4 Disc wheelset - In order to complete the test in a timely manner the tests were carried with the front wheels only, mounted on a single wheel turntable and roller, with no bike. Note that the total drag and power values are lower without the presence of a bike.

    "Hunt says its 48 Limitless Aero Disc wheels are the fastest disc brake-compatible road wheels up to and including 50mm deep, thanks to its patented Limitless technology. Going wide is the key apparently, and going by the way they perform out in the real world, Hunt could really be on to something. These wheels are quick!".

    On the road, these hoops lived up to their name, feeling markedly faster than our older Specialized Roval C38 discs. They roll remarkably well at 40km/h and beyond, needing what felt like less power to hold those speeds when compared to similar wheelsets we’ve tested.
