Classified x HUNT 48 Limitless Aero Disc Wheelset
48 Deep | 35 Wide Ext | 22.5 Wide Int | 1,501g (Including Classified Powershift rear hub shell)
THE WORLD'S FASTEST DISC-BRAKE WHEELS UP TO (AND INCLUDING) 50MM, NOW INTEGRATED WITH THE CLASSIFIED POWERSHIFT SYSTEM HUB SHELL.
48 DEEP | 35 WIDE EXT | 22.5 WIDE INT | 1,501g (Including Classified Powershift rear hub shell)
The Purpose
HUNT’s wide and stable, wind tunnel-proven aerodynamic wheelset is now available with the groundbreaking Classified Powershift-ready rear hub shell to create a versatile all-round road wheel system for those seeking every benefit that modern cycling techonology can offer.
Wind tunnel proven against world leading wheels. See the research white paper for full technical details of our wind tunnel testing methodology, including data/graphs and the full range of wheels we tested against.
Classified Powershift technology is a wireless shifting system that allows you to shift gears instantly and under full load. With an integrated Powershift rear hub, your riding will benefit from the range and functionality of a front derailleur and 2x drivetrain, while enjoying the simplicity and aero benefits of 1x setup.
HUNT LIMITLESS technology allows for low weight and extra-wide aerodynamics.
Includes FREE H_Care lifetime crash replacement for the first owners of these wheels. Read all about it here.
NOTE: The Classified Powershift internal system and electronics must be supplied by select Classified dealers. This wheelset does not contain the complete system. The rear wheel is delivered with the Classified hub shell, without the Powershift hub internals. Please contact our Rider Experience team with any questions.

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 tyres. 23mm tyres used to be the standard… but for us, you and most pro riders, 25/28 and even 30mm tyres 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 tyres* mean that road disc aero wheels should be specifically designed around these wider tyres. Accordingly, this wheelset has been designed using schematics and feedback from Schwalbe's own engineers.
(*Especially rider-system benefits, wheel & tyre 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 tyre (even a 28mm tyre). This creates the most effective overall aerofoil shape (when considering the wheel and tyre 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 TYRE 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 TYRE COMPATABILITY with 23/25mm tyres 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: 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.

"Road CC Editor's Choice""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!". |

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 tyres. 23mm tyres used to be the standard… but for us, you and most pro riders, 25/28 and even 30mm tyres 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 tyres* mean that road disc aero wheels should be specifically designed around these wider tyres. Accordingly, this wheelset has been designed using schematics and feedback from Schwalbe's own engineers.
(*Especially rider-system benefits, wheel & tyre 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.)

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.

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 125kg (system weight – total weight of fully kitted up rider, bike and luggage). If a rider is over 105Kgs then an experienced bike mechanic should check the wheel regularly and it is advisable to use tyres at max 90psi as this will reduce the fatigue on the wheelset.

"Road CC Editor's Choice""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!". |

220 Triathlon 91% ReviewOn 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. |
