<h1>Rim Surface</h1><i>V:Absorbe resin reduces vibration and massively improves impact resistance. Disc brake rims are obviously not required to handle the high temperatures induced by prolonged rim braking. We have made the most of this and used our new V:Absorbe resin blends in the carbon layering which cures at a lower temperature. Lower temperature resins are less brittle meaning they have greater resistance to impacts and dampen vibration more effectively.</i>

<h1>Bearings</h1><i>The heart of any wheel. Investing in them makes huge sense. We use high-grade precision smooth-rolling sealed cartridge bearings by Japanese experts EZO. This wheelset has three of the rear hub bearings upgraded to S&S low-friction LU/LB seals on the internal bearing face to further reduce rolling resistance whilst maintaining excellent sealing on the exposed faces.</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 as time and money you spend fixing is time and money you cannot spend riding or upgrading your bikes. As a result 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.</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>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.. As Shimano hydraulic brakes are appearing on many new bikes, we wanted riders to have the option so we went even more adaptable with centre-lock hubs and 6 bolt adaptors included.</i>

<h1>Weight</h1><i>The consequence of the fanatical attention to detail is an outstandingly light 1458 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>

<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 with clincher tyres and inner tubes</i>

HUNT 4050 Carbon Aero Disc Wheelset

MIXED DEPTH PERFORMANCE, NOW IN DISC FORM.

40/50 Deep | 27 Wide | 1458g

The Purpose

Read the full aerodynamics report on the 50 Carbon Aero Disc

Many of you asked about us bringing the benefits of mixed depths over to our disc-brake range, and so of course we listened. Going deeper on the back provides additional aerodynamic advantages, but the shallower front end improves stability.

Pro road races, criteriums, and even time trials, are being won by disc-brake bikes with increasing frequency. The revolution is happening, and to capitalise you will need an aero wheelset that delivers speed in buckets. Introducing the 4050 Carbon Aero Disc. Read More

The super-wide 27mm rim provides superior aerodynamic performance. The U-profile serves up great handling and reduces drag across multiple wind yaw-angles. The extra-wide 19mm internal rim bed opens out your tire profile providing exceptional vibration reduction, grip and low rolling-resistance.

The straight pull hubs and bladed spokes reduce weight, add strength and respond instantly to your accelerations. The freehub body on the HUNT Sprint hub features 48 teeth on the ratchet ring, and treble-tooth pawls, providing incredible 7.5° engagement. Perfect for when the hammer goes down and you need an instant response. We’ve even upgraded to LU/LB bearings which are low-friction sealed on the internal face to further reduce rolling resistance and increase your speed whilst maintaining excellent sealing on the exposed faces. The latest breed of tubeless tires give-up nothing in weight to their clincher counterparts, as well as removing the tube for weight saving and reducing rolling resistance, so tubeless was essential.Read Less

The Experts' View

Want to add tubeless tires?

We can supply or fit tubeless tires (including sealant) to your wheels.

The wheels are also designed to work excellently with clincher tires and tubes. See recommended tire options here.

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. Please do not exceed the maximum pressure stated on your tire. Click here to listen to a podcast exploring the science of why lower pressures were found to be faster by pro teams.

Warranty, HUNT Rolling Road Tests & Weight Limits

A full 3 years from purchase date warranty is offered to the original purchaser only on all Hunt bike wheels against material or workmanship defects, please click here to read full details.

All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. 109kgs 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 90Kgs 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. Please note we cannot offer refunds on wheels that have suffered from crash damage but do offer a crash replacement discount.

Tubeless Tire Options

Schwalbe Pro One Tubeless Tires - 23, 25 or 28mm

The Schwalbe Tubeless road tires consistently win plaudits from journalists and customers alike. We have been testing them for a long time and have been very impressed. The One Pro's are Schwalbe's top of the range tires and feature their triple compound tread so you get extremely low rolling-resistance combined with excellent grip and durability.

Schwalbe G One Speed Tubeless Tires - 30mm

Unleashing profile and breathtakingly fast - especially when large volume counts. As a 30mm wide road race version with V-Guard, G-One Speed is a tire for the real tough jobs. You can ride it as a handmade tubular or with the most modern tubeless easy technology. But it is also a guarantee for maximum speed in the extra-wide 60mm execution - of course, not only at the fascinating beach races on Holland’s coasts. The new G-One Speed is an evolution of the former S-One and Big One.
