Hunt launches new carbon disc wheels

Three models added to the range: 30Carbon Aero Disc, 50 Carbon Aero Disc and 30 Carbon Gravel Disc

Hunt Bike Wheels has released details of three new carbon-fibre aero wheelsets that are all disc brake compatible. There are lightweight options in 30mm and 50mm rim depths, and a 30mm-deep cyclocross/gravel model.

The Hunt 30Carbon Aero Disc and the Hunt 50Carbon Aero Disc are essentially the same wheels featuring the same technology, it’s just the rim depths that are different.

They both have new disc-specific rims. Clearly, you don’t need a brake track on a disc-specific rim, but there are other differences from a rim-brake design too. The shoulders of the rim don’t need to be as reinforced on a disc brake model because they don’t need to withstand the forces from the brake, and heat buildup is far less of an issue. Heat can increase the pressure from within the tyre on a rim brake design, but that’s not a problem with a disc brake rim. 


Hunt says that all these factors allow it to drop the weight of a disc brake rim considerably over a rim brake model.

The new Hunt rims are made from unidirectional T24/30 carbon-fibre with 3K reinforcement around the spoke holes. 

The 30Carbon Aero Disc and the 50Carbon Aero Disc rims are both wide – 26.6mm external, 21.3mm internal – the idea being to create a broader tyre profile to increase grip and lower rolling resistance. A Schwalbe Pro One 25mm tyre inflated to 80psi measures about 29mm wide on these rims, and it’s lighter than switching to a 28mm tyre, for example.

The wheels feature an H-Lock tubeless-ready rim bed profile with ‘up-kicks’ to the shoulders of the tubeless steps. The idea is that these create a seal that makes initial installation of the tubeless tyres easier.

Hunt says the lack of heat build up means that, compared to rim brake rims, disc-specific rims can use lower Tg resins (Tg is the glass transition temperature, the point at which it becomes flexible and rubbery) that are less brittle so they have greater resistance to impacts. These resins are more able to absorb vibration from the road too, according to Hunt, which ultimately results in reduced rider fatigue. Marginal gains, innit!

This is one of many reasons why Hunt advocates the use of tubeless tyres run at low pressures for many riders. Hunt believes that reduced vibration from the road saves a significant amount of rider energy. 

As you can see, the rim profile is very blunt, the idea being to improve the aerodynamic performance at both the points where the tyre is leading and where the rim is leading.

The wheels use Hunt’s existing Race Season Disc hubs that are adaptable for every type of axle. They are centrelock with six bolt disc adaptors included. 

The spokes, 24 front and rear, are Pillar PSR X-TRA Aero straight pull.

We put the 30Carbon Aero Disc wheels on the scales here at when Hunt came visiting yesterday. The rear was 744g and the front was 594g, giving a total of just 1,338g.

The 50Carbon Aero Disc wheelset is 1,438g – 50g heavier per rim.

The 30Carbon Gravel Disc is a similar proposition to the 30Carbon Aero Disc, the key differences being that you get 28 J-bend spokes front and rear, and a higher level of protection for the bearings. They’re dual full-contact sealed.


The increased spoke count means that the maximum rider weight limit is increased from 95kg to 110kg. 

Hunt claims a wheelset weight of 1,489g.

The 30Carbon Gravel Disc Hunt and the 30Carbon Aero Disc wheelsets are each priced at £999 and can be pre-ordered now for delivery in October and November respectively.

The 50Carbon Aero Disc wheels are £1,099. They can be pre-ordered now for delivery in January.

Here's a video we did on Facebook Live with Tom from Hunt when he came in to show us the new wheels yesterday. Apologies that the picture is on its side for the first few seconds!

I like my Mason X Hunt wheels.  1 But I'm not going to buy another clincher wheelset. Patiently waiting for Hunt to finally do some nice tubular wheels.

To be honest, these look amazing. 30mm ones seem to be climber's wheel while 50mm ones are also very light. I think lightest in the class, compared with top class efforts from Mavic, Enve, Zipp and the likes.

What interests me is longevity of the package - hubs, spokes etc. It would be cool if some owners come with some comments and also how easy it is to service/replace bearings/hubs/spokes.

Personally, if I would get new wheels now from Hunt, I'd be stuck between the following:

-Aluminium Aero Disc wheel (28mm deep) - circa 470 GBP, playing safe (with lots of winter riding in mind).


-C30 gravel (due to more spokes and better bearing protection).

Ogi if you're still out there after 3 years - 

Gravel disk wheelsets - 3 years of CX racing in really bad conditions (UK mud, grit and water) and I haven't even had to change the bearings yet.  The front came out of true when I lept over the bars and landed on the wheel (nearly broke a rib, moved the wheel out of true by 5mm.  I'm 98kg inc shoes etc).

MTB 29er wheels - just keep rolling along.  Completely uneventful and trouble free.  

Carbon 50 disc - that's what happens next.  Had them for 2 weeks and loving them so far.  Replaced a Prime Black 50.
