Hunt has launched a new range of Aerodynamicist wheelsets that combine class-leading aero efficiency (backed up by wind-tunnel testing) with low weight, at a lower price than their industry-leading rivals. Could these be the performance wheels we’ve been waiting for?
The updated Aerodynamicist wheel line is being launched in three sizes: 34mm, and 44/46mm and 54/58mm-depth combinations.
The wheelsets have Enduro bearings as standard, as well as carbon and steel spoke options.
The new hooked rim design, which has been optimised for 28-30mm road tyres, comes with claimed weights from 1,175g and prices starting at £1,149.
The new in-house engineered Aerodynamicist range differs from the Sussex wheel specialist’s high-end Limitless wheelsets. The new differential rim design is based around hooked rim profiles rather than hookless, a standard Hunt debuted back in 2016, alongside ENVE.
Going with a hooked design rather than hookless will be music to the ears of fans of clincher tyres. With brands still launching high-performance clincher tyres, the Aerodynamicist range could be the best option around.
Hunt’s aim with the new wheelsets was to match the previous-generation Aerodynamicist wheels across all sizes, but now optimised for larger tyres (from 28 to 30mm).
The Aerodynamicist has been developed over three years, with 47,000 hours of computer processing time alongside lots of wind-tunnel testing.
The new rim profiles come with a 22mm internal width across all heights, although, like the Limitless, the external widths vary across the sizes. The front and rear profiles also differ.
Hunt’s senior design engineer, Patrick Brown, told us this not only improves aerodynamic efficiency, but also helps reduce the mass in the rims, bringing down overall weight across all models.
The largest of the trio comes with a 54mm-deep, 31.7mm-wide front rim and a 58mm-deep, 30mm-wide rear. The all-rounder option comes with a 44mm-deep front and 30mm width, and a 46mm-deep rear with the same 30mm external width.
The lightest option comes with 34.5mm-deep rims, both with a 28.4mm external width.
All wheels come with a 22mm internal rim width.
The new Aerodynamicist range is available with either UD Carbon spokes or triple-butted aero wing steel spokes.
All wheels come with Hunt’s hubs, constructed from lightweight 6066-T6 aluminium with a 7075-T6 alloy axle. The rear hub comes with the H Ratchet 40T DBL freehub system.
The dual-sided ratchet has a 40-tooth drive interface for a nine-degree engagement. Hunt says the ratchet requires less shell material compared to the standard pawl system, making for a lighter hub.
The hubs come equipped with Enduro’s steel ABEC 5 cartridge bearings.
As before, the Aerodynamicist is available in two build options – the premium version with UD Carbon bladed spokes and a standard model with triple-butted aero wing steel spokes.
Hunt claims the new Aerodynamicist range, paired with a 28mm Schwalbe Pro One tyre, offers an average 1.4-watt (2%) saving compared to the previous models.
When benchmarked against industry-leading wheelsets, Hunt’s wind tunnel results were positive.
All the wheel sizes were tested in the wind tunnel using Mavic’s WAD (wind averaged drag) protocol to analyse the data. WAD is explained as “The time spent at any given yaw angle will be different, depending on the conditions and route”.
To give a consistent method of combining these yaw angles into a single (WAD) value, Mavic has developed and published a ‘ponderation law’.
Wind angles over 15 degrees are unusual (and the WAD takes this into account), but this is a situation where the steering moment experienced by the rider is accentuated, leading to a feeling of instability.
Above 15-degree yaw angles, although experienced less often, it can have a significant effect on aerodynamic performance if stalling has occurred, leading to airflow detachment.
In the shallowest 34/34 size, the Aerodynamicists were only outperformed in low aero drag (WAD) by Shimano’s Dura-Ace C36s, which bettered the Hunt wheels by 0.58W, although the Aerodynamicists weigh 172g less than Shimano’s 1,368g. The Hunts bettered Reserve’s 34/37, the DT Swiss ERC 1400 35, Campagnolo’s Bora Ultra WTC 35, Roval’s Alpinist CLX II and Mavic’s Cosmic 32.
In the 44/46 size, the Hunts topped the testing, besting Mavic’s Cosmic 45 SL, the ENVE Foundation 45, Zipp’s 353 NSW, the DT Swiss ERC 1400 45, Zipp’s 303 Firecrest and 303s and Campagnolo’s Bora WTO 45s. The difference between the top and bottom of the list, however, was a mere 2.47W (WAD). The Aerodynamicists are the lightest in this test group.
On the largest 54/58 wheels, the Aerodynamicist also topped the testing table, besting ENVE’s SES 4.5, Zipp’s 404 Firecrest, the Reserve 52/63, Shimano C50, Zipp 454 NSW and Roval’s Rapide CL II (round spoke version). The difference between the top and bottom of the range tested was 3.12W (WAD), and again, Hunt’s 54/48 was the lightest wheelset at this depth.

The US bicycle industry’s trade association, PeopleForBikes, says Trump’s tariffs will have “devastating impacts” on the industry if they aren’t adjusted in the short term, in an open letter addressed to the President.
PeopleForBikes represents more than 340 US manufacturers, suppliers and distributors of cycling products. Published this week, the open letter requests tariff relief or an exclusion process for bicycles and bicycle equipment.
“The current tariffs on complete bicycles and components used for assembly, imported from countries around the globe, will have devastating impacts on our industry if not adjusted in the near term. We are hearing concerns around additional layoffs and the risk of more companies closing their operations, including some of our few remaining domestic manufacturers,” the letter reads.
The tariffs announced by Donald Trump in early April have already begun to cause chaos in the cycling industry. Specialized and Trek have hiked prices in the US, while other brands have cancelled shipments, and Silca even described launching a product in the US as “not viable”.
While Trump has said his tariffs will boost US industry, PeopleForBikes warns that difficulties persist in moving the supply chain.
“[E]ach bicycle may have 200 or more component parts that are still primarily sourced from sub-suppliers in foreign countries,” PeopleForBikes explains. “Developing a domestic manufacturing base for this wide variety of components will take substantial time and capital investment at a time when capital is hard to come by and cash flow is tight. Even without new, additional tariffs, our industry was already projecting a 3.7% decrease in sales, driven by higher aggregate price levels and weaker consumer confidence.”
The trade association says that while the USA once made all the bicycles it needed domestically, this has not been the case for several decades. The letter says that since the mid-1990s, low-cost imports from China have threatened American companies, and that a combination of “unfair foreign competition and unwise U.S. trade policy” led to the closure of bicycle factories in the country.
According to a 2021 study, 87 per cent of bikes imported to the US are from China.
PeopleForBikes says it appreciates President Trump’s “focus on China’s competitive threat” and closing of the de minimis loophole, which eliminates the duty-free import of low-value commodities “which has undermined the U.S. bicycle industry and local bike retailers across America for many years”.
The letter also outlines how US manufacturers are facing increased steel and aluminium prices from foreign and domestic sources, while the lack of domestic textile manufacturing could put cycling clothing manufacturers out of business.
Current and proposed tariffs on bicycle helmets is another issue the letter, sent on 29 April, raises. It says these tariffs “make buying this essential and legally required safety equipment much less affordable” and could leave cyclists without protection.
“The bicycle industry has enriched American lives for more than a century,” says PeopleForBikes president and CEO Jenn Dice. “We urge the administration to give our businesses the runway they need to compete globally, invest domestically, and keep biking safe, affordable, and accessible for everyone.”

Here’s what people were reading the most on FOSS Force during the month of April, 2025.
The post FOSS Force’s Top Ten for April appeared first on FOSS Force.
After a somewhat tumultuous switch to the
Server Side Public License (SSPL) in March 2024, Redis has backtracked
and is now offering Redis under the
Affero GPLv3 (AGPLv3) starting with Redis 8, CEO Rowan Trollope
announced. The change back to an open-source license was led by Redis creator Salvatore
“antirez” Sanfillipo, who also contributed the new Vector Sets feature for
the release. He said:
I’ll be honest: I truly wanted the code I wrote for the new Vector Sets data type to be released under an open source license. Writing open source software is too rooted in me: I rarely wrote anything else in my career. I’m too old to start now. This may be childish, but I wrote Vector Sets with a huge amount of enthusiasm exactly because I knew Redis (and my new work) was going to be open source again.
I understand that the core of our work is to improve Redis, to continue building a good system, useful, simple, able to change with the requirements of the software stack. Yet, returning back to an open source license is the basis for such efforts to be coherent with the Redis project, to be accepted by the user base, and to contribute to a human collective effort that is larger than any single company. So, honestly, while I can’t take credit for the license switch, I hope I contributed a little bit to it, because today I’m happy. I’m happy that Redis is open source software again, under the terms of the AGPLv3 license.
Since last year’s license switch, though, the Valkey project has sprung up as a fork under
the original 3-clause BSD license.
Last year Redis made the much criticized move to Redis Source Available License v2 and Server Side Public License v1 (SSPL) licensing. The move was widely panned by the open-source community and led to the Linux Foundation forking it as Valkey and also other forks like Redict coming about. In the months since many Linux distributions have switched from Redis to Valkey. Now Redis Labs announced today that with the Redis 8.0 release, they are adding AGPLv3 to the licensing mix…
