When a new wheel shows up at the shop, I don’t usually unbox it myself. This one I did.
We’ve heard rumblings for months – and in January Matthias told us it was official: Lightweight was doing something new. Not just a revision, but a complete ground up rebuild. This is their first full wheelset release in years: the Meilenstein ART.
ART = Alpha Rib Technology, Lightweight's all-new structural reinforcement method. Instead of a traditional hollow structure, ART introduces a network of integrated ribs inside the rim cavity. These structural elements dramatically increase lateral stiffness by reinforcing the cross-section against side loads. This means more efficient power transfer and precision-handling.
Lightweight doesn’t roll out products on a hype cycle or to fill a gap. Actually, for over 20 years, every iteration of the wheel played off of something before – ART is the first genuinely new Lightweight wheel innovation since the Gen 1 in 1995.

Opening the box, two things hit immediately: the raw finish and the structure. It’s clean, quiet, and unapologetically engineered. Like every Lightweight wheel, we can see the carbon architecture…but it’s a full departure from the exposed weave we’re used to on the Fernweg, Obermayer, and Meilenstein standard wheels. This is flat and refined – perhaps a slight design nod to the rest of the market where matte carbon is more or less the standard.

The rim profile is wider than you’d expect from Lightweight – 23mm is going right to the money shot. And the spokes bond straight into the hub: no extra hardware. On the inside (and especially at the hub) these are still very much Lightweight. Just evolved.
After a week of test rides in Marin – climbing, descending, cornering, crosswinds – I started to get it. These wheels are different.
They feel taut without being twitchy. Confident at speed. Tech specs say it’s 1,190 grams with a 45mm depth and a 23mm internal width. It fits my 28mm Veloflex tires perfectly, but should go up to about 34. (Per Lightweight, the minimum supported size is 28mm).
“You really notice the difference when you’re rolling under load,” said Matthias. He’s right.
They respond, but they don’t overreact. I could stay on the gas in corners and feel everything. And it holds shape well even in stiff sidewinds on Ridgecrest.
Ride Impressions
I’ve ridden very few wheels where the engineering story holds up on the road. This new Alpha Rib Technology (Lightweight’s internal structural ribs that replace foam cores) translates directly to how the wheel holds a line under pressure. The torsional stiffness is there when you stand and surge, but it never feels like you’re getting punished for riding less than 100 percent.
This is grip without the usual hum of overstiff carbon. The kind of feel I associate with rim brake climbing wheels from ten years ago – only faster. And disc. And bigger tires.
When we got these wheels a few weeks ahead of launch, AC was the only shop in the country with early access. I’m grateful Lightweight trusted us with that. I’ve been riding their wheels for over two decades, and I’ve seen every iteration. That history gives me a sense of what matters when something new lands. This one does.
We all liked the full aluminum hub right away. Just feels a bit more robust. And they continue with the latest iterations of DT Swiss’s freehub body – which makes cassette swaps and maintenance straightforward. One thing I loved is that the new design allows much cleaner brake rotor lockrings – like cassette-style lockrings – which mount flush. This is especially important if you’re running 140 rotors front and rear like I do. From an aesthetic standpoint, it’s slick.
The Meilenstein ARTs are not ultra-light by today’s chart-chasing standards, but it doesn’t matter. They feel ultra-light. More importantly, they feel precise. I’ve ridden just a few stiffer wheels, but very few that deliver that stiffness this smoothly.
I also noticed that these felt really stable in the wind. We had some massive winds during my time on the wheels and at no point did I feel pushed around.
Tires mounted easily, sealed immediately, and held pressure all week without a hitch. Lateral movement? None. Standing sprints? Instant. No rotor rub. And in high winds on Panoramic Highway, they stayed calm. No twitching or surprises.
The real surprise came on descents. The wheels track with confidence and respond predictably under load – there was no movement off the line unless I wanted to go there. Even braking felt a bit more confidence inspiring.
I'm not an engineer, so I can't say much on the work they did inside the rim, but I can feel it. Not a common thing these days where so many wheels feel the same for the most part. So nice to get something and instantly feel the difference. They have a character. It’s special. I think that’s becoming increasingly rare.
So here’s the long-view…
These wheels are a dear $8,500. No one’s pretending otherwise. But I’ve had a pair of tubular Lightweight wheels for over a decade that still ride like the day I got them. These feel like that kind of investment. You’ll put miles on them for years without chasing something “better” six months later.
Coming off what I still consider the second-best wheels on the market – the Meilenstein EVOs – I felt the difference immediately. If you’re upgrading from anything else, the gap will be even bigger.
Final thoughts
It’s rare that a product this complex lands this well on first release. Especially from a company that’s been as quiet as Lightweight. But this one’s sharp. Really sharp.
It doesn’t try to be everything, and it doesn’t chase gimmicks. It’s a wheelset for people who know what they’re looking for, and who are willing to ride it hard enough to find out why it matters.
There are 50 pairs available globally for launch. Reserve yours or let me know if you want to see them in person. We’ve got a pair in the shop.
→ Thanks again to Lightweight for letting us get real miles on them before the curtain lifted. This was a privilege.
