When the conversation turns to gravel riding, durability and capability often take center stage. But for riders who tackle long distances, the lightest gravel wheelset isn't just a vanity metric—it's a key to unlocking speed, comfort, and less fatigue on epic days. The pursuit of low weight has led to some truly remarkable builds, and the data and technology behind these components are more compelling than ever.
Why the Lightest Gravel Wheelset Matters on Long Rides？
On a long gravel ride, every gram you rotate matters more than static weight. A lighter wheelset accelerates faster, climbs more efficiently, and reduces the cumulative toll on your body over hours in the saddle. The benefits aren't just about raw speed:
-
Reduced rotational mass means less energy required to spin up to speed after every corner, washout, or steep pitch.
-
Lower fatigue comes from less muscle strain and micro-adjustments, especially on rough terrain.
-
Improved comfort often accompanies well-designed lightweight wheels, as they can be built with compliance in mind.
For ultra-endurance riders, the difference between a 1,500g and a 1,200g wheelset can be the difference between finishing strong and simply finishing.
The Extreme End: A 5.64kg Gravel Bike
While not a standalone wheelset review, a recent custom build of an S-Works Crux sheds light on just how far weight weenies will go. The builder, Twisted Wheels' Oleg Kononov, managed to create a complete gravel bike that weighs a staggering 5.64kg. Achieving this required modifications that go far beyond simply swapping components. The frame was stripped and repainted to save weight, and the fork was carefully modified and reinforced to allow for internal cable routing.
The build spec is a who's who of ultra-light components, including an Elilee X-Novanta crankset that weighs just 274 grams and a SRAM RED XPLR rear derailleur that was modified with a custom carbon cage and pulley wheels to drop an additional 34 grams. The battery itself was even replaced with a carbon fiber version, saving over 10 grams. This build demonstrates the lengths riders will go to for a lighter setup, but it also highlights a crucial trade-off: such extreme modifications often sacrifice warranty and durability for the sake of grams.
Roval Terra CLX III
The Roval Terra CLX III stands as one of the lightest production gravel wheelsets on the market, with a claimed weight of just 1,079g including tubeless rim tape and valves . This represents a significant achievement in balancing low weight with real-world durability.
The Terra CLX III rims are 25.5mm deep with a 38mm external and 27mm internal width . The bead hooks are 4.86mm, designed to offer flat resistance. Roval states that these wheels support 35-60mm tyres and are optimised for 40mm upwards . Perhaps most impressively, Roval claims the Terra CLX III offers 21.52% more compliance than its predecessor, making it not just light but genuinely comfortable on challenging terrain .
The wheelset uses composite Roval aero spokes by Arris and DT Swiss 180 EXP hub internals . The rims also feature a hooked bead profile specifically designed to prevent pinch flats, a detail borrowed from Roval's mountain bike wheel designs .
Berd Sparrow Carbon Gravel Wheels
The Berd Sparrow takes a fundamentally different approach to weight reduction, using Dyneema string spokes instead of traditional steel or carbon spokes . This unconventional design results in a verified weight of 1,140g for the pair, making it one of the lightest wheelsets tested regardless of cycling discipline .
The Berd Sparrow rims are 25mm deep with a 25mm internal width, and the design prioritizes minimal weight above all else . Each rim weighs a claimed 265g, and the complete rear wheel comes in at 640g while the front is just 500g . The Dyneema spokes weigh just 2.5g each—roughly half the weight of a quality steel spoke—and save approximately 100-200g in a complete wheel .
What makes the Berd Sparrow particularly interesting is its ride quality. The woven, flexible nature of the string spokes when not under tension gives the wheels a supple, smooth ride feel that's noticeably different from steel-spoked wheels . Despite this compliance, reviewers note that lateral stiffness hasn't been compromised—the wheels feel tight and stiff during hard efforts . The wheelset has a suggested rider weight limit of 250 pounds, which is remarkably generous for such a lightweight build .
Scribe Gravel Carbon 40 with Berd Spokes
The Scribe Gravel Carbon 40 offers a slightly more conventional rim depth (40mm) while still utilizing Berd's PolyLight string spokes. On the scales, this wheelset came in at 1,334g including tubeless rim tape, though not including valves .
The 40mm-deep Toray T700/T800 carbon fibre rim has an internal width of 24mm and an external width of 30.5mm, with 28 spokes front and rear . Scribe recommends tyre widths of 32mm to 50mm. The wheels use a ratchet-style freehub for rapid engagement and are available with all major freehub standards .
Reviewers praised the Scribe wheels for their excellent ride quality, noting that the supple feel is noticeable over high-frequency vibration surfaces like gravel . The wheels feel light when accelerating and climbing, and efficient pretty much anywhere. At £1,449, they also represent strong value compared to many premium competitors .
Tune Nano Gravel 45
The Tune Nano Gravel 45 from German lightweight specialists Tune checks multiple boxes: it's light at 1,335g for the pair, has a wide 30mm internal width, and features a hooked profile that works with both tube and tubeless setups .
The 45mm depth offers a balance between aerodynamic gain and stiffness, while the 30mm internal hooked rim provides reliable low-pressure support for modern gravel tyres . ETRTO officially classifies the wheels for 47-57mm tyres, but Tune's own testing shows secure fit from 38mm all the way up to 66mm . The wheelset uses Tune's Nano CL hubs with 5.2-degree engagement and a choice of steel or ceramic bearings, laced with Sapim CX-Ray spokes .
The Tune Nano Gravel 45 comes with a 10-year warranty, suggesting the brand has confidence in the durability of its lightweight design . It's positioned as a "Swiss Army Knife" of gravel wheels—equally suited for racing or everyday adventure riding.
Schmolke TLO Gravel
The Schmolke TLO Gravel weighs in at 1,290g, making it 162g lighter than the Zipp 303 XPLR SW in a direct comparison . The rims are 35mm deep with a 25mm internal width, designed for 40-45mm gravel tyres .
What sets the Schmolke apart is its hub choice: DT Swiss 180 hubs with SINC ceramic bearings and Ratchet EXP internals . This is a flagship-level hubset with widespread servicing support. The wheels are built with 28 Sapim CX-Ray spokes front and rear .
The Schmolke is made and built in Germany and priced at $4,495, positioning it as a premium option . For riders who prioritize low weight across the entire ride—climbs, accelerations, technical sections—the Schmolke offers a compelling package without the tyre restrictions that some aerodynamic gravel wheelsets impose.
The Trade-Offs: Weight vs. Aero vs. Durability
The pursuit of the lightest gravel wheelset inevitably involves trade-offs. Understanding these can help you make an informed decision for your riding style and terrain.
Weight vs. Aerodynamics
Deeper rims offer aerodynamic advantages, but at a weight penalty. However, research suggests that once tyre width exceeds 40mm, the aerodynamic benefit of deeper rims diminishes significantly . ENVE's own data indicates that with 40mm tyres, a deeper aero wheelset and a shallower lightweight wheelset are "essentially aerodynamically equal" .
This means for gravel riders using 40mm+ tyres—which is most of us—the weight savings of a shallower rim may deliver more real-world benefit than the marginal aero gains of a deeper profile.
Weight vs. Durability
Extreme weight reduction can compromise durability. The 5.64kg Crux build demonstrates this: modifications like stripped frame paint and custom carbon battery replacements sacrifice warranty and long-term reliability for the sake of grams. Production wheelsets like the Roval Terra CLX III and Tune Nano Gravel 45, however, manage to achieve impressive weight figures while maintaining warranties and real-world durability.
Compliance and Comfort
Lightweight wheels aren't inherently less comfortable. In fact, the Berd Sparrow and Scribe Gravel Carbon 40 both received praise for their supple ride quality, attributed to the flexible nature of their string spokes . Similarly, the Roval Terra CLX III was specifically designed with 21.52% more compliance than its predecessor . The key is in the engineering—lightweight wheels can be built to prioritize comfort alongside low weight.
What to Look For in a Lightweight Gravel Wheelset
If you're shopping for the lightest gravel wheelset that still meets your needs, here are the key considerations:
-
Weight per rim: Aim for wheelsets in the 1,100–1,400g range for a balance of lightness and strength. Below 1,100g, you're entering extreme territory that may compromise durability.
-
Internal width: Modern gravel wheels typically range from 24-30mm internal width. Wider rims support wider tyres with better shape, but check compatibility with your preferred tyre size.
-
Spoke type: Steel spokes are reliable and repairable. Carbon spokes save weight and can improve aerodynamics. Dyneema/string spokes offer the lowest weight and unique ride quality but may be more expensive to replace.
-
Hub quality: Lightweight hubs save grams, but engagement speed and bearing quality matter for performance and longevity. DT Swiss 180 and Tune hubs are proven options.
-
Tubeless compatibility: Essential for gravel. Look for wheels that set up easily tubeless and hold pressure reliably.
-
Warranty and support: A lightweight wheelset is only valuable if it lasts. Check the warranty period and the brand's reputation for customer service.
The Bottom Line
The lightest gravel wheelset isn't about chasing numbers on a scale—it's about making long rides easier, faster, and more enjoyable. While extreme builds like the 5.64kg Crux show what's possible when weight is the only consideration, production wheelsets like the Roval Terra CLX III (1,079g), Berd Sparrow (1,140g), Tune Nano Gravel 45 (1,335g), and Schmolke TLO Gravel (1,290g) demonstrate that you can achieve remarkable weight savings without sacrificing durability or real-world performance .
For most riders, the sweet spot lies in a well-engineered wheelset that balances grams, durability, and the specific demands of your terrain and riding style. Grams do matter, but only when they serve the ride.
