What will it be - better aerodynamics, lower weight with fluffy comfort, or maximum durability? Custom-made gravel carbon wheels for race, adventure, and e-gravel bikes under review. 03.06.24 06:36 353

When I received my first DT Swiss GRC 1400 SPLINE 42 wheels for testing in Switzerland in 2019, I could never have dreamed how much they would shape my then still young "gravel career". Back from the hardcore stages through the Swiss Jura in the nastiest weather, I immediately requested a set of wheels for a long-term test. These would prove themselves over two years on my OPEN WI.DE. GRX 1x11 Di2, another two years on the Scott Addict Gravel GRX 2x11 Di2, on numerous test bikes and recently even on my latest offspring, a Merida Silex GRX 1x12.

About a year after the first story, I was asked if I knew when I could return the wheels. I did not know. Instead, I rode them with Tubolitos, Aerothans, Sealant, Schwalbes, Michelins, Pirellis, Challengers, and Vredesteins, with HG or Microspline freehubs. I had impacts, punctures and even once a branch in the front wheel along with a major flip. The result? They still roll perfectly and to this day I can't think of a single good reason to voluntarily send them back... if it weren't for the Swiss having recently presented their brand new DT Swiss GRC 1100 DICUT or 1400 DICUT in two rim heights.

GRC 50, GRC 30 & HGC 30

Under the motto "Off the road, are you on the hunt or off the hook?" DT Swiss fans now have a choice of three new gravel wheelsets in different equipment variants and wheel sizes.

Gravel Racers ("On the hunt") will choose the GRC DICUT 50 wheelset, which with its 50 mm high carbon rims, thanks to AERO+ optimization, is supposed to be among the fastest of its kind worldwide (see the Aerodynamics section below). In addition, the sleek rim shape significantly reduces steering influences even with 40 mm wide tires and offers a solid tire fit with an internal rim width of 24 mm for full control.

Adventurers ("Off the hook") will opt for the GRC DICUT 30 wheels, which with the reduced weight of the 30 mm high carbon rims provide an agile, comfortable ride and guarantee perfect traction off-road even at lower tire pressures. Moreover, their even wider manufactured flanges increase both puncture protection and durability.

Last but not least, for all E-Gravel bikers, the Swiss have developed the HGC 1400 SPLINE wheelset, which is based on the new 30 mm high gravel rim and is ideally suited for the requirements of hybrid bikes and the higher system weight with specifically reinforced components.

All three newcomers share a new, patent-pending carbon manufacturing concept, user-friendly hook rims for increased safety, consistently high-quality system components, and a sophisticated finish.

 Off the road, are you on the hunt or off the hook? 

Approximate translation: Off the road - are you chasing best times or letting loose?

Technology

Detailansicht

The patented, revolutionary carbon rim manufacturing process of the new gravel wheels offers several advantages. Not only can the rims be manufactured in a single operation, where the fibers of the outer layers do not need to be cut or individual components glued, but the Swiss "in-house" development also makes cosmetic post-processing or a final coat of paint unnecessary. This saves weight and ensures a high-quality finish without air pockets or uncontrolled resin accumulations.

Moreover, the quality of each rim is checked 100% through all layers, and only rims without any material defects are released for the final wheel system assembly. This always keeps the customer on the safe side.

Because the Swiss are convinced that hooked rims are the ultimate solution for roadies when it comes to safety and user-friendliness, all DT Swiss road wheels are now equipped with flanges in these three models. Compared to hookless rims, hooked rims are more forgiving of faulty applications in terms of pressure and tire compatibility, and the tire maintains better grip on the rim in all situations. Additionally, CFD simulations and wind tunnel tests show a clear aerodynamic advantage of wheel-tire systems with hooked rims due to reduced air resistance and more controlled steering torque. The only challenge remaining is the development and production by the manufacturer.

Both the 180 and 240 hubs impress with their DT Swiss Ratchet EXP Technology, which makes the freewheel body particularly light, stiff, and precise, and allows for easy, tool-free maintenance. Moreover, the hollow-milled tooth discs immediately convert the invested energy into acceleration with their 36 teeth.

For all three gravel wheels with a 24 mm internal width, a tire recommendation of 29 mm to 45 mm width applies, while the GRC 50 with its external width of 36.5 mm should perform best aerodynamically with 40 mm wide tires.

Aerodynamics - 50 mm make you faster than ever before

For a long time, the development of aerodynamic wheels has not only been about the fastest rim design, but rather about the optimal interaction of the individual components with tires, frame, and rider. That's why, in 2018, DT Swiss entered into a strategic partnership with Jean-Paul Ballard from Swiss Side, a former Formula 1 aerodynamics specialist and avid triathlete. Together, they aim to establish the best performance and highest quality at an affordable price. No gimmicks. No irrelevant technologies that do not add value make it into the final product.

According to JP, during time trials, about 69% of the total resistance is due to air resistance, while this value is still around 51% when gravel biking. Reason enough to optimize the entire wheel system, including the wide gravel tires.

Drag Performance

Taking all factors into account ultimately led to both new rim shapes, with the S-shape of the GRC 50 wheels with a 24 mm internal width and 36.5 mm external width standing out in particular. This shape is intended to offer the best compromise between aerodynamic performance and robustness, setting new standards in direct comparison with the competition.

Detailansicht

Drag Performance: The graphic shows that the new GRC 50 with the Semislick RS 40C has the best aerodynamic performance across all angles of attack.

Measurements were once again taken in the GST wind tunnel with the Schwalbe G-One RS 40C at 37.5 km/h. Compared to the GRC 30 front wheel, the weighted air resistance is 14.9 watts, which corresponds to an advantage of 2.6 watts (15%) and - despite the higher rim - a slightly better steering moment.

  • DT Swiss GRC 50, GRC 30 & HGC 30 Gravel Wheelsets

GRC 30 (NEW) vs. GRC 42 (OLD)

On the other hand, the GRC 30 are roughly at the aerodynamic level of the earlier GRC 42, but are significantly lighter, more comfortable, and more durable. An interesting detail on the side is the rule of thumb that wider tires increase air resistance by 3.6 watts per 10 mm and measurably reduce the sailing effect. The higher the tread knobs, the poorer the performance.

Steering Moment Analysis

In addition to pure air resistance, side winds continuously exert forces on the wheel and can affect rideability. Therefore, the riding behavior must be safe and predictable regardless of external weather conditions such as strong and changing cross and headwinds. The lower the steering moment, the more the road cyclist benefits from predictable and thus controlled steering behavior, stays longer in the aerodynamically optimal position, and achieves higher speeds.

Detailansicht

Steering Moment Analysis: In steering moment as well, the GRC 50 are ahead, which is especially advantageous in gusty winds. According to this chart, lighter riders should at least avoid the ZIPP 353 NSW with gravel tires.

Comfort & Durability - 30 mm opens up new adventures

Those who focus on reduced weight, more comfort, or lower tire pressure can make their gravel bike adventure-ready with the GRC 30 wheels. The newly developed rim shape, with a height of 30 mm, reduces the weight of the wheels while optimizing air resistance. The internal rim width of 24 mm is the same for both rims - ideal for high sidewall stability when using 40 mm wide gravel tires.

GRC 50 or GRC 30 for NoPains Merida Silex?

We are writing the month of April in the year 2024. NoPain is at the DT Swiss headquarters in Biel, attending the highly confidential presentation of the even more secretive GRC gravel wheels. While his international press colleagues attentively follow the words of the CEOs, as well as the product, R&D, and marketing managers, NoPain starts his mind's cinema: "Need it"... "Want it"... "1100 DICUT is a given, I'm not paying anyway... but 50 or 30?"... "Damn!", "50 or 30...?"

On one hand, he really likes the tall 50s with their technocratic S-Shape. Better aerodynamics are always worthwhile, and the idea of more controlled steering torque is equally tempting. However, a weight difference of just over 200 grams compared to the 30s is also not negligible. And real races, well, he doesn't race anyway. Therefore, the 30s would definitely be more suitable. But the 50s were indeed beautiful. It was maddening.

A surprisingly clear decision for NoPain

Subsequently, all attending journalists were given the opportunity to test both wheelsets with identical tires and the same tire pressure on two designated courses. On one side, a route rich in elevation with rugged forest and meadow trails, and on the other, a longer, flatter, and faster variant over fields and farm tracks.

The result was surprisingly clear. While the GRC 50 logically could leverage their aero performance on the fast sections, they were somewhat sluggish on steep climbs and noticeably jolted colleague NoPain on the root trails. The 30s, on the other hand, felt nimble and noticeably better absorbed the rough bumps compared to the higher aero wheels. In terms of aerodynamics, he noticed at most that the latter produced slightly less sailing effect, and that only on the flat passages with a lot of crosswind.

In short: Overall, the GRC 30 provided more riding fun and were additionally about just over 200 grams lighter. DEAL!

Light is the new black

Although weight is not the sole decisive factor in gravel riding, one is still pleased about every additional gram saved, as it positively influences agility and steering comfort.

In our research, we came across the following comparison of all current DT Swiss gravel wheels, which we naturally do not want to withhold from you.

And indeed - the direct comparison of our ready-to-ride GRC 42 predecessors (Tubolito tubes) with the new GRC 30 test wheels (TLR incl. Sealant) resulted in a real weight advantage of 233 grams.

Since May 2024 in the review,... and probably until the next GRC evolution in the year of snow

  • DT Swiss GRC 50, GRC 30 & HGC 30 Gravel Wheelsets

In practice

When I received the GRC 30 wheels, they were already equipped with Schwalbe G-One R in 40C and filled with DT Swiss "Low Pressure" Sealant. These were the same wheels, hand-built in Biel, that I had the pleasure to ride during the presentation in Switzerland. Into the bike, photos in the studio, and off to the first ride with NoSane.

No joke - the direct switch from my old GRC 1400 42 with G-One R/RS in 45C to the new, lower wheels with the G-One R front and back (!) in 40C blew me away so much that I was at a loss for words. These things rushed over asphalt and gravel so much that I initially suspected NoSane of secretly pushing me. But even then, when he rode in front of me, the thrust just didn't stop. Tailwind maybe? Could be, but even with a slight headwind, they took off like Schmidt's cat. I was flabbergasted.

  • DT Swiss GRC 50, GRC 30 & HGC 30 Gravel Wheelsets

Twilight Zone

Even after five longer rides, I still have no conclusive explanation for it. It's probably due to the combination of the 5mm narrower tires with the sealant instead of tubes, the slightly higher pressure of 0.25 bar, improved aerodynamics, and the 233 grams lower total weight. Maybe someone secretly installed ceramic ball bearings into the 180 hubs and the EXP freehub. I don't know and I don't really care. I just ride and enjoy.

Moreover, I can't notice any loss of comfort despite the 40C tires instead of the 45C tires. Probably, the obvious deterioration (narrower contact area, less volume, ridden with more pressure) is compensated by the higher vertical flex of the lower rims and the longer spokes.

Overall, apart from the somewhat "slower" look compared to the 50s, I am more than satisfied with the GRC 1100 DICUT 30 and feel even slightly faster in my terrain, as they run smoother and more precise off-road than the higher model variant.

+ Stiff and light
+ Comfortable (24 mm inside)
+ Aerodynamically optimized
+ High-quality components
+ Extremely agile with controlled steering behavior
+ Highest durability
+ Every adventurer’s dream
+ Uncompromising GRC 50 variant available for racers
+ Elegant, exclusive look
+ 650B and 700C variant
- High price in the best execution (1100 DICUT)
BB-Verdict: Incredibly fast, despite being maximally designed for agility, comfort, and durability.


Those who do not want to leave anything to chance in their adventures opt for the new GRC 1100 DICUT with the 30-mm rim. They are not only a real eye-catcher, but also save valuable grams besides their special aero optimization. With the light 180 DICUT hub and DT Aerolite II spokes, they guarantee high agility as well as good acceleration, and with the right tires, thanks to a 24-mm internal width, they also ensure low rolling resistance.

The susceptibility to crosswinds is unnoticeable, and the comfort on poor surfaces is great. The absolute strength of these wheels, as already mentioned, lies in their all-round capabilities - from fast after-work rides to crossing the Gobi Desert with full gear.

Those who tend to ride in flatter and faster terrain or on firmer grounds, or even want to compete in gravel races, are better off choosing the 50-mm-high wheels. These not only allow for a 15% better aerodynamics but can be controlled slightly more when steering in strong winds with 40C tires.

Ultimately, one can hardly go wrong with either variant. For passionate gravel bikers and all those who want to become one, a clear buying recommendation. The price of the top variants does hurt a bit, but since the wheels are expected to last many years, it really doesn’t matter much in the end.
