Wheels are not only eye-catching, but also an important part of the chassis. With their width, they determine the shape of the tyre and the air pressure with which it can be ridden. With the current wide rims - the average internal dimension in the test is around 30 millimetres - the pressure can be lowered and comfort and grip increased. These are strong arguments for retiring old narrow-track wheels and banishing them to a second or third bike and investing in new technology.
But which design should you choose? Conventional construction or system wheel? What weights are realistic? Can carbon rims survive a ride through rock gardens, or is it crazy to seriously rattle over rocks and root boards on carbon? Sure, everyone wants a light wheel. But wheels also need to be robust. Because if the wheel fails, the air is not only out of the tyre, but also out of the dream tour.

Two wheels stand out in the test
In terms of stiffness, all wheels benefit from the Boost design. Thanks to the wide installation dimensions, the rims stand firmly between the flanges, even though the thinnest spokes such as the Sapim CX-Ray are used. System wheels, i.e. specially matched hubs, spokes and rims, realise slightly lower weights than conventional setups. The wheelsets weigh between 1400 and 1950 grams, with the aluminium model from Newmen weighing in at 1597 grams between the carbon wheels, which naturally lead the weight ranking. The crash test reveals major differences. Here, the carbon rim from Syntace (1600 grams) shows extreme resilience and remains intact even under hard overload, which causes aluminium rims to buckle like an empty can of beer. Together with the other good qualities, this gives it a "Super" in the overall ranking. All other carbon rims fail much earlier, at the latest at impact level 5, but sometimes show minor damage even before that, which is not always easy to detect, but can be a nucleus for total failure. With carbon, the question always arises as to whether the manufacturer can guarantee to have the manufacturing fluctuations typical of carbon under control. Aluminium is more honest in this respect. The material is homogeneous, and a large impact always results in a dent. Smaller dents can be bent out again, but if the flank breaks, as with Sun Ringlé, the tour is over. The size of the bumps varies greatly. Newcomer Newmen stands out in this discipline for aluminium bikes and also gets a "Super" as a final verdict. The dent resistance is much better than with all other rims, thanks to a slightly flared flank, copied from the motocross sector. In the duel of the best - Syntace and Newmen - there is almost a stalemate between carbon and aluminium wheels. However, the latter costs less than half as much and is therefore the best value for money in the test.
Conclusion Robert Kühnen, BIKE test editor:
Carbon is the material to make wheels as light as possible. But only by using a lot of fibre can they become so robust that their performance is beyond reproach. And then the weight advantage over the best aluminium wheels is gone. So common sense dictates that aluminium in its best form remains the first choice.
Wide rims
The average inner width of the rims is 30 millimetres, which allows low tyre pressures. The wide Boost installation dimension - 110 mm at the front, 148 mm at the rear - makes the wheels stiff.
Tubeless
All rims in the test are suitable for tubeless operation. However, the effective diameters vary. A slightly oversized rim is helpful for a good seal.
Breaking test: carbon breaks, aluminium dents
The eternal competition for the best material does not stop at the rims. Our impact test simulates what happens when aluminium or carbon make hard contact with the ground.
Missed a stone or jumped right into a root? If the tyre punctures, the structural strength of the rim is what counts. We carried out an impact test to see what the rim can withstand. To do this, we mounted the wheels at an angle of 20 degrees and hit the rim flange with a 7.5-kilogram plastic hammer from five different heights. Aluminium rims quickly get dents, the depth of which we measured (table values above). We checked carbon rims for visible damage and made up to five attempts at five different points at the highest impact level. Sometimes four attempts go well without damage, and the rim breaks on the fifth. In the case of carbon, we rated the highest damage-free level, and in the case of breakage, we also devalued by one level. In the case of aluminium, we rated the level at which the deformation remained below one millimetre.

Max. Rider weight / disc size 110 kg / 203 mm
MEASURED VALUES
Rim width (inside) / tyre fit 30.5 / 584.6 mm
Weight² VR 804 g / HR 928 g / total 1732 g
Stiffness VR 85.5 N/mm / HR 70.5 N/mm
Inertia VR 450 kg x cm² / HR 453 kg x cm²
Polar diagram VR / HR (spoke tension in Newtons, red: right side, blue: left side)
Spoke tension deviation VR 19/54 %, HR 27/11 %
Weight² (20 %) 7 out of 10 points
Inertia (10 %) 7 out of 10 points
Stiffness (20 %) 10 out of 10 points
Concentricity (10 %) 5 out of 10 points
Voltage distribution (10 %) 7 out of 10 points

Conclusion The large shoulder diameter ensures a tight tubeless fit. With plenty of spokes, the construction is very stiff. However, the flat rim flanges are not very impact-resistant.
