About the wheelset
Cadex is further expanding its product line in the gravel segment and is launching the AR 35 an ultra-light carbon wheelset onto the market. At a measured 1333 grams (Shimano freewheel), the carbon innovation is based on high-quality road models, while the wide rim allows for voluminous tyres of up to 45 millimetres. The inner rim width of 25 millimetres ensures a round tyre shape, which supports the sidewall, especially when cornering. The shorter but wider contact surface of the tyre minimises rolling resistance and increases riding comfort. Hubs with smooth-running ceramic bearings and carbon spokes optimised for aerodynamics round off the fast overall package of the Cadex AR 35. However, so much high-tech has its price: the wheelset from the Giant accessories brand costs 2599.80 euros.
Tyre mounting on the hookless rims
The tyres of choice for the event were Schwalbe G-One R in the 40 millimetre wide version. The experienced TOUR test lab mechanic was able to fit the tyres without any problems and without a tyre lever. Finally, the sealant was filled in and the tyres pumped up to around 2.0 bar. With the compressed air from the compressor, the tyres quickly found their position in the rim with an inner rim width of 25 millimetres. A final fine adjustment of the tyres on the hookless rim was carried out using the hands. Within a few minutes, the wheels were ready for use. The tyres and rims held the air reliably right from the start.
First impression of the Cadex AR 35 wheelset
With the new wheelset, the Veloheld Icon.X already made a completely new impression visually. The initial riding experience was promising, the tyres and wheels rolled easily over the local gravel paths. The lightweight wheels responded directly to every acceleration and accelerated smoothly. The only thing I had to get used to was the sound of the 60-tooth disc freewheel, which echoed a lot and I didn't recognise it as my own at first.
By bike on the train
On the way to Ljubljana, there were brief moments of anxiety due to the unfamiliar wheelset. This was due to the suspension devices in the trains. The fully loaded bike weighed between 16 and 17 kilograms and this weight was suspended from the front wheel between other gravel bikes travelling on the same mission. This meant lifting the heavy wheel, then threading the hook between the spokes and suspending the wheel - without damaging the tubeless valve or the carbon spokes.
The Cadex AR 35 at the bikepacking race
I was still cautious at first, not least because I had forgotten to pack sealing milk in case of a tyre puncture. Over time, I grew to trust the wheels, the tyres and myself more and more and rode down the often very bumpy and rocky descents with increasing speed. The impact resistance of the rim was put to the test several times: Some of the downhill sections were very rough and it was not always possible to see an ideal line quickly. This resulted in two punctures that did not damage the rim or tyre. In addition, stones kept flying sideways against the rim or spokes, resulting in nothing more than a loud thud.
The acceleration ability of the Cadex AR 35 carbon wheels had to prove itself less, because sprints were rather counterproductive for the overall performance after a good 800 kilometres with 15,000 metres of altitude.
Conclusion
The weight and specifications of the Cadex AR 35 not only provide a boost in the head, the lightweight also makes itself felt in terms of riding feel. The wheelset felt fast, comfortable and robust. If you are prepared to spend just under 2600 euros, this gravel wheelset will not only enhance the look of your bike.
