Good and affordable: that's the motto of the Radon Regard. The gravel bike comes with high-quality, lightweight components and is still more than affordable. The mail order company also offers its aluminium gravel bike in two full-equipment versions (1599 and 1799 euros). The 200 euro surcharge for the version we tested is money well spent, because in addition to higher quality Shimano GRX shifting components, there are also more powerful brake discs and a brighter headlight from Busch&Müller.
A bell and a sturdy kickstand are also included, while the mudguards and pannier rack come from Cube's own brand Acid and are identical to those of the Cube Nuroad FE, except for the simple headlight, which looks a little cheap on the Radon. This leads to the same points of criticism with the Radon: Here too, the rear mudguard in particular is short, and overall the mudguards are a little narrow for the width of the tyres, so that some spray water always flies past them on wet roads. We also find the position of the front headlight on the handlebars less than ideal.
The Radon Regard is a lightweight
The Radon scores many plus points with its frameset, which is one of the lightest on the market. The lightweight aluminium frame and the full carbon fork put the model in first place in the weight ranking despite its low price, even just ahead of the significantly more expensive Rose.
The fact that the frame with its simple shapes, round seat post, classic Ahead stem and externally routed cables looks a little out of date is not necessarily a disadvantage. The bike is much easier to maintain and adjust than the integrated solutions from Bergamont and Rose - the stem length and handlebar height can be changed in just a few simple steps.
However, the frame geometry puts the rider in an emphatically upright riding position even in the basic setting; this bike does not allow for a truly sporty, road bike-like position. Once on the move, the Radon Regard convinces with stoic straight-line stability and requires little concentration even on rough terrain.
Agile manoeuvres, on the other hand, are not its strong point. The chunky Conti tyres offer a lot of comfort and grip on loose surfaces, but roll more slowly on asphalt than the competition from Schwalbe, which is usually fitted to other bikes and has less tread.
