Test 2015: Radon Black Sin 29 Supreme
Why do Germans prefer to shop at Aldi? Of course, because the price is right. But if the products were only cheap, they wouldn't be so popular. No, the quality of Aldi products also puts many an expensive branded product in the shade. Radon secures such a price advantage through its direct sales.

This allows the Bonn-based mail order company to bolt components such as Rock Shox's upside-down fork, an XX1 drivetrain and carbon parts from Syntace onto their Black Sin without the price exploding. But the 1302 gram frame, which is large, has nothing to hide with its laboratory values either. In order to tune the acceleration values, the gram-harvesters will put latex milk in the Conti tyres. But the good-natured character should please even stubborn discounter deniers. Because on the trail, the Black Sin can forgive a wrong line or a missed braking point.


ConclusionRadon, the mail-order company, equips its good-natured racer with everything that is exclusive and expensive.


PLUS Relatively inexpensive, carbon wheels, good tyre combination, large frame mudguard on the bottom bracket, good-natured handling
MINUS Only three frame heights, large 34 mm chainring


The alternative For a mechanical XTR groupset (2x), a Fox 32 and Mavic Crossmax SL wheels, you pay 3799 euros for the Black Sin 10.0. For this, you get a top hardtail weighing 9.4 kilos.

Canyon, Radon, Trek, Cube: The RS-1 fork is stiff enough, sensitive and the travel can be fully utilised. However, the fork worked quite differently in some cases.Photo: Georg Grieshaber Canyon, Radon, Trek, Cube: The RS-1 fork is stiff enough, sensitive and the travel can be fully utilised.
