2Danger was a traditional private label of the German retailer B.O.C. (Bicycles Online/Stores), which was very popular in the 2000s and early 2010s. Racing bikes of this brand were typical, affordable sensible bikes with an excellent price-performance ratio, combining solid Far East aluminum or carbon frames with established brand components. Here is an overview of the typical characteristics and features of a 2Danger racing bike: Frame and construction Material: Mostly robust aluminum (e.g., 6061 alloy). The frames were considered stable, stiff, and durable, falling into the solid standard weight category (aluminum models usually around 9–10 kg). Geometry: Rather classic to sportily balanced, often without extreme sloping shapes.
