Commodity items may be singularized and revalorized in markets for second-hand goods. The market for singular goods, often cultural or aesthetic items, depends upon collective assessments of value, where the nature of value is embedded in the cultural community. Exiting studies have concentrated on the work of experts and practitioners within markets as they construct goods as valuable. As research begins to see valuation as a nexus of social relations, so it becomes important to study how valuation practices organize markets that span countries and socio-economic categories. We examine the valorization practices of second-hand bicycle traders in Hungary. These market intermediaries salvage obsolete discarded steel bicycles and reconstitute them into fashionable vintage bicycles: sought-after subcultural fashion accessories and collectors’ prized items. We propose a theory of value bricolage to describe the process of constructing value through the skilful combination of matters at hand, material, social and imaginary: scrap frames, spare parts, online resources, fan websites, and valuation communities.
