Derived from an ethnography of working cultures and practices at a bike shop in the North of England, this paper rests on a critical application of social practice theories of literacy (Literacy Studies) in order to explore the complex and heterogeneous literacy practices of cycle technicians. Drawing on a series of vignettes constructed from the ethnographic data, the paper demonstrates the variety of experiences of both formal and informal learning that underpin the literacy practices of the cycle workshop. In addition to providing an account of a qualified and specialist workforce that is under-represented in extant research literature, the paper also provides an exemplar for ethnographic research as a vehicle for exploring literacy practices. The paper also suggests that ongoing debates concerning transferable workplace skills can be enriched through considering situated, contextualised literacy events. The paper concludes by arguing that for cycle technicians, and perhaps other occupations as well, Literacy Studies can generate rich and complex accounts that unpack the textual practices found alongside the occupational expertise and competence being observed.
