Darrell McCulloch started working as a bicycle mechanic and apprentice aged 16, under framebuilder Eric Hendren at Hoffy Cycles in Brisbane. Ten years later, in 1989, Llewellyn Custom Bicycles opened its doors. In addition to his workshop time, McCulloch has brought 15 years of his own bicycle racing experience in Australia and Europe to his business, as well as six years working for the elite Australian Institute of Sport as a fabricator and mechanic. Contract work for the Australian national team has taken him to 23 different countries at many of the world's greatest cycling events. His preferred material is steel and he makes custom bikes for a range of purposes using this material. In this video he presents a randonneur with integrated lighting system and a neat bag attaching method.
