Rob Roberson is an enigma in the handmade bicycle world. Some would consider him “the greatest known unknown bike fabricator” of the American frame building movement. His career, which spans nearly 50 years, puts him among a very small pedigree of builders that have both mass-production experience and have also built custom bikes under their own name without giving up the ghost. Yet, with such a significant trajectory, Rob has remained largely unknown. Over the next few weeks, we’ll be featuring bikes made by Rob and the stories about them. Today, however, Zach Small and Josh Weinberg are honored to introduce you to Rob Roberson.
