Custom Single Speed

I built this frame in a framebuilding class at Artisan’s Asylum, taught by the esteemed Paul Carson of Paul Carson Designs. It was TIG welded from 4130 steel and then powdercoated battleship gray (thanks Paul!). The fork is my own design, more or less, again with plenty of help from Paul.

I built the wheels and everything else myself. Skills I learned were bicycle framebuilding and basic frame design considerations, how to use a mini-lathe, brazing, and vinyl cutting.

This bike is quite fast — it has minimal components, so it’s quite light, and the high pressure tires have very little rolling resistance. It’s not particularly useful for commuting, but it’s great for sprints and aerobic exercise.
