American custom frame builders are mostly one- and two-person shops that measure the rider, design the frame around that rider, and build it by hand. Many also make matching forks, stems and racks, several paint their own frames, and a few teach framebuilding classes.

Builders who work mainly in one material have their own pages: steel, titanium and carbon fiber. The builders listed on this page work in more than one material, such as steel and titanium, carbon mixed with steel or titanium, or aluminum and scandium, or build each frame in whatever material suits the rider. Builders known for one kind of bike, such as touring, tandem or cargo bikes, are listed under that type.

Ordering a custom frame

Expect a fitting or a set of measurements, a conversation about how and where you ride, and a wait while the builder works through earlier orders. Many one-person shops keep a waiting list, and some close their order books for a time, so check the builder's site before you plan around a date. A builder close to home makes an in-person fitting easier.
