Surly: Function-focused steel bikes from Minnesota

Surly was founded in 1998 in Bloomington, Minnesota, and focuses on building versatile steel bikes.

Their design philosophy is based on two central concepts: "Steel is Real" and “Fatties Fit Fine”. This means they exclusively use 4130 chromoly steel for its mechanical properties and prioritize generous tire clearance across all their models. This makes their frames suitable for long-distance cycling and riding on varied terrain, where comfort and load capacity matter. One of their best-known models is the Steamroller, a stripped-down frame for fixed gear and single speed that has become a standard in the segment.
