Surly makes functional bikes that do what they’re designed to do. They don’t build one-trick ponies; they help Surly riders embrace options. Their bikes are built to last a long time.  Their ‘Natch!’ tubesets are 100% proprietary 4130 CroMoly. This means every model has a unique tubeset designed by their engineers to match the intended use and loading characteristics of the bike. In addition, sizes within each model have tubesets scaled to preserve optimum butting profiles.

A few final words about Surly values: UTILITY. VERSATILITY. DURABILITY.
