Adventure-Tourer Bicycle | Jet Black Surly Bridge Club Sturdy Steel Frame

Adventure-Ready Hybrid Touring Bike
Engineered for cyclists who crave versatility without compromise, the Bridge Club seamlessly transitions between paved highways and rugged backcountry trails. Its robust 4130 CroMoly steel frame—double-butted for strength-to-weight efficiency—supports full pannier/rack systems while maintaining nimble handling on asphalt or loose surfaces.

Key Innovations
