Surly Sorceress Frame Steel trail magic The Surly Sorceress is a modern trail hardtail built to thrive where things get steep, loose, and rowdy. Purpose-built from the famous Surly Natch chromoly steel, with a double-butted main triangle and trumpet-flared tubes, gives the Sorceress a lively, composed ride quality that synthetic materials rarely replicate. The geometry is unambiguously modern: slack head angle, steep seat tube, long front center, and maximized standover for riders from 4'9" to 6'6". The patent-pending DUH dropout system lets you run SRAM UDH, Full-Mount drivetrain, or single-speed, making the Sorceress genuinely versatile without compromise.
