Salsa designed and built the Horsethief SX 12-speed to be your versatile trail 29er, your do-it-all full-suspension fun machine. They started with a double- and triple-butted, heat-treated 6066-T6 aluminum frame to provide stiffness and durability. Then they gave it 140 mm front and 120 mm rear travel, their excellent Split Pivot suspension system, and all-around geometry for tackling lines in all types of terrain. SRAM SX EAGLE 12-speed drivetrain is smooth and reliable wherever you may roam.
