130mm/120mm full suspension bike, aluminum frame, Sram 1/11NX drivetrain. This is Salsa’s “any singletrack in the world” bike. Very similar to the Salsa Horsethief, the main difference being that the Pony Rustler has 27.5+ wheels. 29″ wheels work equally as well in this frame. The split pivot suspension does a great job smoothing out the trail.
