The Instinct has been the go-to bike for riders looking for a bike that does it all, and Rocky Mountain's most recent design takes that philosophy to the next level. The desire to ride faster and harder than ever is universal amongst riders, and the changes they've made to the Instinct take that to heart while maintaining peak efficiency. Updated geometry and frame features mean that the Instinct is versatile and can be adapted to meet any demands that you or the trail may have. 

With 140-millimeters of rear travel, the Instinct is designed for efficient and versatile trail riding, which is why Rocky also offers six frame sizes,  including size small available in two distinct frames to accommodate either 27.5" or 29" wheels (XS, S: 27.5"; S, M, L, XL: 29").
