Why the Rocky Mountain Instinct?
The Rocky Mountain Instinct is a versatile trail bike designed to handle everything from technical climbs to aggressive descents. It features 150mm of front and 140mm of rear travel, making it perfect for tackling a variety of terrains. The Instinct is available with either 29-inch or 27.5-inch wheels, and the adjustable geometry allows riders to fine-tune the bike’s handling using Rocky Mountain’s RIDE-4™ adjustment system and a two-position axle dropout. This gives riders flexibility to adapt to different riding styles and conditions.
Engineered for adventure, the Instinct features refined geometry, including a steeper seat tube angle, longer chainstays, and customized tuning for each frame size to ensure small-bump compliance and overall ride quality. It’s lightweight, durable, and highly adaptable, making it a go-to choice for riders looking for a do-it-all trail bike. Whether you're on a singletrack or a multi-day bike-packing trip, the Instinct is built to handle it all.

Frame Sizing
The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
