Rocky Mountain Instinct at a glance: longer chainstays, steeper seat angle, longer dropper posts plus adjustable reach and chainstay length.

Rocky Mountain refines the Instinct into their 'holy grail' do-everything trail bike, adding a reach adjust headset for 2024.

Rocky's super-capable trail bike sees updates and refinements to frame features, geo, and suspension kinematics. We've got a first look and details.

The new Instinct has a huge range of geometry options, plus room for snacks. It looks good too.

The Rocky Mountain Instinct C70 stands up against the competition with a flashy paint finish and super variable geometry. How did it fare in our 2022 trail bike group test?
Versatile variable geometry
Efficient suspension generates tons of traction
Excellent all-round qualities
Spec leaves room for improvement
Neither a tool mount nor a storage compartment
Aug 2021 · Travis Engel
This is not a trail bike. When things get real, the Rocky Mountain Instinct can take it. It can be anything. Maybe even a trail bike.
Incredibly versatile
Smart, functional customization
Clean, understated look
Ride 9 flip chip requires some trial and error
Chainstay-length flip chip adjustment not fine enough
Not cheap, but cheaper options abound.

If you’re like me, 2021 left you scrambling for a bike this spring. Having sold off my 2020 Santa Cruz Megatower, feeling it was a bit too much bike for me, I had settled on getting a more trail oriented bike for 2021.
