Summary

The Rocky Mountain Instinct is a highly versatile and adjustable trail bike, praised for its ability to handle a wide range of terrains and riding styles. Its adjustable geometry and suspension settings allow riders to fine-tune the bike's performance to their preferences, making it suitable for almost everyone. While it excels in versatility and adjustability, some reviews note limitations in climbing efficiency and high-speed stability on rougher terrains.

Pros
  • Highly adjustable geometry and suspension

  • Versatile performance across various terrains

  • Clean and understated design

  • Solid modern geometry for improved handling

  • Good traction and climbing efficiency

Cons
  • Some models may require frequent pedal strikes

  • Climbing efficiency can be a limitation

  • High-speed stability on rough terrains may be lacking

  • Initial setup may require trial and error

Key Quotes
The Rocky Mountain Instinct is far too capable to be lumped into a category as pedestrian as 'trail bike.'

The Beta Tests: Rocky Mountain Instinct Carbon 70

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.

Highs
  • Incredibly versatile

  • Smart, functional customization

  • Clean, understated look

Lows
  • Ride 9 flip chip requires some trial and error

  • Chainstay-length flip chip adjustment not fine enough

  • Not cheap, but cheaper options abound.

2021 Rocky Mountain Instinct C70 Ride Review

Jul 2021 · Dale Tiessen

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.

Highs
  • Fully XT equipped ride

  • RaceFace Turbine R dropper, Maxxis tires, Ergon grips

  • Frame layup spanning two models reduces cost and improves part availability

  • Ride9 adjustability for geometry and 10mm wheelbase adjustability

  • Predictable climbing and descending suspension

  • Shimano XT shifting and brakes flawless

  • Supports local BC brands

Lows
  • RaceFace AR30 wheelset with basic hubs (DT 370 rear, no-name front) - low spec

  • Fox 36 fork spec'd with Fit4 damper instead of Grip2 at this price point

  • Proprietary derailleur hanger required for short wheelbase setting

  • Cockpit components considered low spec for serious riders

Tested: Rocky Mountain Instinct Carbon 70

Jul 2021

When it came time to ride my hometown trails, I was able to really see how the Instinct stacked up. I’m not one to use clichés, but as I descended the rocky, technical landscape of the Red Hill Special Recreation Management Area near Carbondale, Colorado, all I could think was “Has the trail gotten easier?” The tread, in fact, was more blown out than usual, and ruts were worn deeper around the rocks. The trail hadn’t become easier; the 140 mm travel Instinct just made it feel easier. “This is what they mean by ‘trail-tamer,’” I thought.

If you’ve been following the mag over the years you’ll know that Rocky Mountain’s are a definite favourite amongst our staff here at [R]evo. The reason that we’ve been such big fans of the brand for such a long time comes down to a simple fact; they’re bikes kick arse! Trail performance, speed, technology, reliability and frame aesthetics – Rocky always manage to tick every box and each year their ‘new’ bikes come out with a few little unique details […]

Rocky Mountain Instinct C70 in review - Reined in by its spec

Jun 2021 · Felix Stix

The Rocky Mountain Instinct C70 is one of the hottest bikes of the year. The look and feel of the carbon frame are truly awesome and once you hit the trail, the bike reveals great potential. Unfortunately, this is held back by the spec, which robs the Instinct of its chance of securing the coveted Best in Test title in our big mountain bike group test.

Highs
  • Adjustable geometry and kinematic concept

  • High-quality and well-thought-out frame

  • Conveys safety and fun on every trail downhill

  • Comfortable on long rides

Lows
  • The spec doesn't live up to the potential and rowdy nature of the Instinct

  • Climbing efficiency

  • Heavy paint wear on chainstays and top tube
