Key Quotes
Is it a backcountry scree-slope raider? Is it a big-wheel play bike, a slack-angled couch, a relaxed-fit trail carver, a long-legged marathon racer? Yes.

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

Bike Review | 2021 Rocky Mountain Instinct Carbon 70

Mar 2021 · Spencer Astra

I was excited to test Rocky Mountain Bicycle’s new Instinct Carbon 70 model, as it sits squarely in my favorite category of suspension travel. It’s not a sloppy, big-travel brawler, nor is it a wrist-slamming short-travel whip. With 140 millimeters of rear-wheel travel, the new Instinct strikes some perfect middle ground, providing just the right amount of squish to scoot one around smoothly and precisely. Adding to the bike’s versatility is the highly adjustable RIDE-9 system, which allows riders to quickly fine-tune their geometry and rear suspension with a pair of Allen keys. With nine configurations to choose from, the range of geometry helps make the bike more suitable to a broad spectrum of terrain and riding conditions. Even in the slackest setting, the Instinct climbs extremely well, thanks to a reasonably forward seated position. The leverage curve of the rear suspension is ultra-supple off the top, but it ramps up quickly to keep the bike manageable during out-of-the-saddle bursts of pedaling. The adjustable chainstay length of 437 millimeters or 448 millimeters should add to the Instinct’s versatility, but I opted to keep the bike in the 437-millimeter mode for the duration of my testing period, as it already felt long and stable enough for my taste.
