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.

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.

2021 Rocky Mountain Instinct

Mar 2021

The Instinct is a trail bike with teeth, sporting 140mm of rear wheel travel paired with a 150mm fork. For most riders in most places that don't intend to race XC or Enduro (and even some that do want to race), this is your bike. With geo that is progressive without alienating a swath of riders' body shapes, the Instinct's intentions are clear: pedaling efficiency for long rides in a variety of terrain, and plenty of capability for taking on technical sections of trail. If your priorities are close to 50/50 for pedaling efficiency and technical prowess (give or take 10-20%), Instinct is your jam.
