Rocky Mountain Instinct Carbon 90 (2021)
The Instinct has been designed for epic rides and wide-open singletrack. As our most versatile platform, the Instinct thrives on all types of trails, tackling features with the utmost efficiency and responsiveness.
The Instinct has been the go-to bike for riders looking for a bike that does it all, and our most recent design takes that philosophy to the next level.
The desire to ride faster and harder than ever is universal amongst riders, and the changes we’ve made to our Instinct take that to heart while maintaining peak efficiency.
Updated geometry and frame features mean that the Instinct is versatile and can adapt to meet any demands that you or the trail may have.
Want another opinion? Here's a great review done by NSMB in Canada: 2021 Rocky Mountain Instinct C90 - Long Term Review
Size Specific Suspension
Size Specific Tune ensures that riders of all sizes get the right balance of small-bump compliance, mid-stroke support, and end-stroke progressiveness. Our design team does custom shock tunes based on real world field testing, and adjusts each tune for specific frame sizes.
Ride-9 Adjustable Geometry
The RIDE-9 adjustment system allows riders to quickly fine-tune their geometry and suspension with a pair of Allen keys. Nine configurations are possible thanks to two interlocking chips.
Adjust your RIDE-9 position for geometry before considering suspension effects, or variables like air pressure and shock compression. Make gradual, incremental changes, take notes, and be methodical. Don’t adjust in a hurry before a big ride. Take your time and enjoy the process.
Smoothlink Suspension
Smoothlink suspension is efficient yet supple when you’re on the pedals and across a wide range of gears.
It features a controlled end-stroke and a rate-curve that feels more capable than the travel would suggest.
This four-bar suspension design philosophy is centred on ride characteristics; each bike platform we develop balances variables like anti-squat, axle path, chain growth, rate curve, anti-rise, etc. to achieve the legendary Rocky Mountain ride feel.
Smoothwall Carbon
Smoothwall carbon uses one of the world’s most sophisticated carbon processes to deliver industry leading stiffness-to-weight, ride quality, and durability.
We eliminate excess resin and fibres by using rigid internal moulds instead of traditional air bladders.
We then utilise different types of carbon in specific frame areas to maximise stiffness and impact resistance while minimising overall weight.
