2020 Rocky Mountain Instinct A70 BC Edition

Born in BC, we've turned the Instinct into an aggressive trail monster.

Designed with an optimized single-position link, ultra-aggressive geometry, and a long stroke shock that provides 155mm of rear travel, we’ve kitted out the Instinct BC with wide bars, big tires, ultra-stiff wheels, and more capable suspension. It smashes all-mountain lines, rails corners, and plows over everything in sight while displaying all the climbing efficiency that makes the Instinct a crowd favourite.

SUSPENSION - Size Specific Tune

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.


FORM™ tubesets utilize premium materials to meet our strict requirements. Each FORM™ tube that we create is engineered for its specific purpose within the frame, ensuring optimized strength, weight, and ride quality.


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 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 fibers by using rigid internal molds instead of traditional air bladders. We then utilize different types of carbon in specific frame areas to maximize stiffness and impact resistance while minimizing overall weight.
