2020 Rocky Mountain Slayer Carbon 70 29

The ultimate big mountain platform, the Slayer is meant for riding fast and sending it deep. Designed to be able to pedal to the top of any descent, this bike allows you to shred corners, hit gaps, and ride harder than you ever thought possible.
Add to cart

Whether you're smashing through the roughest trails imaginable or scrubbing lips in the park, the Slayer is built for those who charge. We’ve made it longer and slacker, with better small-bump sensitivity and a more progressive end-stroke. For those who like to fine-tune their ride before they shred, we kept the RIDE-4 adjustment system to allow for further geometry and ride feel customization. Rocky Mountain led the original freeride movement, and the Slayer continues the legacy.

Model Geometry Chart
GEOMETRY - RIDE-4 Adjustment System

The RIDE-4 adjustment system allows riders to quickly fine-tune their geometry with a pair of Allen keys. Four configurations are possible thanks to one rotating chip. This allows for subtle geometry changes with minimal effect on your shock tune.

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.

SUSPENSION - 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.

FRAME CONSTRUCTION - 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 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.
