The Rocky Mountain Instinct Carbon 70 is a multipurpose trail bike designed to tackle both rapid descents and lengthy ascents. The bike's carbon frame provides a sturdy, responsive platform, and its well-balanced suspension system maintains the bike's composure and support under pressure. Modern trail geometry is suited to a variety of trail systems because it offers stability at speed without compromising agility in tighter portions. The Instinct Carbon 70 is a genuine do-it-all trail bike that combines all-day capability, confident descent, and climbing efficiency into a sophisticated, performance-driven design.

• Premium Carbon Frame: Constructed from Rocky Mountain's SMOOTHWALL™ Carbon, the frame offers an excellent strength-to-weight ratio, full-sealed cartridge bearings for longevity, and internal cable routing for a clean look .

• RIDE-9™ Adjustable Geometry: This system uses a flip-chip at the suspension linkage with nine possible configurations. It allows riders to fine-tune the head tube and seat tube angles, as well as the bottom bracket height, to perfectly match the terrain or personal preference .

• Two-Position Axle: The rear axle features a 2-position flip-chip that adjusts the chainstay length. This allows you to change the bike's handling character—shorter for a more playful, agile feel, or longer for greater stability at high speeds .

• Versatile Suspension Platform: The bike features 140mm of rear travel paired with a 150mm fork, providing a supple and efficient suspension setup. The shock features a size-specific tune to ensure optimal performance for lighter riders on the XS frame .

• Size-Specific Design: Rocky Mountain uses a "RIDE-9" system that includes size-specific tunes for suspension kinematics, ensuring that smaller riders on an XS frame get the same balanced and capable ride as taller riders .

• Mixed Wheel Compatibility: The Instinct is designed to be run as either a 29er or a 27.5" bike, with the XS and SM frames optimized for 27.5" wheels, while MD-XL frames roll on 29" wheels
