    Marin Mount Vision 8 - 2021

    The all-new Mount Vision from Marin embodies the true spirit of mountain bikes, designed to make the climbs effortless and the descents mind-blowing. The Mount Vision is equipped with 150mm of travel front and rear, a perfect balance of suspension and playfulness. The rear suspension features the Naild R3ACT – 2 Play system, which brings riders the best in rear suspension with size specific kinematics and ground tracing performance. The Mount Vision is the new benchmark for 27.5” trail bikes.



    WHEEL SIZE: 27.5"
    SUSPENSION: 150mm/150mm

    COLOR: Gloss Carbon/Charcoal/Cyan

    The most high-end products require the most detailed approach. The Mount Vision features two separate kinematics for the S/M and L/XL sizes to make sure the suspension and ride quality is the best that money and technology can offer for most every size rider.

    "I’m battling to describe how good this bike rides without swearing but will politely say; it’s f#@king sick! Get near one for a test ride or borrow a mates as soon as you can, you will not regret it." —


      The revolutionary Naild R3ACT — 2 Play Suspension gives the Marin Mount Vision a true performance advantage over traditional systems. By isolating the rider’s mass from acceleration forces, a new benchmark in pedaling efficiency and bump absorption is achieved. What this means for the rider is no lockouts, no loss of power transfer, and the best traction you have ever had.

      At the heart of the Naild R3ACT – 2 Play system, Ground Tracing kinematics allows the rear wheel to follow the contours of the trail, providing the rider improved wheel contact and loading with the ground as the bike moves over bumps. Increasing the time that the wheel is on the ground not only guarantees maximum control over terrain, it also increases efficiency by allowing the bike to recover energy off the backside of bumps.

      The Mount Vision was designed using anthropometric data to define rider position and center of gravity. From this data, Marin worked with Naild to develop two separate kinematics, one for sizes small and medium and one for sizes large and extra-large.

      The unidirectional carbon fiber frame utilizes the latest in high modulus carbon fiber technology, materials, and layup for the lightest and strongest frame possible.
