AM MTB Frame (Travel: 130-140mm)

MK’s All Mountain MTB Frame is designed for riders who want a single bike to handle climbs, technical trails, and moderate descents within one ride. Rather than focusing on a single performance extreme, the frame follows a balanced design approach that emphasizes control, adaptability, and all-around trail capability, making it well-suited for MTB frame ODM projects targeting versatile mountain riding.


Mk’s All Mountain MTB Frame is developed for mixed mountain riding where terrain, elevation, and trail conditions vary throughout the ride. The key frame characteristics below explain how the frame is designed to balance efficiency, control, and reliability across diverse riding scenarios.

 

  • Geometry Tuned for Climbing and Descending

    The frame geometry is designed to support confident handling on descents while remaining comfortable and composed during climbs. This tuning helps riders stay in control as the ride shifts between uphill, flat, and downhill sections, without the bike feeling overly aggressive in either direction.

  • Moderate Suspension Travel for Trail Impact Control

    With a suspension travel range of 130-140mm, the frame is set up to absorb common trail impacts such as roots, rocks, and uneven surfaces. This level of travel provides enough cushioning for technical trails without introducing the excess movement or weight associated with longer-travel gravity setups.

  • Pedaling Support for Long, Mixed Rides

    All mountain riding often involves extended periods of pedaling between technical sections. The frame is engineered to support steady power transfer while allowing the suspension to remain active over trail irregularities, helping riders maintain momentum across longer, mixed-terrain rides.

  • Flexible Platform for All Mountain Builds

    The frame platform supports 27.5”, 29”, and mixed wheel configurations, along with multiple drivetrain and component standards, allowing brands to tailor the frame to different all mountain riding preferences and markets. As an MTB frame ODM platform, it offers the flexibility needed to develop balanced all mountain models while maintaining a consistent core frame design.

MK’s All Mountain MTB Frame delivers a balanced foundation for riders who want versatility across climbs, trails, and descents. Contact us to discuss configuration options or project requirements.
