MTB Frames

Built for Real Terrain

LightCarbon Platform Approach

LightCarbon frames are developed as OEM platforms, focusing on structural efficiency, material layup consistency and controlled manufacturing processes rather than visual branding or mass-market positioning.

For Cyclingdragon, this approach aligns with how we evaluate MTB frames: by geometry intent, stiffness balance, and long-term durability under real riding conditions.

LightCarbon’s MTB frames are tested according to EN standards, with additional safety margins, providing a transparent and well-defined engineering baseline across multiple riding categories.

Instead of relying on certification labels alone, the focus is placed on repeatable production quality, structural validation, and compatibility with modern MTB standards and components.

When a frame platform demonstrates consistent engineering logic and proven manufacturing discipline, it becomes a viable foundation for a custom MTB build — regardless of market trends or branding.

Evaluation criteria are applied with respect to the intended riding segment, ensuring that each frame is assessed within its real-world use case.

Evaluation Focus

  • Carbon layup consistency and structural balance
  • Geometry design aligned with intended riding use
  • Manufacturing repeatability and quality control
  • Compliance with current MTB component standards
  • Segment-specific evaluation (XC, Trail, Hardtail, Downhill)

Engineering is not about logos. It is about structures that hold up over time.
