    1 Built for the Downhill & All-Mountain Rider

    This frame is engineered for mountain biking and downhill riding. With a robust Alloy 6061 construction and a weight range of 5–10 kg, it delivers the strength and stability needed for aggressive trail riding, jumps, and technical descents. Whether you are building a hardtail or full-suspension setup, this frame provides a solid foundation for high-impact riding.

    2 Premium Alloy 6061 – Strength Meets Durability

    Crafted from heat-treated Aluminum Alloy 6061, this frame offers exceptional rigidity and fatigue resistance. Unlike cheaper alloys, 6061 provides:

    • High tensile strength for withstanding repeated impacts
    • Corrosion resistance for long-term durability in wet or muddy conditions
    • Optimal stiffness for efficient power transfer during climbing and sprinting

    The 5–10 kg weight range ensures the frame is strong enough for downhill abuse yet manageable for climbing.

    3 Wheel Size Flexibility – 26" or 27.5"

    This frame supports both 26-inch and 27.5-inch wheels, giving riders and builders the freedom to choose:

    26"

    Quick, agile handling — perfect for dirt jumps, pump tracks, and tight trails.

    27.5"

    Best balance of rollover capability and acceleration — ideal for all-mountain and enduro riding.

    Both sizes are optimized for proper geometry and clearance, ensuring the bike handles as intended.

    4 True Suspension Design – Engineered for Control

    As a dedicated suspension mountain bike frame, it is designed to work seamlessly with modern suspension systems:

    • Reinforced head tube and down tube for fork and shock compatibility
    • Optimized linkage points (on full-suspension models) for progressive suspension feel
    • Ample tire clearance for 2.3" to 2.6" tires, even in muddy conditions

    The frame geometry is tuned for aggressive descending while maintaining climbing efficiency.
