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.
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.
This frame supports both 26-inch and 27.5-inch wheels, giving riders and builders the freedom to choose:
Quick, agile handling — perfect for dirt jumps, pump tracks, and tight trails.
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.
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.
