Frame Geometry


This model mtb hardtail frame use high-Performance Wheel Hub – 135x9mm / 142x12mm Engineered for modern trail and enduro applications, this hub accommodates both standard 135x9mm quick-release and contemporary 142x12mm thru-axle standards. The dual-compatibility design eliminates frame-specific constraints, allowing seamless integration across multiple builds. Precision-machined internals and robust bearing surfaces support sustained high-load riding while maintaining low rotational resistance. Whether upgrading existing wheels or building custom sets, this hub's versatile axle options provide the flexibility serious riders demand.

Internal Cable Routing Frame Design This frame mountain bike features fully integrated internal cable routing that conceals hydraulic lines, shift cables, and brake hoses within the tube structure. The design eliminates external cable clutter while protecting routing from trail debris and weather exposure, extending component lifespan and maintaining a clean aesthetic. Precision-machined cable ports and guides ensure smooth cable movement without binding or friction losses during shifts and braking inputs. The internal architecture accommodates both mechanical and electronic drivetrain systems, offering flexibility for current builds and future upgrades. Maintenance access points are strategically positioned for straightforward cable replacement and adjustment without frame disassembly. This engineering approach combines performance benefits—reduced aerodynamic drag and improved mud shedding—with practical durability advantages that appeal to serious cross-country and endurance riders.
