29-inch mountain bike aluminium alloy frame with disc brake compatible inner line routing for adult trail cycling in black green colour with two seat post riser size options of 410mm or 460mm
29-inch aluminium alloy mountain bike frame with disc brake compatibility and inner line routing

This 29-inch aluminium alloy mountain bike frame serves as the foundation for building a capable adult trail bicycle. Designed specifically for off-road and trail cycling applications, it provides the structural base for a complete mountain bike build. The aluminium alloy construction offers a balance of lightweight performance and durability, while the 29-inch wheel size specification ensures compatibility with modern mountain bike components. With inner line routing for cleaner cable management and disc brake compatibility for reliable stopping power, this frame accommodates riders seeking to construct or upgrade their trail bicycle.
Features and Construction

This mountain bike frame incorporates several design elements aimed at trail performance and practical assembly. The aluminium alloy material provides the structural base, while specific dimensional specifications ensure compatibility with standard mountain bike components.
Material and Build
The frame is constructed from aluminium alloy, a material commonly used in bicycle frames for its favourable strength-to-weight ratio. This construction provides a rigid platform for trail riding while maintaining manageable weight. The inner line routing system allows cables to run internally through the frame, reducing external exposure to trail debris and creating cleaner aesthetic lines. The frame is designed to be compatible with disc brake systems, which offer consistent braking performance in varied trail conditions compared to rim brake alternatives.
Size and Practical Fit
The 29-inch wheel size specification indicates compatibility with modern mountain bike wheels, providing improved obstacle rollover capability on trails. The frame features a 44-55 * 110mm head tube size that accommodates standard suspension forks and headset components. With a beam length of 590mm, it provides appropriate reach for adult riders. The 34 * 68mm Five-Way dimension and 385mm rear fork length create frame geometry suited to trail riding positions and handling characteristics.
Uses and Placement

This frame serves as the central component in building a complete mountain bike for various cycling applications. Its specifications make it suitable for both recreational trail riding and more dedicated off-road cycling pursuits.
Event or Professional Use
For trail riders and mountain biking enthusiasts, this frame provides a foundation for building a capable off-road bicycle. The 29-inch wheel compatibility offers advantages on technical trails where obstacle clearance matters, while the aluminium alloy construction provides responsive handling characteristics. The disc brake compatibility ensures reliable stopping power during descents and in variable trail conditions. The inner line routing reduces cable snagging on narrow trails where vegetation or obstacles might catch externally routed cables.
Everyday Home Use
For home mechanics and cycling enthusiasts building their own mountain bike, this frame offers standard specifications that simplify component selection. The 135mm open gear dimension ensures compatibility with a wide range of rear wheel hubs, while the head tube size accommodates commonly available suspension forks. The availability of two seat post riser sizes (410mm or 460mm) allows adjustment for different rider heights without requiring aftermarket modifications. The black green colour provides a neutral base for building a personalised bicycle.
Benefits and Buying Value

This mountain bike frame provides practical advantages for riders building or upgrading their trail bicycle. Its design focuses on compatibility with modern mountain bike standards and clean cable management solutions.
Reuse and Low Maintenance
The aluminium alloy construction requires minimal specialised maintenance beyond standard bicycle care practices. The inner line routing protects cables from external elements that might accelerate wear, potentially extending cable lifespan compared to externally routed systems. The disc brake compatibility allows riders to utilise modern braking systems that typically require less frequent adjustment than some rim brake alternatives in muddy or wet trail conditions.
Why Choose This Product
