29 inch Mountain Bike Frame with aluminium alloy construction, disc brake compatibility, and internal cable routing. Available in black green with 410mm and 460mm head tube sizes.
29 Inch Aluminium Mountain Bike Frame with Internal Cable Routing and Disc Brake Compatibility

This mountain bike frame provides a core structural component for building or refurbishing a 29 inch wheel mountain bike. Manufactured from aluminium alloy, it offers a practical foundation for riders seeking to create a modern off-road bicycle with the benefits of internal cable routing and disc brake compatibility. Available in two head tube size variations (410mm and 460mm), both in a black green finish, this frame accommodates standard 135mm rear hubs and features precise tubing dimensions for predictable handling characteristics.
Features and Construction

The frame incorporates several design elements common to contemporary mountain bike engineering. Its construction focuses on providing a reliable platform for component attachment while maintaining compatibility with modern standards.
Material and Build
Constructed from aluminium alloy, this frame utilises a material known for its favourable strength-to-weight ratio in bicycle applications. The alloy construction contributes to overall bicycle weight reduction compared to steel alternatives, which can be beneficial for climbing and acceleration on trails. The frame features internal cable routing, a design that passes control cables through the frame tubing rather than along the exterior, resulting in cleaner aesthetics and reduced vulnerability to snagging on trailside vegetation.
Size and Practical Fit
The frame is designed specifically for 29 inch wheels, a common standard for modern mountain bikes that provides improved rollover capability over obstacles. Two head tube length options are available: 410mm and 460mm, which correspond to the riser dimensions of 30.8*410mm and 30.8*460mm respectively. These variations allow for some adjustment in front-end height and handlebar positioning. Other critical dimensions include a 590mm beam length, a 34 * 68mm five-way junction, a 385mm rear fork length, and standard 135mm rear dropout spacing for hub compatibility.
Uses and Placement

This frame serves as the central component in building a complete mountain bike. Its specifications make it suitable for various off-road cycling applications, from trail riding to general recreational use.
Event or Professional Use
For riders building a bike for regular trail use or amateur competition, the frame's disc brake compatibility ensures accommodation of powerful hydraulic or mechanical disc braking systems, which provide consistent performance in varied weather conditions. The 29 inch wheel size is widely used in cross-country and trail mountain biking disciplines. The aluminium construction offers a balance of durability and weight that suits extended riding sessions where fatigue management is a consideration.
Everyday Home Use
For the home mechanic or enthusiast undertaking a build project, this frame provides a straightforward starting point with clearly stated dimensions for component selection. The internal routing, while requiring careful cable installation, results in a tidy finished appearance for a bike used on local trails or forest paths. The black green colour option offers a subdued aesthetic that doesn't show trail dust as readily as lighter colours.
Benefits and Buying Value

Choosing this frame involves considering its role within a complete bicycle system. Its value derives from its material specifications, compatibility standards, and the flexibility it offers during the build process.
Reuse and Low Maintenance
As a structural frame, this component forms the long-term foundation of a bicycle. Aluminium frames generally require minimal ongoing maintenance beyond keeping pivot areas clean and checking for damage after significant impacts. The internal routing design protects cables from external abrasion, potentially extending their service life. The frame itself, if undamaged, can be reused with updated components over multiple upgrade cycles.
Why Choose This Product
This frame is selected for its adherence to modern mountain bike standards: 29 inch wheels, disc brake mounts, and internal routing. The provision of two head tube sizes increases the likelihood of achieving a suitable fit. For those replacing a damaged frame or building a bike from new components, the clearly specified dimensions (head tube: 44-55 * 110mm, beam: 590mm, etc.) allow for precise compatibility checking with existing parts. It represents a functional, specification-led choice rather than one based on brand prestige or cosmetic appeal.
