29-Inch Aluminium Alloy Mountain Bike Frame with Internal Cable Routing and Disc Brake Mounts

This 29-inch mountain bike frame provides the core structure for building a capable off-road bicycle. Fabricated from aluminium alloy, it forms a lightweight yet sturdy foundation suitable for trail riding. A key feature is its preparation for modern disc brakes, with integrated mounts allowing you to fit powerful hydraulic or mechanical systems. The frame employs internal cable routing, which threads brake and gear cables through the frame tubing for a cleaner appearance and reduced exposure to mud and debris. Available in a black green colour finish, it presents a choice for riders building a personalised bike. The package includes a necessary brake bracket to aid in the installation of your chosen braking system.

Features and Construction

The frame's design focuses on modern mountain biking standards and straightforward assembly. Its specifications are defined to ensure compatibility with a range of common components.

Material and Build

The primary construction material is aluminium alloy, selected for its favourable balance of durability and manageable weight in bicycle applications. The frame's geometry includes a 590mm beam length and a rear fork section measuring 385mm in length. Critical interface points are precisely sized: the head tube accommodates a 44-55 x 110mm bearing system, the seat post diameter is 30.8mm, and the rear dropouts are spaced 135mm apart for the wheel hub. The five-way junction, measuring 34 x 68mm, connects the main tubes to form a rigid triangular structure.

Size and Practical Fit

The frame is designed for 29-inch wheels, a standard that offers improved roll-over capability on rough terrain. It is offered in two specific configurations differentiated by the length of the seat tube, noted as 410mm and 460mm rise sizes. This provides an option for riders seeking different standover heights and fit adjustments. The inclusion of a dedicated brake bracket in the contents is a practical touch, ensuring you have the correct hardware to mount your disc brake caliper securely to the frame's provided mounts.

Uses and Placement

This frame is the starting point for creating a mountain bike tailored to trail riding, cross-country, or general off-road use. Its specification supports a build focused on contemporary performance and reliability.

Event or Professional Use

For riders assembling a bike for recreational trail riding or amateur cross-country events, the frame's 29-inch wheel compatibility and disc brake readiness are aligned with common sport-level specifications. The aluminium construction offers a reliable platform that can withstand the demands of varied terrain without the premium cost of more exotic materials. The internal routing helps maintain cable function in muddy conditions, a frequent consideration in off-road cycling.

Everyday Home Use

As a project for a home mechanic or a first custom build, this frame presents a clear set of parameters to work with. The stated dimensions for the head tube, seat post, and rear spacing remove guesswork when sourcing compatible forks, seat posts, and wheels. The black green colour option allows for aesthetic personalisation. Building a complete bike from this frame requires the separate procurement of all other components including wheels, drivetrain, brakes, handlebars, and a saddle.

Benefits and Buying Value

The value of this product lies in its role as a defined, blank canvas for a mountain bike build, offering modern features in a straightforward package.

Reuse and Low Maintenance

As a structural frame, its long-term use is inherent; it serves as the permanent core of the bicycle. The aluminium material is resistant to corrosion and, with proper care, can provide a long service life. The internal cable routing can contribute to lower maintenance by reducing the frequency of cable cleaning or replacement caused by external contamination. The disc brake mounts future-proof the frame, allowing for brake system upgrades without needing a new frame.

Why Choose This Product

This frame is a suitable choice for cyclists or builders seeking a 29-inch aluminium platform with contemporary features like disc brake mounts and internal routing, without unspecified premium claims. Its clearly listed dimensions (head tube: 44-55 x 110mm, beam: 590mm, rear fork: 385mm) facilitate informed component compatibility checks. The availability in two rise sizes (410mm and 460mm) offers a basic fit option, and the included brake bracket ensures you have a essential part to begin assembly. It provides a practical foundation for creating a functional mountain bike based on the supplied specifications.
