29-inch mountain bike aluminium alloy frame with disc brake mounting, inner cable routing, black green colour options in 410mm or 460mm sizes including integrated headset and five-way construction
29-inch aluminium alloy mountain bike frame with disc brake mounts and internal routing

This mountain bike frame is constructed from aluminium alloy and designed for 29-inch wheels, a popular choice for trail riding due to the improved roll-over capability. It comes prepared for modern disc brake systems, offering consistent stopping power in varied conditions, and uses internal cable routing to keep gear and brake lines protected and out of the way. Available in a black green finish, it provides two sizing options based on seat post length to help achieve a better riding position. The frame's geometry and measurements are outlined to assist with component compatibility during your build.
Features and Construction

The frame's design incorporates several features aimed at modern mountain bike standards and build simplicity. Key dimensions are provided to ensure selected components, such as the forks, seat post, and rear wheel, will fit correctly.
Material and Build
Built from aluminium alloy, this frame aims to offer a resilient platform for off-road use without excessive weight. The construction includes a 34*68mm five-way junction, which forms the main connection between the seat tube, top tube, down tube, and chain stays, contributing to the frame's overall stiffness and handling response. The integrated headset system, sized at 44-55*110mm, is designed to house the bearing assembly directly within the frame for a clean front-end look and reliable steering.
Size and Practical Fit
The frame is offered in a single colour, black green, but with two distinct seat post dimension options: 30.8mm diameter by either 410mm or 460mm length. This allows for adjustment in saddle height to suit different rider leg lengths. The top tube measures 590mm, influencing the reach to the handlebars, while the 385mm rear fork length and 135mm open gear dropout spacing are standard for a 29-inch mountain bike, ensuring compatibility with a wide range of wheelsets and rear derailleurs.
Uses and Placement

As a frameset, this product is the starting point for building a complete mountain bike tailored to your preferences for components like suspension, drivetrain, and cockpit.
Event or Professional Use
The 29-inch wheel platform is commonly used in cross-country and trail mountain biking for its efficiency and obstacle clearance. The frame's disc brake mounts and internal routing are typical of modern performance-oriented bikes, making it suitable for riders looking to assemble a bike for recreational trail riding, fitness, or amateur competition. The aluminium construction provides a dependable base for regular use on forest paths and graded trails.
Everyday Home Use
For the home mechanic or cycling enthusiast, this frame presents a clear project for building a personal bike. The provided specifications, such as the headset size, seat post diameter, and dropout spacing, are essential for sourcing compatible parts. Its standard mountain bike geometry and features make it a straightforward choice for creating a reliable bike for weekend adventures, commuting on rougher paths, or general fitness riding on a variety of surfaces.
Benefits and Buying Value

Purchasing a frame separately allows for a highly customised bicycle and can be a cost-effective way to upgrade or build a bike with specific components.
Reuse and Low Maintenance
Aluminium as a frame material is known for its corrosion resistance and generally requires minimal upkeep beyond cleaning. The internal cable routing helps prolong the life of control cables by shielding them from external abrasion and moisture. As a core part of a bicycle, a well-maintained frame can last for many years and can be refurbished with new components as technology advances or personal preferences change.
Why Choose This Product
This frame offers a practical entry point into the 29-inch wheel size category with contemporary features like disc brake mounts and internal routing. The availability of two seat post length options within the same colourway provides a degree of fit flexibility. Its clearly stated dimensions reduce uncertainty when selecting other parts, making the build process more predictable for anyone assembling their own mountain bike from the frame up.
