29-inch mountain bike frame crafted from aluminium alloy with integrated disc brake mounts, internal cable routing, and a choice of 410mm or 460mm seat post length in a black green colour scheme
29-inch aluminium mountain bike frame with disc brake mounts and internal cable routing

This mountain bike frame is constructed from aluminium alloy, forming the central structure for building a bike around 29-inch wheels. It is designed with integrated mounts for modern disc brake systems, offering the potential for consistent braking performance in various conditions. The frame features internal cable routing, which guides gear and brake cables through the inside of the frame tubes for a streamlined appearance and reduced exposure to dirt and moisture. Available in a black green colour, it comes with a choice of seat post length to accommodate different rider setups, making it a practical base for a custom or upgrade bike project.
Features and Construction

This frame is built with specific dimensions and features tailored for mountain biking. Its construction focuses on providing a reliable platform for a 29-inch wheel bike, with details that support modern component standards.
Material and Build
The primary material is aluminium alloy, chosen for its favourable strength-to-weight ratio, which contributes to a lightweight yet rigid frame. The construction includes a 34 * 68mm bottom bracket shell and a head tube sized at 44-55 * 110mm, which are standard dimensions for compatible components. The internal cable routing system, referred to as 'innerline', is integrated into the frame design to house cables neatly.
Size and Practical Fit
The frame's top tube measures 590mm in length, influencing the bike's reach and cockpit feel. A key fitting option is the seat post, offered in two lengths: 410mm and 460mm, both with a 30.8mm diameter. This choice allows for adjustment to suit a range of rider heights and preferred saddle positions. The rear of the frame has a fork length of 385mm and uses a 135mm dropout spacing, which is a common standard for mountain bike rear hubs.
Uses and Placement

This frame is intended as the starting point for a mountain bike build. Its specifications make it suitable for various off-road riding applications, from trail riding to more general cross-country use.
Event or Professional Use
For riders building a bike for organised events or regular trail riding, the 29-inch wheel size and disc brake compatibility are significant advantages. The large wheel diameter can help roll over obstacles more easily, while the prepared disc brake mounts allow for the fitment of powerful braking systems essential for technical descents and variable conditions. The rigid aluminium frame provides efficient power transfer for climbing.
Everyday Home Use
As a project for a home mechanic or an upgrade for an existing bike, this frame offers a clear foundation. The inclusion of a brake bracket in the package aids the installation process. The black green colour provides a neutral, understated look that can be paired with various component colours. Its standard dimensions mean a wide range of common aftermarket parts will be compatible, simplifying the sourcing process for handlebars, stems, seat posts, and drivetrain components.
Benefits and Buying Value

The value of this frame lies in its role as a core component for a custom build. It offers a way to create a bike tailored to specific preferences or to replace a damaged frame on an existing bike.
Reuse and Low Maintenance
Aluminium as a material is generally resistant to corrosion and requires minimal maintenance beyond keeping it clean. The internal routing helps protect cables, which may contribute to longer cable life and smoother operation between replacements. The frame itself, being a structural item, is a long-lasting component provided it is used within its design limits and not subjected to impact damage.
Why Choose This Product
This frame is a suitable choice for anyone needing a 29-inch mountain bike frame that is ready for disc brakes and features internal cable routing. Its stated aluminium construction offers a known performance characteristic, and the provided exact dimensions allow for precise component compatibility checks. The option of two seat post lengths adds a degree of fit customisation from the outset, which is a practical consideration for achieving a comfortable riding position.
