29-inch Mountain Bike Frame in aluminium alloy with disc brake compatibility, innerline routing, 135mm open gear spacing, and black-green colour finish in two riser sizes for MTB builds
29-Inch Aluminium Mountain Bike Frame for Disc Brakes and Innerline Routing

This 29-inch mountain bike frame serves as the core component for building a capable off-road bicycle. Manufactured from aluminium alloy, it is designed to accommodate modern disc brake systems and features internal cable routing for a clean aesthetic and reduced cable wear. The frame's geometry and sizing, including its two available riser options, make it a practical choice for riders looking to assemble a hardtail mountain bike suited to trail centres, forest paths, and general off-road use. It arrives with a brake bracket included, ready for component installation.
Features and Construction

This frame is built with specific features that define its purpose and compatibility within a mountain bike build. The construction focuses on integrating modern standards and providing a reliable platform for other components.
Material and Build
The primary material is aluminium alloy, a standard choice for bicycle frames that provides a favourable combination of durability, stiffness, and manageable weight for mountain biking. The frame is designed with disc brake mounts, allowing the use of powerful hydraulic or mechanical disc brakes essential for controlled stopping in wet or muddy conditions. The inclusion of a brake bracket in the package aids in the correct alignment and fitting of the rear brake caliper.
Size and Practical Fit
The frame is built for 29-inch wheels, which are popular for their ability to maintain momentum and roll over obstacles more easily than smaller wheel sizes. Key dimensions that influence bike fit and handling include a 590mm beam length and a 385mm rear fork length. A notable feature is the availability of two riser sizes: 30.8mm in diameter with lengths of 410mm and 460mm. This allows the rider or builder to select the taller riser for a more upright riding position or the shorter one for a lower, more aggressive stance.
Uses and Placement

This frame is intended as a starting point for creating a functional mountain bike. Its design dictates the type of riding it is best suited for and influences how the completed bike will perform.
Event or Professional Use
As a core component, this frame could be used by cycling enthusiasts or workshop mechanics to build a custom hardtail mountain bike for personal use, club riding, or entry-level trail riding. Its specifications, such as the 135mm open gear spacing, align with common standards, making it compatible with a wide range of groupsets and wheels from various manufacturers. The precise frame dimensions provide a predictable geometry for handling on varied terrain.
Everyday Home Use
For the home mechanic or cycling hobbyist, this frame represents a project base. The innerline routing simplifies the final appearance of the built bike and helps protect control cables from dirt and debris. The black-green colour finish offers a subdued, practical look. Building a bike from this frame requires sourcing additional components like wheels, a fork, a drivetrain, brakes, and finishing kit, making it a project for those with some technical knowledge or access to assembly services.
Benefits and Buying Value

Choosing a separate frame offers specific advantages over purchasing a complete bike, particularly for those with specific component preferences or upgrade plans.
Reuse and Low Maintenance
A key benefit of a frame-based build is the potential for longevity and upgradability. Should other components like wheels or the drivetrain wear out or become outdated, they can be replaced independently while retaining the core frame. The aluminium construction is resistant to rust and, with proper care, can serve as a long-term foundation. The internal routing also contributes to lower maintenance by keeping cables cleaner and less prone to snagging.
Why Choose This Product
This frame is a practical choice for anyone needing a 29-inch hardtail platform that supports disc brakes and tidy cable management. Its value lies in its adherence to common mountain bike standards, which ensures broad parts compatibility. The option of two riser sizes provides a degree of customisation for rider comfort from the outset. It is a straightforward, no-frills frame suited to creating a reliable mountain bike for recreational trail use.
