29-inch aluminium alloy mountain bike frame with inner line routing and disc brake compatibility

Upgrading or replacing the core structure of your mountain bike starts with a compatible and well-built frame. This 29-inch aluminium alloy frame is engineered to serve as that essential foundation, designed specifically for adult-sized mountain bikes that tackle trails and rough terrain. Its stated geometry and construction details provide a clear blueprint for builders, focusing on key dimensions like the 590mm beam length and 135mm rear spacing to ensure fit with standard components. The inclusion of inner line routing offers a contemporary solution for managing brake and gear cables neatly within the frame, contributing to a cleaner overall bike aesthetic and potentially reduced cable wear.

Features and Construction

This frame’s design centres on providing a reliable platform for a mountain bike build, with several concrete specifications defining its use case and compatibility.

Material and Build

The frame is fabricated from aluminium alloy, a material commonly chosen for bicycle frames due to its favourable strength-to-weight ratio. This construction provides a rigid base that can handle the stresses of off-road cycling without excessive flex. The frame is finished in a black green colour, and its build includes the practical feature of inner line routing. This design allows cables to be run inside the frame tubes, which can help protect them from external damage and gives the finished bike a streamlined, professional look.

Size and Practical Fit

Critical to any frame purchase is ensuring it fits both the rider and the other bicycle parts. This frame is built for 29-inch wheels, the larger diameter standard that offers improved rollover capability on trails. Key dimensional data includes a head tube sized at 44-55mm by 110mm, which must match your chosen fork’s steerer tube. The beam length is 590mm, influencing the bike’s reach and rider position. You have a choice between two riser sizes: 30.8mm by 410mm or 30.8mm by 460mm, allowing some adjustment for handlebar height and cockpit setup.

Uses and Placement

This component is not a complete bicycle but a core part around which a bike is built, dictating its intended use and the type of riding it will support best.

Event or Professional Use

For the bike builder, mechanic, or enthusiast assembling a bike for specific purposes, this frame serves as the starting point. Its 29-inch wheel size, 135mm open rear spacing, and disc brake compatibility make it suitable for building a modern hardtail or rigid mountain bike meant for trail riding, cross-country, or general off-road use. The precise geometry, including the 385mm rear fork length and 34 x 68mm five-way junction, contributes to the bike’s handling characteristics, making it a considered choice for riders who understand how frame dimensions affect ride quality.

Everyday Home Use

For a rider looking to replace a damaged frame on an existing bike or undertake a custom build project at home, this frame provides the necessary specifications to check against current components. Ensuring your existing wheelset fits the 135mm rear spacing and that your fork matches the head tube dimensions is essential. The clear sizing information allows for informed purchasing, reducing the risk of buying incompatible parts for a DIY repair or upgrade project.

Benefits and Buying Value

The value of this frame lies in its role as a foundational component and the practicality offered by its specific, stated features.

Reuse and Low Maintenance

As a central bicycle component, a well-chosen frame can be the basis for multiple builds or upgrades over time. The use of aluminium alloy is associated with a material that does not require the specific anti-corrosion treatments of steel, though general care is still needed. The inner line routing can contribute to lower maintenance by keeping cables less exposed to mud and debris, potentially extending their service life. The frame itself, as a structural element, is designed for long-term use when paired with correctly maintained components.

Why Choose This Product

You would select this frame if you require a 29-inch aluminium mountain bike frame with confirmed dimensions for a build or repair. Its value is in the concrete data provided: the exact head tube size, beam length, rear spacing, and the option for two riser heights. It offers a solution for riders who need a specific frame size and style (black green colour, inner routing) and whose component compatibility aligns with its 135mm rear spacing and disc brake mount design. It is a functional part for a functional purpose, without unsupported claims about performance beyond its stated construction.
