29-inch aluminium alloy mountain bike frame with disc brake mount and internal routing

This mountain bicycle frame is constructed from aluminium alloy, offering a robust and relatively lightweight base for building a trail-ready 29er bike. Designed for the popular 29-inch wheel size, it provides a stable rolling platform suited to various off-road conditions. A key feature is its internal cable routing, which guides brake and gear lines through the frame for a sleeker aesthetic and reduced risk of cable damage from external impacts. The frame is prepared for modern disc brakes via its dedicated mount, allowing for consistent stopping power in wet or muddy environments. It is available in a black green finish and comes with a choice of two seatpost lengths, providing flexibility for different rider builds and riding styles.

Features and Construction

This frame's design incorporates several standard mountain bike specifications to ensure compatibility with a wide range of components. Its construction focuses on providing the necessary attachment points and clearances for a functional build.

Material and Build

The primary material is aluminium alloy, chosen for its favourable strength-to-weight ratio in bicycle frame manufacturing. The frame includes a disc brake mount on the rear triangle, which is a standard fitting for post-mount or flat-mount style calipers. The internal cable routing ports are designed to accept housing for both derailleur and brake cables, contributing to a tidy final assembly. The frame is supplied with a brake bracket, which is necessary for mounting the rear brake caliper correctly.

Size and Practical Fit

The frame geometry includes a 590mm top tube length, which influences the riding position and reach. The head tube measures 44-55 * 110mm, accommodating a corresponding headset and fork steerer tube. A significant fitting choice is the seatpost diameter of 30.8mm, available in either 410mm or 460mm length options, allowing the rider to select the post that offers the appropriate minimum insertion and height adjustment for their needs. The bottom bracket shell is a standard 34 * 68mm threaded or press-fit interface, and the rear dropout spacing is 135mm, which is a common standard for mountain bike rear hubs.

Uses and Placement

This frame is the central component for constructing a hardtail mountain bike, where the rear suspension is provided by the frame's material flex and the rider's technique. It forms the basis for a personal build project.

Event or Professional Use

As a core component, this frame can be built into a bicycle suitable for recreational trail riding, cross-country cycling, or commuting on varied terrain. The 29-inch wheel compatibility offers improved rollover capability over obstacles compared to smaller wheel sizes. The disc brake readiness makes it a practical choice for riding in conditions where rim brakes might be less effective, such as in wet weather or on steep, technical descents.

Everyday Home Use

For the home mechanic or cycling enthusiast, this frame provides a starting point for a custom bicycle build. The internal routing, while potentially requiring more effort to install cables initially, results in a finished bike that is easier to clean and maintain, as cables are less exposed to dirt and grime. The choice between the two seatpost lengths allows the final bike to be tailored more precisely to the primary rider's dimensions.

Benefits and Buying Value

The value of this product lies in its role as a foundational part for a bicycle that can be specified with the exact components the rider desires, from groupset to wheels.

Reuse and Low Maintenance

An aluminium frame is generally resistant to corrosion and, with proper care, can have a long service life. The internal cable routing can prolong cable life by shielding it from the elements. As a frame-only product, it allows for the reuse or selection of new components, enabling upgrades or repairs over the bicycle's lifespan without being tied to a complete pre-built bike's specifications.

Why Choose This Product

This frame is a suitable choice for riders or builders looking for a 29-inch hardtail platform with modern features like disc brake mounting and internal routing. The provided dimensional data, such as the head tube and bottom bracket specifications, allows for informed component compatibility checks before purchase. The inclusion of two seatpost length options directly addresses a common fit variable, adding practical value for a wider range of users.
