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

This black green aluminium alloy frame forms the core of a 29-inch wheel mountain bike, offering a modern platform for riders building a trail-ready bicycle. Its design incorporates practical features for performance and maintenance, including mounts for disc brakes and a system of inner cable routing. The frame is supplied with two different seatpost lengths, allowing for adjustment to suit various rider statures and riding styles, providing a foundational element for a custom or replacement build.

Features and Construction

The frame's construction focuses on providing a reliable and adaptable base for a mountain bike. Key aspects of its design are centred on compatibility with modern components and ease of assembly for a functional finished bike.

Material and Build

Constructed from aluminium alloy, this frame aims to deliver a balance between structural strength and weight, a common choice for mountain bike frames. The build includes a 34 * 68mm bottom bracket shell, which is a standard dimension for accommodating various crankset types. The inclusion of a dedicated brake bracket in the package facilitates the direct mounting of a rear disc brake caliper to the frame.

Size and Practical Fit

The frame is designed for 29-inch wheels, a size favoured for its roll-over capability on rough terrain. It offers a 590mm top tube length and a head tube measuring 44-55 * 110mm, which influences the bike's front-end geometry and handlebar height. A significant fit adjustment is provided by the choice between a 410mm or a 460mm length seatpost, allowing the saddle height to be set appropriately for different leg lengths.

Uses and Placement

This frame is intended as a component for creating a complete bicycle. Its design cues point towards its primary use in off-road cycling, where its features provide tangible benefits.

Event or Professional Use

For riders building a bike for trail riding, cross-country, or general mountain biking, the frame's disc brake mounts allow for the use of powerful hydraulic or mechanical disc brakes, which offer consistent performance in wet and muddy conditions. The 135mm rear spacing is a standard for mountain bike hubs, ensuring wide compatibility with wheel sets.

Everyday Home Use

For the home mechanic or enthusiast assembling a personal bike, the inner cable routing contributes to a cleaner look and helps protect gear and brake cables from external damage. The provided brake bracket simplifies one part of the build process. The frame serves as a central project piece around which other components like forks, wheels, and drivetrains are selected.

Benefits and Buying Value

The value of this frame lies in its role as a foundational component. It offers a specific set of measurements and features that dictate the final bike's characteristics and component compatibility.

Reuse and Low Maintenance

As a structural component, a well-maintained frame can have a long service life across multiple component upgrades. The aluminium construction is resistant to rust. The inner cable routing can reduce the frequency of cable housing replacement by keeping it shielded from the elements and trail debris.

Why Choose This Product

This frame is a suitable choice for someone seeking a 29-inch aluminium mountain bike frame with modern features like disc brake mounts and internal routing. The option of two seatpost lengths adds a degree of fit customisation from the outset. It provides a blank canvas for a build tailored to specific riding needs, whether for replacement, upgrade, or a new project.
