29-Inch Aluminium Mountain Bike Frame with Disc Brake Mounts and Internal Routing

This 29-inch aluminium alloy mountain bike frame provides the core foundation for building a modern hardtail bike suited to trail riding and cross-country use. Its specifications are geared towards contemporary component standards, including mounts for disc brakes and internal cable routing channels to keep lines tidy. Offered in a Black Green finish, the frame is available with a choice of seat tube lengths, allowing builders to select the option that best matches their intended rider's geometry. This introduction covers the key dimensional data and intended use case derived from the provided specifications.

Features and Construction

The frame's design focuses on compatibility with current mountain bike parts and a clean aesthetic. The construction and specified dimensions dictate how it will fit together with other components and the type of ride it is likely to provide.

Material and Build

The frame is built from aluminium alloy, a standard material choice for mountain bike frames that offers a favourable strength-to-weight ratio. It features internal cable routing, which guides brake and gear cables through the frame's main tubes instead of along the outside, contributing to a cleaner look and offering some protection from debris. The inclusion of a dedicated brake bracket in the package indicates the frame is designed for a disc brake system, a modern standard for consistent braking performance in varied conditions.

Size and Practical Fit

The frame's geometry is defined by several key measurements. The 29-inch wheel size is stated, which influences the overall frame proportions and ride characteristics, typically offering improved roll-over capability on rough terrain. The head tube measures 44-55mm by 110mm, which will determine compatible headset and fork steerer specifications. The top tube length is 590mm, and the rear chainstays are 385mm long, contributing to the bike's cockpit room and rear-end geometry. Crucially, the seat tube is offered in two lengths: 410mm and 460mm. This choice allows for better accommodation of different rider leg lengths and inseam measurements within the same frame model.

Uses and Placement

With its stated specifications, this frame is positioned for specific types of cycling. Its intended use can be inferred from its wheel size, frame material, and feature set common in particular riding disciplines.

Event or Professional Use

While not a complete bike, this frame serves as the starting point for a custom build. It could form the basis of a cross-country race bike or a reliable trail bike for regular off-road riding. The 135mm rear dropout spacing is a standard quick-release dimension suitable for a wide range of mountain bike hubs. The 34mm by 68mm bottom bracket shell size is compatible with many modern threaded bottom bracket standards, allowing for a broad selection of cranksets. These specs make it a viable candidate for a performance-oriented or dependable recreational mountain bike build.

Everyday Home Use

For the home mechanic or cycling enthusiast, this frame represents a project. Building a bike from a frame requires sourcing wheels, a fork, a drivetrain, brakes, and finishing kit. The process allows for a highly personalised result. The provided brake bracket is a small but essential part for mounting a rear disc brake caliper. Once built, a bike using this frame would be capable of handling forest trails, park paths, and general off-road exploration, assuming all other components are chosen appropriately for the intended use.

Benefits and Buying Value

The value of this product lies in its role as a foundational component for a custom bike. Its benefits are tied to the specifications it offers and the flexibility they provide to the builder.

Reuse and Low Maintenance

As a frame, this product's lifecycle is inherently long. A well-maintained aluminium frame can serve as the base for multiple component iterations over many years. Frames generally require minimal maintenance themselves beyond occasional inspection for damage, cleaning, and ensuring all threaded interfaces (like the bottom bracket and headset) are properly installed and secure. The durability is a function of the aluminium alloy material and the quality of its construction, as stated in the source text.

Why Choose This Product

This frame may be selected for its specific combination of size and features. The 29-inch wheel size is a primary differentiator for riders who prefer that standard. The option between two seat tube lengths (410mm and 460mm) is a key practical advantage, providing a degree of fit customisation not always available on stock frames. The inclusion of internal routing and disc brake mounts makes it compatible with contemporary, high-performance components without requiring external adapters or modifications, saving time and effort during the build process.
