29-inch aluminium alloy mountain bike frame with disc brake mount and internal routing
This aluminium alloy frame forms the core structure for a 29-inch wheel mountain bike, commonly known as a 29er. Its design incorporates modern features like mounts for disc brakes and internal cable routing, making it a practical starting point for building a bike suited to trail riding and general off-road cycling. The frame is offered in a black green finish and two distinct riser sizes, providing options for different rider preferences and setups. It arrives with a brake bracket included, ready for component assembly.
Features and Construction
The frame's construction focuses on key performance and compatibility aspects for mountain biking. Its geometry and build are centred around accommodating large 29-inch wheels, which can offer improved roll-over capability on rough terrain.
Material and Build
The primary construction material is aluminium alloy, chosen for its favourable strength-to-weight ratio. The frame features internal cable routing, where gear and brake cables run inside the frame tubes. This design helps shield cables from mud, water, and trail debris, potentially reducing maintenance, and contributes to a sleeker overall appearance. The specified five-way measurement of 34*68mm relates to the junction where the seat tube, top tube, and down tube meet.
Size and Practical Fit
The frame is detailed with several key dimensions that influence bike fit and handling. The head tube measures 44-55*110mm, the top tube (listed as beam length) is 590mm, and the rear fork length is 385mm. Crucially, it is available with two different riser sizes: 30.8*410mm and 30.8*460mm. This choice allows riders or builders to select a frame with a stack height that better matches their torso length and riding style, affecting overall comfort and cockpit setup.
Uses and Placement
This frame is the foundational component for a complete mountain bike. Its design parameters dictate the type of riding it is best suited for and the components required to build a functional bicycle.
Event or Professional Use
As a 29er frame with disc brake compatibility, it is appropriate for building bikes intended for trail riding, cross-country cycling, and general mountain biking. The 135mm open gear spacing indicates a design for a standard quick-release rear hub, which is common on many mountain bikes. Builders should ensure all selected components, including wheelset, fork, drivetrain, and brakes, are compatible with these frame specifications.
Everyday Home Use
For the home mechanic or cycling enthusiast, this frame provides a project base for creating a custom mountain bike. The internal routing, while cleaner, may require specific tools or techniques for cable installation compared to external routing. The inclusion of a brake bracket is a practical touch, as it is a small but necessary part for mounting the rear brake caliper.
Benefits and Buying Value
The value of this product lies in its role as a core bicycle component with specific, modern features. It offers a blank canvas for a custom build without the cost of a complete, pre-assembled bike.
Reuse and Low Maintenance
The aluminium alloy construction is resistant to rust, which is beneficial for a frame exposed to wet and muddy conditions. The internal cable routing can help prolong cable life by reducing direct exposure to the elements. As a standalone frame, individual components can be upgraded or replaced over time, unlike on some fully welded budget bicycles.
Why Choose This Product
This frame is a suitable choice for someone seeking a 29-inch mountain bike frame with contemporary features like a disc brake mount and internal cable routing. The option between two riser sizes adds a level of customisation for fit. It is important to note that this is just the frame; building a complete, rideable bike requires purchasing and correctly installing all other components, which involves additional cost, tools, and mechanical knowledge.
