29-Inch Aluminium Alloy Mountain Bike Frame with Inner Routing and Disc Brake Compatibility

This 29-inch mountain bike frame provides cyclists with an aluminium alloy foundation specifically designed for off-road riding. The larger wheel size characteristic of 29-inch frames offers improved rollover capability over obstacles commonly encountered on trails, while the aluminium construction delivers a balance between weight reduction and structural integrity needed for challenging terrain. With inner cable routing that protects vital brake and gear cables from external elements, this frame maintains cleaner aesthetic lines while reducing the risk of trailside snags that can occur with exposed routing systems.
Features and Construction

Built for mountain biking applications, this frame incorporates several design elements that support trail riding performance. The disc brake compatibility ensures modern braking systems can be fitted, providing consistent stopping power regardless of weather conditions or trail surface moisture. The inner routing system channels cables through the frame rather than along exterior surfaces, protecting them from mud, debris, and potential damage during rides.
Material and Build
The aluminium alloy construction forms the core of this mountain bike frame, offering material properties suited to the demands of off-road cycling. Aluminium provides a favourable strength-to-weight ratio that helps maintain overall bike weight while ensuring the frame can withstand the impacts and stresses of trail riding. This material choice supports the frame's structural requirements without adding excessive mass that could hinder climbing efficiency or handling responsiveness on technical sections.
Size and Practical Fit
With a 29-inch wheel size specification, this frame accommodates the larger diameter wheels that have become standard in modern mountain biking for their improved obstacle rollover and momentum maintenance. The 590mm beam length influences rider positioning and cockpit space, while the rear fork length of 385mm and 135mm open gear spacing ensure compatibility with standard mountain bike components. The 30.8mm diameter riser available in 410mm or 460mm lengths allows for handlebar height adjustment to suit individual rider preferences and riding styles.
Uses and Placement

Designed specifically for mountain biking applications, this frame serves as the structural centrepiece for building a complete off-road bicycle. Its specifications target trail riding, cross-country cycling, and general mountain biking where the combination of 29-inch wheels and aluminium construction provides practical advantages. The frame's geometry and dimensions support the riding positions and handling characteristics preferred by mountain bikers navigating varied terrain.
Event or Professional Use
For competitive cycling or organised trail riding events, this frame offers a foundation that can be built upon with performance components. The disc brake compatibility ensures riders can utilise high-performance braking systems needed for technical descents and rapid speed changes during events. The 29-inch wheel size provides the rollover benefits valued in cross-country racing and endurance events where maintaining momentum over roots and rocks contributes to competitive performance.
Everyday Home Use
For recreational mountain bikers building their own bikes or replacing existing frames, this aluminium alloy frame provides a durable starting point. The inner routing reduces maintenance concerns by protecting cables from everyday trail debris, while the standardised dimensions ensure compatibility with commonly available components. The black green colour option offers aesthetic appeal that maintains its appearance through regular use on local trails and forest paths.
Benefits and Buying Value

This mountain bike frame delivers practical advantages through its material selection and design features. The aluminium alloy construction offers long-term durability that withstands trail riding conditions without specialised maintenance requirements. The inner routing system extends component life by reducing exposure to abrasive elements, while the disc brake compatibility ensures the frame remains usable with modern braking technology.
Reuse and Low Maintenance
The aluminium frame material resists corrosion that can occur with frequent exposure to trail moisture and cleaning products, supporting extended use over multiple seasons. The inner cable routing protects vital components from direct exposure to mud, water, and trail debris, reducing the frequency of cable replacement and adjustment. Standardised dimensions across critical areas like the head tube and rear fork ensure compatibility with replacement parts as components wear or upgrade opportunities arise.
Why Choose This Product
Select this frame for its combination of 29-inch wheel compatibility, aluminium construction, and practical features like inner routing and disc brake mounts. The specific dimensions including the 590mm beam length and 385mm rear fork length create predictable handling characteristics when paired with appropriate components. For riders building a mountain bike or replacing an existing frame, these specifications provide a clear foundation for component selection and bike assembly.
