29-inch mountain bike aluminium alloy frame with disc brake mount for adult hybrid bikes, featuring a lightweight aluminium construction, inner cable routing, a 410mm or 460mm seat post, and available in a Black Green colour
29-inch Aluminium Mountain Bike Frame with Disc Brake Mount and Internal Routing

This aluminium alloy mountain bike frame serves as the core structure for building a modern 29-inch hybrid or trail bicycle. Engineered for adult riders, it combines the lightweight properties of aluminium with practical features like disc brake mounts and an internal cable routing system. The frame's specific geometry, including a 590mm top tube and 385mm chainstay length, provides a stable platform for handling varied terrain. Supplied in a Black Green colour and with a choice of seat post lengths, it offers a solid foundation for cyclists to create a personalised bike suited to commuting, light trail riding, or general fitness.
Features and Construction

This frame is built with a focus on modern bicycle standards and practical assembly features, providing a versatile base for a custom build.
Material and Build
The frame is constructed entirely from aluminium alloy, a material favoured for its favourable strength-to-weight ratio in bicycle manufacturing. This choice contributes to a lighter overall bike compared to steel alternatives, which can improve acceleration and handling. The construction includes dedicated mounting points for a disc brake caliper, a feature that offers consistent braking power in wet or muddy conditions compared to traditional rim brakes. Furthermore, the frame utilises an 'innerline' or internal cable routing system. This design guides brake and gear cables through the inside of the frame tubes, resulting in a cleaner external appearance and reduced risk of cables catching on obstacles or becoming damaged.
Size and Practical Fit
Designed for 29-inch wheels, this frame is intended for adult riders and offers a capable platform for various riding styles. The geometry includes a 590mm top tube length and a 385mm rear fork (chainstay) length, which contribute to a stable ride feel. A key fitting aspect is the seat post, which is available in two riser sizes: 410mm and 460mm. This choice allows the build to be tailored to suit different rider heights and leg lengths for an optimal riding position. The seat post itself interfaces with the frame via a 34mm diameter tube that extends 68mm into the frame's seat tube, ensuring a secure and adjustable fit.
Uses and Placement

This frame's specifications make it suitable for a range of cycling applications, from upgraded recreational riding to more focused off-road use.
Event or Professional Use
While a professional race frame would have more specialised geometry and materials, this aluminium frame is perfectly suited for building a reliable bike for charity sportives, endurance events, or amateur racing where a balance of performance, durability, and value is key. Its disc brake compatibility is a significant advantage for events held in unpredictable weather, ensuring braking consistency. The internal routing also contributes to a more aerodynamic and professional-looking finish for the completed bike.
Everyday Home Use
For the home mechanic or enthusiast looking to build a custom bike, this frame presents an excellent starting point. It is ideal for creating a versatile hybrid bike for daily commutes, weekend trail exploration, or general fitness riding. The standard dimensions, such as the 44-55 * 110mm head tube and 135mm rear hub spacing, ensure wide compatibility with common component groups available on the market, simplifying the sourcing process for handlebars, forks, wheels, and drivetrains.
Benefits and Buying Value

Choosing this frame for a bike build offers several practical advantages centred on modern standards, compatibility, and long-term usability.
Reuse and Low Maintenance
The aluminium construction is naturally corrosion-resistant, which, with basic care, helps maintain the frame's appearance and integrity over time. The use of industry-standard sizing for interfaces like the head tube and rear dropouts means that components can potentially be transferred to a future frame if desired. The internal cable routing not only looks tidy but also protects the cables from external wear, which can extend their service life and reduce maintenance frequency.
Why Choose This Product
This frame is a practical choice for riders seeking to build or upgrade a 29-inch bike with contemporary features without a premium price tag. Its aluminium build offers a known performance benchmark, while the inclusion of disc brake mounts and internal routing brings it in line with current bicycle design trends. The provision of a brake bracket in the package and the two seat post options add immediate value, simplifying the initial build process. It represents a focused component that delivers on its core promises of compatibility, modern functionality, and a solid foundation for a personalised bicycle.
