29-inch mountain bike frame constructed from aluminium alloy featuring innerline cable routing and disc brake compatibility with five-way sizing of 34 * 68mm and black green colour options in 410mm and 460mm riser sizes
29-inch aluminium mountain bike frame with innerline routing and disc brake compatibility

This aluminium alloy frame is designed for constructing a 29-inch wheel mountain bike, offering a solid base for riders seeking a trail-capable build. Its specifications, including a 135mm open gear spacing and disc brake mounts, align with modern mountain bike standards, while the internal cable routing provides functional and visual benefits. The available sizing details, such as the 590mm beam length and 385mm rear fork length, give builders key measurements for component selection and fit. Offered in a black green colour, the frame includes a brake bracket and is presented with two riser size variants to suit different rider preferences and builds.
Features and Construction

The frame's design incorporates several features aimed at modern mountain bike performance and assembly convenience. Key structural elements are defined by precise measurements to aid in compatible component selection.
Material and Build
The primary construction material is aluminium alloy, chosen for its favourable strength-to-weight ratio in bicycle frame applications. The frame is engineered with disc brake mounts, allowing for the fitment of modern hydraulic or mechanical disc braking systems which are common on mountain bikes for consistent stopping power. A notable feature is the innerline cable routing, where gear and brake cables are intended to run inside the frame tubes, contributing to a sleeker appearance and offering some protection from dirt and moisture.
Size and Practical Fit
The frame is designated for 29-inch wheels, a standard size known for rollover capability on trails. Critical dimensions for build planning include a beam length of 590mm, a rear fork length of 385mm, and a head tube size specified as 44-55 * 110mm. The five-way component, measuring 34 * 68mm, relates to the frame's rear triangle and dropout area, which is a common interface for the rear wheel and drivetrain. The open gear spacing of 135mm is a standard width for mountain bike rear hubs, ensuring compatibility with a wide range of wheel sets.
Uses and Placement

This frame serves as the central component for creating a complete mountain bike, suitable for various riding applications from trail riding to general off-road use. Its specifications guide the selection of all other bicycle parts.
Event or Professional Use
For riders building a bike for trail centres, endurance riding, or recreational mountain biking, this 29-inch aluminium frame provides a conventional and reliable platform. The disc brake compatibility and 135mm spacing are typical requirements for such use, supporting components designed for varied terrain and conditions. The internal routing can be beneficial for maintaining cable function in muddy or dusty environments encountered during trail riding.
Everyday Home Use
As a project for home mechanics or enthusiasts looking to assemble a personalised bike, this frame offers clear specifications to work from. The provided dimensions, like the riser options of 410mm and 460mm, allow for tailoring the bike's geometry and cockpit setup to the individual rider. The inclusion of a brake bracket in the contents is a practical addition for the final assembly stage of the build.
Benefits and Buying Value

The value of this frame lies in its role as a defined starting point for a custom bike build, with specifications that match contemporary mountain bike standards.
Reuse and Low Maintenance
Aluminium as a frame material is known for its resistance to corrosion and generally requires minimal upkeep beyond cleaning. The internal cable routing, while potentially more complex to set up initially, can help preserve cable life by shielding them from direct exposure. The frame itself, as a structural component, is designed for long-term use and can be the basis for multiple component upgrades over time.
Why Choose This Product
This frame is a suitable choice for anyone needing a 29-inch mountain bike frame with disc brake mounts and internal routing. Its clearly stated aluminium construction and comprehensive set of provided dimensions reduce uncertainty during the parts sourcing and build process. The availability in two riser sizes (410mm and 460mm) within the same black green colour offers a degree of choice for fine-tuning the bike's standover height and fit.
