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

This 29-inch aluminium alloy mountain bike frameset offers a contemporary foundation for constructing a hardtail or full-suspension compatible trail bicycle. Designed around modern standards, it features mounts for disc brakes and employs internal cable routing (innerline) to guide brake and gear cables through the frame for improved protection and a cleaner aesthetic. The frame is supplied in a Black Green finish and provides a choice between two seat post (riser) sizes, allowing for customisation based on rider height and intended use. Please be aware that this product is a frameset only; it does not include a fork, wheels, groupset, or any other bicycle components necessary for a complete build.

Features and Construction

The frame's design focuses on compatibility with current mountain bike components and tidy cable management. Its construction and specified dimensions provide the core geometry for your build.

Material and Build

The primary frame material is aluminium alloy, chosen for its favourable strength-to-weight ratio, making it a common and practical choice for mountain bike frames. The build incorporates a 44-55 * 110mm head tube, which is designed to accept a standard tapered headset and fork steerer. A key feature is the internal cable routing system, which routes cables inside the frame's main tubes to shield them from dirt, moisture, and accidental snags, contributing to smoother operation and lower maintenance.

Size and Practical Fit

This frame is designed for 29-inch mountain bike wheels, a standard that offers improved roll-over capability on rough terrain. A significant fit adjustment comes from the two available riser (seat post) size options: 30.8mm diameter by 410mm length, and 30.8mm diameter by 460mm length. This choice allows the builder to select a seat post length better suited to the rider's leg length and the frame's intended riding position, whether for more aggressive trail riding or a more upright posture.

Uses and Placement

This frameset is intended as the central component for building a new mountain bike or as a replacement/upgrade frame for an existing bike. Its specifications guide its application.

Event or Professional Use

For bike builders, workshops, or enthusiasts creating a custom mountain bike, this frame provides a blank canvas. Its disc brake compatibility and internal routing are expected features in modern trail, cross-country, or all-mountain bike builds. The 135mm rear axle spacing (open gear) is a standard quick-release dimension for hardtail mountain bikes, ensuring compatibility with a wide range of rear hubs and wheelsets.

Everyday Home Use

For the home mechanic building a personal trail bike, the clear specifications—such as the 590mm beam length, 385mm rear fork length, and 34 * 68mm five-way (seat tube cluster)—provide essential measurements for ensuring other components like the crankset, rear shock (if applicable), and seat post will fit correctly. The Black Green colour offers a neutral, understated finish suitable for various component colour schemes.

Benefits and Buying Value

The value of this frameset lies in its adherence to modern standards and the flexibility offered by its key specifications.

Reuse and Low Maintenance

As an aluminium frame, it is inherently rust-resistant, though regular cleaning after muddy rides is recommended to preserve bearings and finishes. The internal cable routing reduces the frequency of cable replacement due to contamination and protects the lines from external damage. The robust construction is designed for the rigours of mountain biking, suggesting potential for long service life when used within its design limits.

Why Choose This Product

This frame is a practical choice for anyone seeking a 29-inch aluminium mountain bike frame with contemporary features like disc brake mounts and internal cable routing. The inclusion of two riser size options adds a useful degree of customisation not always available. It represents a core component around which a reliable and modern mountain bike can be built, provided the builder sources all other necessary parts separately.
