29-inch aluminium alloy mountain bike frame with disc brake compatibility in black green

This 29-inch mountain bike frame offers cyclists a solid platform for building a capable off-road or trail bicycle. Constructed from aluminium alloy, it provides the structural integrity needed for challenging terrain while maintaining a practical weight profile for responsive handling. The frame comes in a distinctive black green finish and includes important features like inner cable routing and disc brake compatibility. With two seat post length options available, riders can select the configuration that best matches their riding position and height requirements.
Features and Construction

The frame incorporates several design elements specifically suited to mountain biking applications. From its wheel size compatibility to its component mounting points, each feature addresses practical considerations for trail riding performance and bicycle assembly.
Material and Build
The aluminium alloy construction provides a balance of strength and weight that makes it suitable for mountain biking applications. This material choice offers good durability for off-road use while avoiding excessive weight that could hinder climbing performance. The frame includes precision-machined interfaces for components, with a 34 * 68mm bottom bracket shell that accommodates standard crankset systems. The integrated head tube measuring 44-55 * 110mm provides secure steering assembly for responsive trail handling.
Size and Practical Fit
Designed for 29-inch wheels, this frame creates a bicycle with good ground clearance and rolling efficiency over varied terrain. The 590mm top tube length contributes to a balanced riding position suitable for both climbing and descending. Riders can choose between two seat post options - 410mm or 460mm lengths - allowing adjustment to match individual leg length and preferred saddle height. The 30.8mm seat post diameter is a common standard, providing compatibility with a wide range of saddle components.
Uses and Placement

This frame serves as the foundation for building complete mountain bicycles suited to different riding styles and terrains. Its specifications make it appropriate for various cycling applications, from recreational trail riding to more committed off-road adventures.
Event or Professional Use
For riders interested in trail centre riding or mountain bike events, the 29-inch wheel size offers advantages in rolling over obstacles and maintaining momentum. The disc brake compatibility ensures powerful stopping performance essential for technical descents and variable trail conditions. The 135mm open gear spacing accommodates modern mountain bike rear wheel hubs and gear systems, providing flexibility in component selection for different riding disciplines.
Everyday Home Use
For recreational cyclists building a trail bike for local woodland rides or countryside exploration, this frame provides a practical starting point. The aluminium alloy construction offers sufficient durability for regular use without requiring specialised maintenance. The inner cable routing helps protect control cables from dirt and moisture during rides, potentially extending component life and reducing maintenance frequency for everyday cycling enthusiasts.
Benefits and Buying Value

Choosing this frame as the basis for a mountain bike build offers several practical advantages for cyclists. From its component compatibility to its riding characteristics, it provides a solid foundation for creating a personalised trail bicycle.
Reuse and Low Maintenance
The aluminium alloy material resists corrosion better than some alternatives, potentially extending the frame's usable life with basic care. Standard component interfaces mean that if parts wear out or need upgrading, replacements are readily available from bicycle component suppliers. The simple colour scheme and clean lines allow for aesthetic customisation through component choices while maintaining a cohesive appearance.
Why Choose This Product
This frame offers a practical starting point for building a 29-inch wheel mountain bike with modern features like disc brake compatibility and inner cable routing. The availability of two seat post length options provides flexibility in achieving a comfortable riding position. For cyclists who enjoy selecting their own components or want to upgrade an existing bicycle, this frame serves as a blank canvas that can be tailored to specific riding preferences and terrain requirements.
