29-inch Aluminium Alloy Mountain Bike Frame with Disc Brake Mount and Inner Routing

This mountain bike frame serves as the core structural component for building a modern 29-inch wheel mountain bike. Constructed from aluminium alloy, it is designed to offer a reliable and relatively lightweight platform for trail riding. Key features include a dedicated disc brake mount, which accommodates the powerful braking performance demanded by modern mountain biking, and internal cable routing (inner line) for a sleeker look and better cable protection. The frame is offered in a black green colour and provides a choice between two riser sizes, allowing for some customisation in the final bike's cockpit setup based on rider preference and intended use.

Features and Construction

The frame's design incorporates several elements focused on modern mountain bike standards and practical assembly. Its construction prioritises compatibility with widely available components to simplify the build process for mechanics and enthusiasts.

Material and Build

The primary construction material is aluminium alloy, a standard choice for mountain bike frames that balances durability with manageable weight. The frame includes a disc brake mount, a standard feature for contemporary mountain bikes that allows for the fitting of hydraulic or mechanical disc brakes. Furthermore, it employs inner line routing, meaning the cables for brakes and gears run inside the frame tubes. This design choice helps protect the cables from external damage and results in a cleaner overall aesthetic with fewer exposed lines.

Size and Practical Fit

The frame is designated for 29-inch wheels, a common size for modern mountain bikes known for rolling over obstacles efficiently. It provides two specific riser size options: 30.8mm diameter by 410mm length or 30.8mm diameter by 460mm length. This choice allows the builder to influence the handlebar height and, consequently, the riding position. Other critical dimensions include a 590mm beam length, a 385mm rear fork length, and a head tube sized at 44-55mm by 110mm, all of which determine the frame's geometry and the fit of the final bicycle.

Uses and Placement

This frame is the starting point for creating a complete mountain bike suited for various off-road activities. Its specifications align with common standards for trail and cross-country riding builds.

Event or Professional Use

For competitive or serious recreational mountain biking, this frame provides a blank canvas. The 29-inch wheel platform, disc brake compatibility, and aluminium construction are typical specifications for cross-country and general trail bikes. Builders can select high-performance components like specific suspension forks, drivetrains, and wheel sets to create a bike tailored for racing or demanding trail centres, leveraging the frame's modern standards like the 135mm rear spacing.

Everyday Home Use

For the home mechanic or enthusiast building a personal trail bike, this frame offers clear parameters to guide component selection. The known dimensions help ensure purchased parts like the seat post, headset, and bottom bracket will fit correctly. The inclusion of a brake bracket in the package is a practical touch for the initial assembly stage. The resulting bike would be suitable for weekend trail rides, forest paths, and general off-road exploration.

Benefits and Buying Value

Purchasing a frame separately allows for a highly customised bike build. This product provides the essential foundation with several decided specifications that narrow down compatible parts.

Reuse and Low Maintenance

A well-maintained aluminium frame is a long-lasting component. As a central part of the bicycle, it can outlast many other wear-and-tear parts like chains, cassettes, and tyres. The disc brake mount and internal routing are durable features that do not require ongoing maintenance themselves, contributing to the frame's longevity as a platform for future upgrades or component replacements over the bike's lifespan.

Why Choose This Product

This frame is a suitable choice for someone seeking to build a 29-inch mountain bike with disc brakes without the cost of a complete, high-end factory model. It provides the critical geometry and mounting standards, leaving the selection of other components to the builder's preference and budget. The option to choose between two riser sizes adds a degree of fit customisation right from the start, which can be more cost-effective than replacing parts later to adjust the riding position.
