29-inch aluminium mountain bike disc brake frame with inner line routing and 410mm/460mm riser options

This 29-inch aluminium alloy mountain bike disc brake frame provides builders with a solid foundation for creating either BMX or MTB bicycles. The frame features inner line routing that channels cables through the frame tubing rather than externally, reducing snag points and creating cleaner aesthetics. With a head tube measuring 44-55 * 110mm and 135mm open gear spacing, this frame accommodates standard mountain bike components commonly available in the market. The black green colour option maintains a subdued appearance suitable for various bike styles, while the choice between 410mm and 460mm riser sizes allows builders to tailor the frame geometry to their specific riding preferences and body dimensions.

Features and Construction

This mountain bike frame incorporates several design elements that facilitate building a complete bicycle while maintaining compatibility with standard components.

Material and Build

Constructed from aluminium alloy, this frame provides the strength necessary for mountain biking applications while keeping weight manageable. The material choice reflects common industry practice for performance-oriented bicycle frames, offering durability without excessive mass. The disc brake compatibility allows builders to install modern braking systems, while the 34 * 68mm five-way measurement provides precise reference points for component mounting and alignment during assembly.

Size and Practical Fit

With its 29-inch wheel size designation, this frame accommodates larger mountain bike wheels that have become standard for many off-road cycling applications. The 590mm beam length establishes the main frame dimension, while the 385mm rear fork length determines the rear triangle geometry. These measurements contribute to the overall ride characteristics builders can expect from completed bicycles using this frame. The 30.8mm diameter riser options at either 410mm or 460mm lengths allow customization of handlebar height and rider position.

Uses and Placement

This frame serves as the central structural component for building complete bicycles tailored to specific riding disciplines and preferences.

Event or Professional Use

For competitive BMX or mountain biking applications, this frame provides the necessary foundation for building performance-oriented bicycles. The 135mm open gear spacing accommodates standard drivetrain components used in both disciplines, while the disc brake compatibility supports modern braking systems preferred for consistent performance in varied conditions. The aluminium alloy construction offers responsive handling characteristics valued by riders in both casual and competitive settings.

Everyday Home Use

For recreational cyclists building custom bicycles, this frame offers a starting point for creating personalized mountain bikes. The inner line routing contributes to cleaner aesthetics and reduced maintenance by protecting cables from external elements. The availability of two riser sizes (410mm and 460mm) allows builders to tailor the bicycle's fit to their body dimensions and riding style preferences, potentially improving comfort during extended use.

Benefits and Buying Value

This frame provides several practical advantages for bicycle builders seeking specific characteristics in their completed bikes.

Reuse and Low Maintenance

The aluminium alloy construction resists corrosion and maintains structural integrity with basic care, potentially extending the frame's usable lifespan. The inner line routing protects brake and gear cables from environmental exposure and physical damage, potentially reducing maintenance frequency compared to externally routed systems. Standard component compatibility means replacement parts remain readily available should repairs become necessary in the future.

Why Choose This Product

Builders selecting this frame gain specific dimensional characteristics including the 29-inch wheel compatibility, 590mm beam length, and 385mm rear fork length that collectively influence the finished bicycle's handling. The inclusion of a brake bracket facilitates installation of disc brake systems, while the head tube and gear spacing measurements ensure compatibility with widely available components. The option between 410mm and 460mm riser sizes provides flexibility in determining final bicycle geometry based on individual rider requirements.
