Discover the Trifox SDY20 carbon MTB frame. This lightweight 29er hardtail frame combines a stiff, efficient carbon layup with the modern SRAM Universal Derailleur Hanger (UDH) for unparalleled performance and compatibility. Perfect for XC and trail riders.



The Quest for the Perfect Hardtail

In the world of mountain biking, the hardtail holds a special place. It’s a pure, direct connection between rider and trail, rewarding skill and fitness with unmatched efficiency. But not all hardtails are created equal. The modern rider demands a frame that is not only stiff and lightweight but also future-proof, ready to accept the latest components without compromise.

Enter the Trifox SDY20 Carbon MTB Hardtail Frame. This frame is engineered from the ground up to meet these exact demands. By fusing a high-performance carbon fiber 29er design with the game-changing SRAM Universal Derailleur Hanger (UDH), the SDY20 isn't just another frame—it's a smart, long-term investment for discerning riders.

A Deep Dive into the SDY20's Carbon ChassisAt the heart of any great frame is its material and construction. The SDY20 is meticulously crafted from unidirectional carbon fiber, a process that places each strand of carbon in a specific direction to optimize strength and stiffness where it's needed most.

Unmatched Stiffness: The primary benefit of this advanced carbon layup is phenomenal power transfer. When you put power into the pedals, the SDY20 translates it directly into forward motion with minimal flex. This results in explosive acceleration and climbing efficiency that will make you feel stronger on every ride.

Feather-Light Weight: Carbon fiber's incredible strength-to-weight ratio means the SDY20 frame is remarkably light. Shedding weight from the frame, the largest single component of your bike, has a dramatic effect on overall ride feel, making the bike more agile and easier to handle, especially on technical climbs..

29er Performance: The frame is designed exclusively for 29-inch wheels, the current gold standard for mountain biking. Larger wheels roll over obstacles with greater ease, maintain momentum better, and provide increased traction and confidence through rough sections. The SDY20’s geometry is optimized to harness all the benefits of the 29er platform.

The Game-Changing Upgrade: Why the UDH MattersThis is where the Trifox SDY20 truly separates itself from the pack. The inclusion of the SRAM Universal Derailleur Hanger (UDH) is more than a minor spec update; it's a fundamental shift in compatibility and durability.

Universal Compatibility: As the name suggests, the UDH is an industry-standard hanger. It’s designed to work with an enormous range of derailleurs, most notably SRAM's current and future Eagle Transmission (AXS) groupsets. This means your SDY20 frame is ready for the latest wireless shifting technology right out of the box. No more searching for proprietary, model-specific hangers.

Enhanced Durability & Protection: The UDH is designed to be a sacrificial component. In the event of an impact to your rear derailleur, the UDH is engineered to break before the much more expensive derailleur or frame does. This simple, smart design can save you hundreds of dollars in repairs and is a critical feature for any mountain bike that sees real trail use.

Future-Proofing Your Investment: By building your bike around a frame with a UDH, you are ensuring that it will be compatible with the vast majority of drivetrain upgrades for years to come. The UDH is quickly becoming the new norm, and the SDY20 puts you on the right side of that evolution.:

Built for Modern Standards: More Than Just UDHThe forward-thinking design of the SDY20 extends beyond the derailleur hanger. This frame is built to accommodate the best modern components.

Boost Spacing (148x12mm Thru-Axle): Boost hub spacing increases wheel stiffness and strength, providing better alignment for wider tires and improving handling precision.

Modern Geometry: The frame features a contemporary geometry that strikes a perfect balance for XC and trail riding. It provides a confident, stable stance on descents while remaining agile and responsive for climbing and technical maneuvers.



Who Is The Trifox SDY20 Carbon Frame For?

This frame is the ideal foundation for:

The Weight-Conscious Racer: Looking for every possible advantage in stiffness and weight savings.

The Trail Enthusiast: Wants a lively, efficient, and modern hardtail that can tackle a variety of terrain with confidence.

The Tech-Savvy Builder: Planning a custom build and wants a frame that is compatible with the latest and greatest components, including wireless groupsets.

The Upgrader: Seeking to move from an older aluminum frame to a high-performance carbon platform without sacrificing future compatibility.

A Frame Ready for Tomorrow's TrailsThe Trifox SDY20 Carbon MTB Hardtail Frame is a masterclass in modern bicycle design. It doesn't force you to choose between a stiff, lightweight carbon chassis and future-proof compatibility. It delivers both in one elegant package.

By combining the race-winning performance of its 29er carbon frame with the industry-standard SRAM UDH upgrade, the SDY20 offers a compelling value proposition. It’s a frame that feels incredible to ride today and is smartly equipped for the innovations of tomorrow.
