TRX HD MTB WheelSystem

Designed for the rugged demands of aggressive trail and enduro riding, including E-MTB, the TRX HD WheelSystem features purpose-built hubs engineered for high-torque loads, plus Wide Guard rim technology for increased rim strength and pinch-flat protection.

Key Performance Factors

HIGH-TORQUE RESISTANCE

Powerful motor support, rider input and rough terrain place heavy demands on the hub. To handle those forces, the WheelSystem uses 3D-printed titanium ratchet rings that combine high strength, low weight and corrosion resistance. The design delivers a 20% strength increase over the previous generation, with excellent fatigue resistance for high-torque operation.

EFFICIENT POWER TRANSMISSION

The hub features an industry-leading 72-tooth Helical-Bevel Ratchet system, engineered for fast engagement and efficient power transfer under the high-torque demands of aggressive trail, enduro and E-MTB riding. A tighter bearing gap creates a compact, stable internal structure that helps reduce wear, while dual toothed discs engage quickly and evenly to distribute force more consistently under heavy loads. A 10° helical interface between the hub and ratchet rings helps reduce component stress while maintaining consistent torque transfer. The 72-tooth ratchet design delivers immediate response and precise power delivery when every pedal stroke counts.

TIRE & RIM PROTECTION

When a wheel strikes a sharp edge at speed, pinch flats and rim damage can occur. Refined Wide Guard technology broadens the contact point between rim and tire with a strong 5mm sidewall, while the curved rim profile improves obstacle rollover and helps reduce impact forces on the tire and rim.

Techs & Features

Optimized Carbon Lay-Up

Giant optimized reinforced layup places extra maximum-strength carbon fiber only where needed, creating a robust structure at minimal weight.

Dynamic Balanced Lacing

Since its introduction in 2015, Dynamic Balanced Lacing (DBL) has been the cornerstone of Giant WheelSystems. DBL ensures that spokes are set for optimal tension when under dynamic load, resulting in enhanced durability and pedaling efficiency. The enlarged DBL hub flange also increases the spoke bracing angles, which boosts overall torsional/transmission and lateral stiffness for better power transfer and more stable sprinting.

Wide Guard Technology

When your wheel hits a sharp or square edge, especially at speed, pinch flats and rim damage can occur. Wide Guard technology minimizes this risk by broadening the contact point between the rim and tire with a solid 5mm rim sidewall. That means you can skip the heavy tire inserts to have less unsprung weight on your bike and allow your suspension to perform better. The wide sidewalls also better protect your wheel from big impacts, reducing the possibility of rim damage.

Hookless Rim Design

Hookless rim design enhances overall durability, offers a wider inner rim width without adding extra weight and also helps create a more round tire shape providing superior grip and handling as well as added sidewall support when cornering. Additionally, without the rim hook to “push” the tire bead inward, hookless rim design offers a more seamless airflow between the tire and the sidewall of the rim, resulting in less drag and improved aero performance when compared to standard hook-type rims.
