A solid 5mm rim sidewall helps minimize the risk of impact damage by broadening the contact point between a sharp or square-edged object and the rim and tire. This also allows riders to forgo heavy tire inserts, which means less unsprung weight for better suspension performance.

CHARGE HARDER
Combining durability and efficiency, the TRX WheelSystem features a new 5mm wide rim-edge design to strengthen the wheel, reduce pinch flats and allow lower tire pressure for better traction and control. Optimized carbon layup provides a robust yet lightweight structure and pairs with a 72-tooth hub to maximize power transfer.

PUNCTURE PROTECTION
Lab tests simulated pinch flat scenarios by pressinga sharp, square-edged block against the tire until it hit the rim edge and punctured the tire. In test after test, the TRX WheelSystem withstood the highest impact forces without flatting, outperforming previous generation TRX and other top wheels in the category by up to 44 percent.
3
MORE TRACTION
A broad 30mm inner rim width and robust 5mm sidewalls allow for much lower tire pressure, giving you better traction and control on rough, technical climbs and descents. A low 22mm rim depth further improves compliance and ride feel.

INSTANT ENGAGEMENT
The combination of a lightweight carbon rim layup and industry-leading 72-tooth pawl driver results in rapid power transfer as you pedal over obstacles and accelerate out of corners. In the rear, an oversized drive-side hub body bearing, axle and ring nut combine with enlarged pawls to increase stiffness and durability.

E-MTB OPTION
The E-bike specific E-TRX WheelSystem shares the same features and technologies but with an extra-strong steel axle and driver body on the rear hub to handle added forces and torque.

Techs & Features
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.
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.
