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.
TRX WheelSystem
Charge Harder
Greater confidence on rugged descents. Power and agility for technical climbs. The new TRX WheelSystem features Wide Guard technology to soak up impacts and drastically reduce pinch flats. A broad 30mm inner rim width and robust 5mm sidewalls allow you to run lower tire pressures for better traction and control when things get rowdy. The optimized carbon layup of the rims minimizes weight, and a 72-tooth hub delivers instant engagement—so you can climb and accelerate with power and speed.
Key Performance Factors
REDUCED RISK OF FLATS
New Wide Guard rim technology features a broad 30mm inner rim width and a robust 5mm sidewall to reduce the risk of impact punctures. In lab tests, these composite rims showed a 29.6% improvement in puncture protection over the previous generation TRX WheelSystem.
MORE TRACTION
The combination of wider composite rims and the new 5mm thick sidewall allow you to run much lower tire pressure without the need of heavy tire inserts. The result is better grip and control on rough, technical trails.
INSTANT ENGAGEMENT
Lightweight composite rims combined with an industry-leading 72-tooth pawl driver results in rapid power transfer and acceleration. The rear hub’s oversized drive-side hub body bearing, axle and ring nut combine with the enlarged pawls to increase stiffness and durability.
Highlights
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.

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
Dynamic Balanced Lacing
Engineered with more leverage on the “pulling” spoke and less on the “pushing” spoke, DBL technology maximises the performance of the wheel while it’s in a dynamic state by forming a perfect balance of spoke tension to deliver optimal transmission stiffness and braking performance.
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.
