TRA WheelSystem
Factory Fast
Proven under the most demanding conditions by Giant Factory Off-Road Team racers, the new TRA WheelSystem boasts Wide Guard technology to reduce the risk of rim damage and pinch flats. A broad 30mm inner rim width and thick 5mm rim walls allow you to run lower tire pressures for better traction without the need for heavy tire inserts. Hollow rim wall construction minimizes weight, and a 72-tooth hub offers instant engagement to help you power through technical sections.
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 lightweight alloy rims showed a 29.6% improvement in puncture protection over previous generation alloy TR WheelSystems.
MORE TRACTION
The combination of wider alloy rims and the new 5mm thick sidewall design 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 alloy 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
Featuring race-proven durability and efficiency, the new TRA boasts a hollow 5mm wide rim edge design for added strength, a reduced risk of pinch flats, and lower tire pressure for more traction and control. Lightweight alloy rims and a 72-tooth hub help maximize power transfer and get you down the mountain faster.

WIDE GUARD TECHNOLOGY
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.

PUNCTURE PROTECTION
To simulate a pinch flat in the lab, a sharp, square-edged block is pressed against the tire until it hits the rim edge and punctures the tire. In test after test, the TRA WheelSystem was shown
Lab tests simulated pinch flat scenarios by pressing a sharp, square-edged block against the tire until it hit the rim edge and punctured the tire. In test after test, the TRA WheelSystem withstood the highest impact forces without flatting, outperforming previous generation TRA 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 21mm 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-TRA 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.
