TRA WheelSystem
Factory Fun
Proven under the most demanding conditions by Giant Factory Off-Road Team racers, the TRA WheelSystem is now available in 24” and 26” options for smaller rippers. Alloy rims with hollow-construction 5mm rim walls beef-up impact protection but keep weight low for better suspension performance. The wide rim walls also reduce pinch flats and allow lower tire pressure for more traction and control. Out back, a durable 72-tooth freehub helps maximize power transfer for more speed and more fun.
Key Performance Factors
DAMAGE CONTROL
When your wheel hits a sharp or square edge, especially at speed, pinch flats and rim damage can occur. New Wide Guard Technology minimizes this risk by broadening the contact point between the rim and tire with a super-strong 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. Wide sidewalls also better protect your wheel from big impacts, reducing the possibility of rim damage.
GAINING TRACTION
A broad 30mm inner rim width and 5mm sidewalls allow you to run much lower tire pressure for better traction and control. Add in a low 21mm rim depth for better compliance, and the TRA lets you blast the roughest terrain.
POWER MOVES
The lightweight, durable alloy and hollow rim walls combine with an industry-leading 72-tooth pawl driver for rapid power transfer and instant engagement. On the rear hub, an oversized drive-side hub body bearing, axle and ring nut combine with enlarged pawls to increase stiffness and further maximize 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.
