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.

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.

重點特色

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.

科技新知

DBL動態平衡編輪

DBL動態平衡編輪技術自2015年問世以來,便一直是GIANT輪组系統的核心技術。DBL動態平衡編輪技術的應用,使騎士開始踩踏後,輪组幅條張力將會在動態中取得平衡,提升輪組傳動剛性及騎乘效率。

寬護技術

當輪組在越野騎乘狀態下高速撞擊到尖銳或方形塊邊緣時,有可能發生內胎夾傷(俗稱蛇咬)和輪框損壞的狀況。 加寬輪框防護結構的寬護技術 (Wide Guard technology) 通過提供堅固的 5 mm輪框側壁,擴大了輪框與外胎之間的接觸點,從而將這種風險降到最低;同時,寬側壁也能更好地保護您的輪組免受巨大衝擊,減少輪框損壞的可能性。

無框鈎輪圈設計

GIANT以創新的製造工藝消除了框鈎,特殊的製程創造出連續碳纖維結構,不像傳統有鈎輪圈在成型時需另外挖出輪圈框鈎,可大幅提升輪組的耐用性及抗衝擊性。且無鈎輪圈能讓外胎在安裝充氣後有更佳的成型輪廓,使外胎提供更出色的抓地力和操控性,並在過彎時提供更好的側向支撐性。
