Giant Tra 29inch Boost 6b Disc Tubeless Hookless Mtb Rear Wheel

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.Highlights: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 Wheel System 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 Wheel System 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 Wheel System 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.Features:- Innovative Wide Guard technology drastically reduces pinch flats and offers superior impact protection without the need for heavy tire inserts. - A 30mm inner rim width and 5mm rim sidewalls allow lower tire pressures for better traction and control.- 72-tooth pawl driver and oversized internals for instant engagement and superior durability.- Robust and lightweight alloy rim construction with hollow rim sidewalls.Specifications:- Rim Material: Alloy- Rim Type: Hookless- Tubeless: Giant Tubeless System (Rim Tape and- Valve Kit Included)- Rim Depth: 21mm- Rim Outer Width: 40mm- Rim Inner Width: 30mm- ETRTO: 622x30- Rear Hub: TRA HE, Alloy, 72T Pawl Driver, 6 Bolt- Hub Compatibility: Shimano HG / MS, SRAM XD- Bearing: Sealed Cartridge- Rear Axle: 148x12, Boost, Thru Axle- Rear Spokes: Sapim Laser- Rear Lacing: 28H, DBL, Straight Pull- Nipple Type: Sapim Double Square- Rear Weight: 1,048g (29) / 1,015g (27.5) without tape/valveTechnology: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.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.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.
