XCR Carbon XC Wheelsystem | Rapid Response

Proven at the highest level by World Champion Alan Hatherly, the new XCR WheelSystem pushes the limits of what’s possible on fast, technical XC terrain. Engineered with advanced carbon construction, Dynamic Balanced Lacing (DBL) spoke technology, and a next-generation hub drive system, it combines the razor-sharp speed of an XC race wheel with the strength and control needed for full-speed, technical trail riding. From explosive starts to gnarly descents, XCR transmits every watt into forward motion, giving you the confidence to push harder, ride faster, and stay in control when it matters most.

Factores Clave de Rendimiento

FULL POWER

A lightweight carbon rim layup, high-tensile-strength carbon spokes, and Dynamic Balanced Lacing (DBL) deliver uncompromising race-day efficiency. This advanced spoke-lacing system sets the leading and trailing spokes at a wider bracing angle and balances their tension under power, creating a stiffer, more stable wheel structure that resists deflection when you accelerate or corner hard. Working together with the lightweight rim construction, this design achieves exceptional stiffness-to-weight. The result is explosive acceleration, razor-sharp handling, and greater control across fast, technical terrain. At just 1350g, the new XCR sheds 150g compared to the previous generation. Lateral stiffness-to-weight improves by 8.8%, boosting precision through corners, while rear transmission stiffness-to-weight increases by 26 % for more efficient power transfer.

ZERO DELAY

Every split second counts in XC racing, and this next-generation hub is engineered to deliver immediate, consistent power with every pedal stroke. At its core, the Helical-Bevel Ratchet Drive System creates a 10° helical engagement between the hub and ratchet rings. This angled, conical interface allows the ratchet teeth to mesh progressively rather than head-on, spreading load more evenly and maintaining constant contact through each engagement. The result is efficient torque transfer, reduced stress on components, and quieter operation under peak load. The 120-tooth helical ratchet system delivers 3° engagement for immediate reaction, ensuring instant power when accelerating. Together, these technologies deliver precise responsiveness and long-term durability, helping you maximize your speed and control on the most demanding XC terrain.

HIGH IMPACT RESISTANCE

Built to withstand the demands of modern XC racing and fast trail riding, Wide Guard Technology with reinforced hookless carbon rim construction delivers industry-leading strength and reliability. Rounded-edge 5mm better absorb impacts, reducing the risk of pinch flats, and a 30mm inner width supports lower tire pressures for more traction and control. Each XCR spoke features six carbon fiber tows, delivering increased strength and impact resistance over competitor designs with four tows. The result is exceptional durability and strength without added weight.

Tecnologías

Dynamic Balanced Lacing

Desde su introducción en 2015, Dynamic Balanced Lacing (DBL) ha sido la piedra angular de Giant WheelSystems. DBL asegura que los radios estén ajustados para una tensión óptima cuando están bajo carga dinámica, lo que resulta en una mayor durabilidad y eficiencia de pedaleo. El reborde del buje DBL agrandado también aumenta los ángulos de refuerzo de los radios, lo que aumenta la torsión / transmisión general y la rigidez lateral para una mejor transferencia de potencia y una carrera más estable.

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

El diseño de rueda Hookless mejora la durabilidad general, ofrece un ancho de llanta interior más amplio sin agregar peso adicional y también ayuda a crear una forma de neumático más redonda, que proporciona un agarre y manejo superiores, así como un mayor soporte de la pared lateral en las curvas. Además, sin el gancho de la rueda para "empujar" el talón de la rueda hacia adentro, el diseño de rueda Hookless ofrece un flujo de aire más fluido entre la llanta y la pared lateral de la llanta, lo que resulta en menor resistencia y un rendimiento aerodinámico mejorado en comparación con las ruedas con gancho estándar.

Tubeless System

Menos ponchaduras, mejor adhesión al camino. Una resistencia mínima para conseguir una conducción más precisa, más rápida. El sistema Tubeless de Giant te permite experimentar todos estos beneficios como nunca antes.
