Giant XCR Disc Tubeless Wheelset

Lightweight, efficient, and stronger than ever, the XCR WheelSystem is built for today’s XC racing and beyond. With advanced carbon construction, DBL technology, and a next-generation hub system, it delivers explosive acceleration, precise handling, and proven World Championship performance on technical XC terrain

Features
Dynamic Balanced Lacing (DBL): Enlarged hub flange increases spoke bracing angles, balancing tension for superior lateral and torsional stiffness and more efficient power transfer.
High-Tensile-Strength Carbon Spokes: Six-tow carbon construction delivers up to 3× the impact resistance of standard designs while maximizing stiffness-to-weight for rapid acceleration.
Optimised Reinforced Layup: Strategic carbon placement enhances strength and stiffness while minimising weight for uncompromising race-day efficiency.
Helical-Bevel Ratchet Drive System: A 10° helical engagement ensures efficient, consistent power transfer, while the 120-tooth ratchet delivers rapid 3° engagement for immediate response and precise power delivery.
Ratchet Wave Spring: Distributes even pressure for smoother engagement and improved rolling efficiency.
Wide Guard Technology: 5mm rounded-edge rim sidewalls provide superior impact protection and reduce pinch flats.
30mm Inner Width: Supports lower tyre pressures for more traction and control.
