Giant XCA Disc Tubeless Wheelset

The XCA WheelSystem blends alloy strength with XC speed. With DBL technology, Wide Guard protection, and a precision helical ratchet hub, it delivers race-level performance with everyday reliability. Whether sprinting for position or powering through rock gardens, XCA gives you greater control and fast, efficient acceleration everywhere you ride.

Features
Dynamic Balanced Lacing (DBL): Enlarged hub flange boosts spoke bracing angles, increasing lateral, torsional, and transmission stiffness for more efficient power transfer and a planted ride feel.
Helical-Bevel Ratchet Drive System: A 10° helical engagement between hub and ratchet rings ensures efficient, consistent power transfer with reduced stress on components, while the 120-tooth ratchet delivers rapid 3° engagement for immediate response and precise power delivery.
Ratchet Wave Spring: Maintains even pressure between ratchet rings for consistent engagement and improved rolling efficiency.
Wide Guard Technology: Rounded-edge 5mm sidewalls reduce pinch flats and enhance rim impact protection.
30mm Inner Rim Width: Allows lower tyre pressures for improved traction and control.
