2025 Giant Anthem Advanced SL 0

2025 Giant Anthem Advanced SL 0

The 2025 Giant Anthem Advanced SL 0 is the pinnacle of the Anthem lineup — the very platform developed to help Giant pro Alan Hatherly claim the 2025 Elite Men’s XCO World Championship. This is the top-spec build, upgrading to SRAM XX SL Eagle Transmission with an integrated Quarq power meter, RockShox Sid Ultimate fork and shock, and SRAM Motive ULT hydraulic brakes — everything dialed to the absolute maximum for riders who demand the best.

The fully reengineered Advanced SL composite frameset is 89 grams lighter than the previous generation with a 7.95% improvement in stiffness-to-weight ratio. Every component, from the integrated carbon cockpit to the carbon-spoked Giant XCR WheelSystem, is chosen to make you faster.
