The Giant Anthem Advanced SL 1 is designed to deliver maximum efficiency on modern XC courses. The Advanced SL-grade composite frame uses a fully reengineered layout that’s lighter and stiffer than the previous generation, helping every pedal stroke translate into forward motion.
FlexPoint Pro suspension delivers 120mm of active rear travel while keeping weight low and efficiency high. The floating pivot design stays active under pedalling and braking, offering traction and control on technical climbs and rough descents. A flip chip lets you fine-tune geometry to suit different terrain or riding styles.
Up front, the RockShox SID Select+ fork and matching SIDLuxe Select+ rear shock provide controlled, responsive suspension. Both are tuned for XC racing and feature remote lockout, making it easy to switch between fully open and firm settings as the trail changes.
Wireless SRAM GX AXS shifting keeps the cockpit clean and delivers precise gear changes under load. The wide 10–52T cassette gives plenty of range for steep climbs without sacrificing top-end speed. Shimano Deore XT brakes offer strong, reliable stopping power with good modulation for technical sections.
The integrated carbon handlebar and stem improve front-end stiffness while adding compliance to reduce hand fatigue on longer rides. Lightweight Giant XCR wheels and fast-rolling Maxxis Aspen tyres round out a bike that feels quick to accelerate, stable at speed and confident when the trail gets rough.
The Anthem Advanced SL 1 is a focused XC race bike that rewards smooth, efficient riding and delivers the control needed to push hard on modern cross-country trails.
