Anthem Advanced SL
The 2026 Giant Anthem Advanced SL is a dedicated cross-country race platform that shifts away from the steep, rigid feel of older XC bikes toward a more capable, modern 120mm-travel chassis. Developed alongside Giant’s World Cup program, the frame relies on a heavily revised FlexPoint Pro suspension layout. By moving the rear shock under the top tube, Giant centralized the bike's packaging and opened up the front triangle to accommodate two water bottles—a crucial update for marathon racers.
Positioned for privateers and elite athletes alike, the Anthem prioritizes a high stiffness-to-weight ratio and rapid acceleration. While it retains the sharp pedaling response expected of a flagship race bike, the increased travel and updated kinematics give it a broader operating window on technical courses. The platform also embraces modern integration, utilizing hidden cable routing and a one-piece cockpit on select models to maintain a clean, aerodynamic profile.

Fit and geometry
The Anthem’s geometry places the rider in an aggressive, forward-biased posture tailored for power delivery, driven by a steep seat tube angle and a moderate reach. However, the increased suspension travel raises the stack height slightly compared to older models, and a generous bottom bracket drop creates a distinct sensation of sitting inside the bike rather than perched on top of it. This lower center of gravity significantly bolsters cornering stability and high-speed descending control.
A two-position flip chip at the forward shock mount allows riders to fine-tune the handling. The stock High setting keeps the head angle at a sharp 67 degrees for precise steering on tight, twisty singletrack. Switching to the Low setting drops the bottom bracket further and slackens the angles by half a degree, favoring stability on steep, fast descents.
Fit adjustability is the primary tradeoff of the Anthem's modern design. The one-piece integrated bar and stem used across the lineup prevents riders from rolling the handlebars or easily swapping stem lengths. Additionally, Giant equips medium through extra-large frames with a 140mm dropper post, which aids descending freedom but requires a deep squat to fully compress.
Builds
Giant simplifies the Anthem lineup by using the exact same Advanced SL-grade carbon frame across all four builds, meaning entry-level buyers get the identical chassis and suspension kinematics as the flagship model. The range spans a wide price spectrum, with the primary differences coming down to drivetrain electronics, suspension dampers, and wheel materials.
The entry-point 2 build features a mechanical SRAM 12-speed drivetrain, Shimano SLX brakes, and alloy Giant XCA wheels. Stepping up to the 1 build introduces wireless shifting via a SRAM GX AXS Transmission and upgrades the rolling stock to Giant’s lightweight XCR carbon wheels, hitting a sweet spot for privateer racers.
The premium tiers focus on marginal weight savings and advanced suspension tech. The 0 build moves to a SRAM XX SL Transmission with an integrated Quarq power meter and RockShox Ultimate-tier suspension. At the top, the SE build commands a massive premium for a fully automated RockShox Flight Attendant suspension system and a wireless Reverb AXS dropper post, representing the absolute ceiling of current cross-country race technology.
Reviews
Reviewers consistently note that the Anthem Advanced SL successfully balances elite climbing efficiency with newfound descending composure. The revised suspension kinematics provide a firm pedaling platform, with testers observing "almost zero bob when seated" (Nminus1bikes) even when the shock is left fully open. This efficiency makes the bike eager on steep ascents, though some riders found the firmest suspension modes could cause the fork to deflect off sharp rocks on technical climbs.
Pointed downhill, the increased travel and revised shock tune transform the bike's character. The suspension is highly praised for its small-bump sensitivity, as trail chatter and mid-sized hits are "easily muted" (Mountain Bike Action) without blowing through the travel. This allows riders to maintain momentum and traction through rough sections that would stall older, shorter-travel race bikes.
While the integrated carbon cockpit limits adjustability, it surprised testers with its vibration damping. One reviewer noted the one-piece handlebar felt "very comfortable" (Bike Hub) and helped prevent hand fatigue on long descents. Overall, the consensus points to a machine that is "vastly more fun and capable" (Flow Mountain Bike) than its predecessor, trading a tiny bit of low-speed snappiness for immense stability and grip at race pace.
