Giant Anthem Advanced SL 0 29er Mountain Bike 2026

About this bike

Developed to help Giant pro Alan Hatherly win the 2025 Elite Men’s XCO World Championship this superlight XC composite flyer is engineered with a semi-integrated 120mm FlexPoint Pro rear suspension system and a flip chip to adjust geometry for any racecourse or XC terrain.
Key Performance Factors

TOTAL CONTROL
The new FlexPoint Pro suspension delivers 120mm of smooth active rear travel paired with a 120mm fork—helping you fly down rough descents and power up technical climbs. A flip chip lets you fine tune handling for all types of XC terrain. Superlight composite or alloy Giant WheelSystems (depending on model) with a next-generation 120-tooth helical ratchet drive system for immediate power and robust 5mm rim sidewalls for greater protection against impacts and punctures.


LOW-LATENCY SPEED CONCEPT
A fully reengineered composite frameset is 89 grams lighter than it predecessor with 7.95 percent greater stiffness-to-weight ratio (efficiency) to help you power up climbs and make every watt count. The WheelSystems and integrated handlebar/stem units are designed for maximum efficiency and instantaneous response to rider input. The rear shock is repositioned and semi-integrated with the top tube shaving weight and creating space for a second water bottle cage.


SYSTEM INTEGRATION
A new one-piece integrated handlebar/stem unit adds compliance to reduce shocks and vibrations improving control and hand comfort. It’s available in two models—the Contact SLR XC Integrated composite and Contact SL XC Integrated alloy. Both feature the same seamless cable routing and versatile sizing with a 780mm standard width and stem lengths ranging from 50-90mm.

Advanced SL Composite Technology

Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest stiffest and highest quality frames. This is the technology used by Giant’s pro racers in almost every cycling discipline.
OverDrive

Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Wide Guard Technology

When your wheel hits a sharp or square edge especially at speed pinch flats and rim damage can occur. Wide Guard technology minimizes this risk by broadening the contact point between the rim and tire with a solid 5mm rim sidewall. That means you can skip the heavy tire inserts to have less unsprung weight on your bike and allow your suspension to perform better. The wide sidewalls also better protect your wheel from big impacts reducing the possibility of rim damage.
MegaDrive

A massive rectangular downtube and oversized toptube work in unison to provide superior front end lateral and torsional steering precision. The precisely engineered rectangular shaped downtube yields unprecedented steering and pedaling stiffness.
Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
Advanced Forged Composite Technology
A state-of-the-art high-pressure moulding process is used to produce complex-shaped carbon fibre components that are lighter stiffer and stronger than similar components made from aluminium. This technology is used in critical performance parts such as Maestro Suspension rocker links.

FlexPoint Pro Suspension Technology

Developed as a superlight rear suspension setup for XC bikes that demand efficiency control and responsive handling FlexPoint Pro is a linkage-driven single-pivot system that delivers 100mm of rear-wheel travel. It’s engineered with a full-composite swingarm that significantly reduces overall frame weight.

Weight


The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight but in reality weight can vary based on size finish hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
