Giant Anthem Advanced SL 1 Mountain Bike in Rainbow Black

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.

The 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 allows for fine-tuning handling for all types of XC terrain. The bike features superlight composite Giant WheelSystems 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.

A fully reengineered composite frameset is 89 grams lighter than its predecessor, with 7.95 percent greater stiffness-to-weight ratio to help you power up climbs. The WheelSystems and integrated handlebar/stem units are designed for maximum efficiency and instantaneous response. The rear shock is repositioned and semi-integrated with the top tube, shaving weight and creating space for a second water bottle cage. A one-piece integrated handlebar/stem unit adds compliance to reduce shocks and vibrations, improving control and hand comfort. It features seamless cable routing and a 780mm standard width.

Features:

• Advanced Forged Composite Technology: High-pressure moulding process for complex-shaped carbon fibre components that are lighter, stiffer and stronger than aluminium.
• Advanced SL Composite Technology: Professional grade raw carbon fibre woven to produce Giant's lightest, stiffest and highest quality frames.
• FlexPoint Pro Suspension Technology: Linkage-driven, single-pivot system delivering 100mm of rear-wheel travel with a full-composite swingarm.
• OverDrive: Oversized fork steerer tube technology with 3.8cm (1 1/2") lower and 2.9cm (1 1/8") upper headset bearings for precise steering.
• PowerCore: Oversized bottom-bracket/chainstay area with a 92mm wide bottom-bracket design for off-road bikes.
• MegaDrive: Massive rectangular downtube and oversized toptube for superior front end lateral and torsional steering precision.
• Wide Guard Technology: Broadens the contact point between the rim and tyre with a 5mm rim sidewall to minimise pinch flats and rim damage.
• Tubeless System: Fewer flat tyres, greater traction, less rolling resistance and a smoother ride.
