XTC Advanced SL 29 1

Light, efficient and flat-out fast. When the climbs are steep and the speeds are high, this is the weapon of choice for Giant's XC pros.

With World Cup pedigree and a progressive frame design, this is the lightest off-road machine ever built by Giant. The chassis is handcrafted with pro-level Advanced SL composite, featuring geometry made to optimise its fast-rolling 29-inch wheels. Every frame is custom assembled with a specific composite layup schedule that varies according to frame size. The result is supercharged climbing efficiency, smooth handling through roots, rocks and ruts and uncompromising performance to match your XC obsession.

Superlight and responsive: Pro-level Advanced SL composite frame is the lightest offroad frame Giant has ever produced, offering serious XC racers a competitive advantage for climbing, accelerating and sprinting.

Ultra-efficient: The frame is engineered with the highest stiffness-to-weight-ratio of any hardtail mountain bike in its class. This translates to ultra-efficient pedalling power and precise handling on the trail.

Custom compliance: Each frame is custom-tuned based on its size. Individual composite lay-up schedules are created to optimise vertical compliance and produce a smoother ride quality on XC terrain.
