When it comes to pure XC climbing, acceleration and speed, nothing beats the efficiency of this lightweight composite hardtail. Engineered for pedalling stiffness, quick handling and the smooth, balanced ride of 29-inch wheels, it’s just the kick you need to move up through the pack.
When the terrain is fast and the climbs are steep, this is the race bike of choice for Giant XC pros like MTB Marathon World Champion Leo Páez. The XtC Advanced SL 29 boasts World Cup pedigree and a progressive frame design that achieves the lofty goal of being the lightest off-road machine ever built by Giant.
The chassis is handcrafted with pro-level Advanced SL composite, featuring geometry that’s optimised for its balanced, stable and fast-rolling 29-inch wheels. Every frame is custom assembled with a specific composite layup schedule that varies according to frame size. The result? Supercharged climbing efficiency, smooth compliance 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 off-road frame Giant has ever produced, offering serious XC racers a competitive advantage for climbing, accelerating and sprinting.
The frame is engineered with the highest stiffness-to-weight-ratio of any hardtail mountain bike in its class, which translates to ultra-efficient pedalling power and precise handling on the trail.
Each frame is custom-tuned based on its size. Individual composite lay-up schedules are created to optimise vertical compliance to produce a smoother ride quality on XC terrain.

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.
