Chaotic starts, the battle for position, red zone climbs and technical descents. XC racing is where adrenaline meets endurance, and this all-new superlight hardtail gives you just the kick you need to move up through the pack.When it comes to pure XC racing speed and performance, nothing beats the efficiency of a lightweight carbon hardtail. The new XtC Advanced SL 29 builds on its World Cup pedigree with a totally re-engineered frame that represents the lightest off-road machine we’ve ever built. The superlight chassis is handcrafted with pro-level Advanced SL carbon, featuring geometry that’s optimized for its balanced, stable and fast-rolling 29-inch wheels. Each one is custom assembled with a specific carbon 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 carbon frame is the lightest off-road 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, which translates to ultra-efficient pedalling power and precise handling on the trail.

Custom compliance

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

Technologies

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.

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.
