What is my size?

Share
Colombian XC racer Leonardo Páez rode his XtC Advanced SL 29 to a second-straight world championship title in 2020. To celebrate that achievement, we created this limited-edition replica hardtail frame with the highest stiffness-to-weight ratio of any bike in its class. Made with our most premium material, Advanced SL-grade composite, and weighing just 920 grams, it’s the lightest off-road frame Giant has ever produced.

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 professional-level Advanced SL composite, featuring geometry that’s optimized 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.

Key Performance Factors

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 pedaling power and precise handling on the trail.

    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.
