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.

Key Performance Factors

Superlight & Responsive

Professional-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.

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.

Custom Compliance

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

Highlights

From its superlight composite frameset to its XC-specific race geometry, the XtC Advanced SL 29 World Champion Edition helps you aim for the podium with efficiency and speed. Here’s a look at the key technologies behind this proven winner.

Techs & Features

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.

MegaDrive

A massive rectangular downtube and oversized toptube work in unison to provide superior front end lateral and torsional steering precision. The precisely engineered, rectangular shaped downtube yields unprecedented steering and pedaling stiffness.

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.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
