From pro-level XC race bikes to confident trail tamers, the 2025 Giant XTC Advanced SL 29″ is a lightweight frame with a focus on ride quality. Each one is purpose built for the way you ride, whether that’s blasting berms, gunning for KOMs, or just beginning your singletrack MTB adventures.

Advanced SL Composite Technology

Professional Grade raw carbon fiber is woven in Giant’s composite factory to produce their 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.

Features:

• Frame – Advanced SL-grade composite, 12x148mm thru-axle
• 2.25″ max tire size
• 38t max chainring size
