Brand New Giant XTC Advanced SL 1 Frameset – XL | Carbon Hardtail MTB

Up for sale is a brand new Giant XTC Advanced SL 1 Carbon Frameset in Extra Large size. This frameset was part of a complete bike that was immediately parted out right out of the box—it has never been ridden, never had a seatpost inserted, and is in pristine, unused condition.

Crafted using Advanced SL-grade composite, this frame offers top-tier stiffness-to-weight ratio for maximum efficiency. If you’re building a custom race-ready 29er, this is the ideal foundation.
