Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
XTC Advanced +
Give yourself more options for off-road adventures. This lightweight composite hardtail features 27.5+ wheels and tires for added grip and control on rugged terrain. As a bonus, you can convert it to a 29er for XC stability and speed.
Handcrafted with superlight Advanced grade composite, this versatile hardtail opens up a world of opportunity for off-road performance. In its 27.5+ configuration, you can run oversized tires for confident handling on rough and rowdy singletrack. It can also be transformed into a race-oriented 29er—or even a singlespeed setup*. The frame is designed with quick and stable geometry that’s optimized for a 120mm suspension fork. And it also features wider Boost hub spacing to improve wheel stiffness and maximize tire clearance. * Fork compatibility may vary. Please check with your local Giant authorized dealer.
Key Performance Factors
XC and trail efficiency
Advanced Composite frameset is superlight and laterally stiff, with engineered compliance for efficient climbing and acceleration on XC terrain.
XC/Trail Versatility
Option to use 29er wheel size for speed and stability, or 27.5+ for more rugged and adventurous terrain.
Off-road innovations
Tubeless Ready Giant WheelSystem, Boost hub spacing and 27.2 composite seatpost for compliance are all designed to improve off-road performance.
Techs & Features
Advanced Composite Technology
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.
