This superlight pro-level aluminum material is made predominantly from 6011 alloy and delivers the highest strength-to-weight ratio of any Giant aluminum frameset. State-of-the-art microscopic grain manipulation and advanced butting allows for 20 percent thinner and lighter tube shapes than ALUXX SL framesets.
XtC SLR 29
All-Out XC
Hammer up climbs, accelerate on smooth singletrack, carry your speed as the trail dips and dives. This lightweight aluminum 29er combines efficiency and balanced control, just the right combination for XC performance.
Key Performance Factors
Lightweight acceleration
The lightest aluminum hardtail mountain bike frameset Giant has ever produced helps XC riders and racers climb and accelerate with speed.
Unyielding efficiency
With a best-in-class stiffness-to-weight-ratio, the all-new XtC SLR 29 sets the new standard for alloy-XC efficiency.
29er confidence and control
Larger 29-inch diameter wheels roll over rough terrain with balance and stability, giving you momentum on technical climbs and confidence on fast singletrack descents. Can fit up to a 2.4-inch rear tire.
Highlights
With its lightweight ALUXX SLR frameset and 29er-specific geometry, the XtC SLR 29 delivers fast, confident performance on XC trails and racetracks. Engineered to ride with a 100mm suspension fork, this smooth-riding hardtail accelerates with efficiency and makes quick work of the climbs. Here are the technologies that make this the lightest aluminum hardtail in our lineup.

Allux SLR
2
Optimized Tube Shaping
Our FluidForm process uses high-pressure fluid injection to shape and manipulate alloy frame shapes. This shaves weight while maintaining frame stiffness to improve ride quality on XC terrain.
3
Overdrive
Our original oversized fork steerer tube design features 1 1/2” lower and 1 1/8” upper headset bearings and a tapered steerer tube. The result is better steering stiffness for more precise handling on the trail.
4
Internal Cable Routing
Integrated ports and a tool-free bottom bracket guide in the frameset make cable installation easier. The internal routing of cables saves weight and creates a cleaner look.
5
Dropper Post Compatible
30.9mm seattube diameter and clean internal cable routing readily accepts dropper seatpost upgrades.
6
MegaDrive
A massive rectangular downtube forms the link between the OverDrive 2 headtube area and the PowerCore bottom bracket. This precisely engineered shape boosts steering and pedaling stiffness.
7
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 92mm wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
8
Giant Tubeless System
Factory equipped with tubeless ready rims and tires. Just add the included sealant and you’re ready to reap the benefits of added efficiency, control and flat protection in the most user-friendly and reliable system.
9
Boost Technology
Wider hub spacing (110mm front/148mm rear) results in stiffer wheels for added control. This also allows more tire clearance and creates an improved chainline for optimal drivetrain performance.
Techs & Features
ALUXX SLR Aluminum Technology
This superlight Pro level aluminum material is made predominantly from 6011 alloy and delivers the highest strength-to-weight ratio of any Giant aluminum frameset. State-of-the-art microscopic grain manipulation and advanced butting allows for 20 percent thinner and lighter tube shapes than ALUXX SL framesets.
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.
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.
