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.
Hammer up climbs, accelerate on smooth singletrack, carry your speed as the trail dips and dives. This lightweight aluminum 29er delivers efficiency and balanced control.
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 the momentum to tackle technical climbs and the confidence to fly on fast singletrack descents.
Highlights
With a frameset that’s engineered using ALUXX SLR, our highest-grade aluminum, this superlight and agile 29er delivers speed and efficiency for XC riders and racers. Designed to ride with a 100mm suspension fork, it’s a race-bred climber with quick acceleration. The 29er-specific frame geometry offers an ideal balance of stability and maneuverability on all types of XC terrain. Boost hub spacing gives you added tire clearance and wheel stiffness, and a new Giant WheelSystem with tubeless tires delivers a smoother, more efficient ride plus a reduced risk of flats.

ALUXX SLR ALUMINUM
OPTIMIZED TUBE SHAPING
Proprietary FluidForm process uses high-pressure fluid injection to shape and manipulate alloy frame shapes. This shaves weight while maintaining stiffness to improve the bike’s handling on XC terrain.
OVERDRIVE
Designed to provide precise front-end steering performance, this system’s oversized headset bearings (1 1/2” lower and 1 1/8”) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
INTERNAL CABLE ROUTING
Large cable ports and tool-free bottom bracket guide ensure easy cable installation while minimizing frame weight.
DROPPER POST COMPATIBLE
30.9mm seattube diameter and clean internal cable routing makes it easy to set up a dropper seatpost.
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.
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.
GIANT TUBELESS SYSTEM
Integrated Tubeless WheelSystem and tires delivers improved efficiency, comfort and control in the most user-friendly and reliable system.
BOOST TECHNOLOGY
Wider hub spacing (110mm front / 148mm rear) results in stiffer wheels for added control plus more tire clearance and 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.
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.

- WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
