When you’re unsure what lies ahead—smooth roads, gravel or dirt—and you relish the adventure of quiet backroads, this is the bike. With its lightweight aluminum frame, drop handlebars and rugged, high-volume tires, you’re ready for anything.
Your ride doesn’t end when the pavement ends. That’s when things start to get fun. A lightweight ALUXX SLR aluminum frame, smooth-handling composite fork, and drop-bar positioning make ToughRoad SLR GX the right choice for rolling into the unknown. The smooth-rolling 700c wheels are fitted with high-volume Giant tubeless tires, which allow you to run lower tire pressure for comfort and traction plus a reduced risk of flat tires. The D-Fuse seatpost absorbs road vibration to help minimize fatigue on long rides. And powerful disc brakes with 160mm rotors give you added confidence and control on rough roads and in all types of weather. Thoughtful details including integrated rack mounts and the X-Defender downtube complete the package, making ToughRoad SLR GX the perfect machine for tackling imperfect roads.

Technologies & 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.
D-Fuse Technology
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.
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.
