Some roads are smooth, others are rough. This smooth-riding all-rounder handles it all, taking you from the main route to more adventurous options with confidence and control.
Key Performance Factors
Balanced road geometry
Frame is specifically engineered to produce a balanced, all-rounder feel that blends confident rider positioning with agile cornering and acceleration.
Smooth ride quality
Innovative D-Fuse seatpost reduces road shocks and vibrations, and a Giant WheelSystem lets you run tubeless tires up to 38mm for a smoother ride quality and reduced risk of flats.
Total control
Seamless disc brake integration, including flat mounts and 12mm front and rear thru-axles, produces more consistent braking power for better control, even in wet weather and on rough roads.
Techs & Features
ALUXX Aluminum 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.
Compact Road Design
Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
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.
D-Fuse Seatpost
The proprietary “D” shaped composite seatpost damps vibration, resulting in a smooth, compliant ride.
