This composite road machine offers a true advantage for sprinting and solo riding. With its aero-engineered frameset, integrated WheelSystem and disc-brake technology, you have a new level of efficiency and road handling to help you aim for the podium.
Meticulously developed for best-in-class aero road performance, this razor-sharp road racer was born to sprint, chase or make your attack. The frame is handcrafted using Advanced-grade composite material to produce a bike that’s lightweight and stiff with a responsive ride quality. The components are as integrated as they can possibly be, with smooth lines from the handlebar and stem, internal cable routing, and a WheelSystem that uses a 65mm deep rear rim for maximum aero performance and a shallower 42mm front for added control. Even the disc brakes are integrated into the frame, with flat-mount calipers and thru-axles designed to optimise the technology.
Key Performance Factors
Integrated aerodynamics
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR/SL Aero cockpit produce the best overall aero performance.
Total control
Integrated disc brakes deliver smooth, powerful control and modulation for added confidence in all conditions. Flat mounts and thru-axles boost stiffness and improve overall handling, and an integrated WheelSystem with a 65mm rear rim and shallower 42mm front rim optimises aerodynamics and control.
Unrivaled efficiency
Advanced-grade composite frameset features high-performance materials and Giant manufacturing processes for optimised stiffness and the lowest weight in its category.

Aerosystem Shaping Technology
2
Vector Seatpost
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
3
Advanced Composite Frame
High Performance Grade raw carbon fiber and Giant’s proprietary resin formula is used to produce custom composite material in our own composite factory that is extremely lightweight, stiff and compliant.
4
OverDrive 2
Giant’s most advanced steerer tube technology offers unprecedented steering precision. Oversized headset bearings (1 1/2” lower, 1 1/4” upper) and a tapered steerer tube produce superior front-end stiffness.
5
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
6
Giant WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this composite SLR Aero WheelSystem features different rim depths front and rear to minimize drag without compromising stability. The rear has a 65mm rim for uncompromising aero performance and power transmission. The front has a shallower 42mm rim for added control in crosswinds.
7
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
8
Disc-Brake Integration
The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.
9
Aero Bar and Stem
Contact SLR aero composite handlebar and Contact SL Aero alloy stem are designed to reduce overall drag while minimizing weight.
Techs & Features
Advanced Composite Technology
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.
AeroSystem Shaping Technology
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
OverDrive 2
The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme 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.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
