Extensive CFD analysis and dynamic wind-tunnel testing were used to optimize every frame tube and angle in a process called AeroSystem Shaping technology. The frame is handcrafted using Advanced-grade composite material to produce a bike that’s lightweight and stiff, with a sharp, responsive ride quality. Disc brakes are integrated with the frame using flat-mount calipers, thru-axles and an asymmetric fork to maximize aerodynamic performance. From sprints to solo attacks, cornering and descents, the new Propel Advanced Pro Disc helps you slice through the wind and gain an advantage on the competition. Here's a look at its key technologies/
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
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.
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.
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.
Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
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. The wheels are integrated with Giant Gavia tubeless tires for added rolling efficiency and a reduced risk of flats.
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
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.
Contact SLR aero composite handlebar and Contact SL Aero alloy stem are designed to reduce overall drag while minimizing weight.
