Giant Propel Advanced Pro 1 Disc 2021 - Road Bike
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 optimize the technology.
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 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.
