Giant and Liv have unveiled the latest iterations of their flagship aero road bikes—the Propel Advanced SL and the EnviLiv Advanced SL—both engineered to deliver exceptional speed, reduced weight, and enhanced aerodynamic performance.
Giant Propel Advanced SL: A New Benchmark in Aero Performance
The Propel Advanced SL has undergone significant refinements, resulting in a frame that is 355 grams lighter than its predecessor. This weight reduction, combined with aerodynamic enhancements, equates to an 18.4-watt advantage, translating to a 72-second gain over a 40 km course at a speed of 40 km/h. (cyclingonline.nl)
Central to these improvements is Giant’s “Total Speed System,” which focuses on the seamless integration of the rider, frame, cockpit, and wheels. This holistic approach led to the development of a fully dynamic wind tunnel mannequin, produced via 3D printing, to accurately analyze the aerodynamic interaction between the cyclist and the bike.

Key Features of the Propel Advanced SL:
-
Integrated Cockpit: The new Contact SLR Aero Integrated cockpit features a flattened rear and a narrow top profile, minimizing air resistance and enhancing control. (bikeradar.com)
-
CADEX Max 50 Wheels: Equipped with 50 mm hookless carbon rims, these wheels are paired with CADEX Aero tires and Giant Gavia Course tires, optimizing the tire-to-rim interface to reduce drag without compromising grip and efficiency. (cyclingonline.nl)
-
OverDrive Aero Technology: This system incorporates a D-shaped steerer tube and fully internal cable routing, contributing to a cleaner airflow and improved handling precision. (giant-bicycles.com)
Liv EnviLiv Advanced SL: Designed for Women, Engineered for Speed
The EnviLiv Advanced SL is tailored for female cyclists seeking top-tier performance in both races and group rides. This model boasts a 120-gram weight reduction and an 8.6-watt aerodynamic advantage over its predecessor, achieved through meticulous design and component integration. (cyclingonline.nl)
Key Features of the EnviLiv Advanced SL:
-
Optimized Aerodynamics: Featuring truncated ellipse airfoil tube shapes and the Liv Contact SLR Aero handlebar with deeper drops and flattened tops, the EnviLiv reduces drag and enhances control. (giantnorthlakes.com.au)
-
Advanced Composite Frame: Utilizing Continuous Fiber Technology and Carbon Nanotube Technology resin, the frame offers increased strength without added weight, resulting in a 19% improvement in the stiffness-to-weight ratio. (endurancesportswire.com)
-
Vector Integrated Seatpost: This design reduces mass and improves vertical compliance, contributing to a smoother ride without compromising power transfer. (endurancesportswire.com)
-
OverDrive Aero Technology: Similar to the Propel, the EnviLiv incorporates this system for enhanced aerodynamic performance and handling stability. (giantnorthlakes.com.au)
