The Propel Advanced Pro aero rocket is even faster at crucial moments. The redesigned frameset is more efficient at "cutting" air and is lighter than the previous generation. The result? Unmatched efficiency leading unerringly to victory.
AeroSystem Shaping technology, the result of CFD (Computational Fluid Dynamics) analysis and wind tunnel testing, optimizes aerodynamic performance at different angles of attack. The overall aerodynamic performance is further improved by the shortened elliptical frame tubes and the new Contact SLR/SL Aero cockpit.

The innovative OverDrive Aero steering system perfectly hides the bowden and guides it through the stem and head tube. This solution improves aerodynamic performance while allowing for quick and easy adjustment or replacement of cockpit components, as well as tuning the riding position for best performance.
Advanced Composite frames are manufactured using high quality materials and advanced construction methods and processes. As a result, they have high stiffness at low weight and provide excellent handling characteristics. Compared to the previous generation Propel Advanced Pro, the new one is even lighter for a better stiffness-to-weight ratio.
Founded in 1972, Giant is the largest bicycle manufacturer in the world.
Giant is the world's leading brand of high quality bicycles and cycling equipment. As part of the Giant Group, founded in 1972, the Giant brand combines craftsmanship, advanced technology and innovative design.
Giant has long been one of the leading innovators in cycling. They introduced lighter and stronger aluminium frames at a time when steel was the industry standard. They were the first to make carbon fibre bikes widely available to the world. They defined modern road bike design with Compact Road geometry. And the patented Maestro suspension revolutionized the full-suspension bike segment.

| Weight | Unfortunately, there is no standard for weighing bikes that all manufacturers adhere to, and the weights listed are often inaccurate. To find out the exact weight of a bike in a given size, you need to have the bike weighed at the store, as well as a model from a competing brand – this is the only way to get accurate figures for weight comparison.
