The 2014 Giant Propel Advanced SL 0 is a purpose-built aero road bike designed to slice through the wind and hold speed with authority. Crafted from Giant’s top-tier Advanced SL-grade composite and shaped using AeroSystem technology, the frame blends stiffness, light weight, and aerodynamic efficiency in a sleek, integrated package. It comes race-ready with Shimano Dura-Ace Di2 electronic shifting, Zipp 404 Firecrest carbon wheels, and Giant’s proprietary SpeedControl SLR brakes. The one-piece carbon Contact SLR cockpit and integrated seatmast further reinforce its wind-cheating profile, making it an ideal choice for riders chasing marginal gains and aggressive performance on the road.
