Super sleek and undeniably aerodynamic, Giant’s Propel Advanced SL 0 is the ace up your sleeve, ready to cheat the wind at all times, from every angle. Honed in the wind tunnel and constructed from Giant’s Advanced SL-Grade composite, this rocket is destined to increase your speed. The frame boasts heavily-tested tube shapes, an integrated seatpost, integrated aero bar/stem combo and hidden, tucked-in brakes. Balancing aerodynamics with ride quality and rigidity, the Propel’s beefy bottom bracket delivers stiffness where you need it and the oversize steerer ensures pinpoint cornering, while Shimano’s electronic Dura-Ace Di2 groupset offers perfect shifting. Featherweight and invisible-to-the-wind Giant SLR 0 Aero wheels complete the aero package, resulting in one incredibly light, wind-cheating ride.
