Defeat your biggest rival — air resistance — in every ride and race with Giant’s Propel Advanced SL 1. 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-refined tube shapes, an integrated seatpost, and tucked-in brakes that propel you toward the finish line. 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 top-end Dura-Ace gruppo offers impeccable shifting. Super fast, ultra-light Zipp 404 Firecrest wheels and a Contact SLR bar and stem complete the aero package, resulting in one incredibly light, impressively fast ride.
