Giant Propel Advanced SL Frameset (2014)

Proven through third-party wind-tunnel tests to be more aerodynamic from every yaw angle tested when compared to other leading aero road bikes, Propel Advanced SL sets a new standard for speed. The Advanced SL-grade composite frame is engineered with AeroSystem Shaping Technology, which saves 12-36 seconds over a distance of 40km at a speed of 40 kph compared to key aero bike competitors-with zero compromises in weight or stiffness. And technologies including the SpeedControl SLR brake system, integrated seatpost and internal cable routing, and the result is clear: Propel Advanced SL is faster from every angle.
