The aero road choice of Giant Pros including Marcel Kittel.
Designed in the wind tunnel, proven at the Tour de France.
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.
Add technologies including the SpeedControl SL brake system,
integrated seatpost and internal cable routing and the result is clear:
Propel Advanced SL is faster from every angle.
