This pro peloton standout is the pinnacle of aero road. A killer in the sprints, with sublime overall ride quality.
Stiff enough to transfer power to the pedals, forgiving enough to keep you comfortable during long training efforts,
and it’s the most aerodynamic frame system ever developed—that’s Propel Advanced SL.
