Kestrel has totally reworked their Airfoil and Talon framesets after spending hours in the wind tunnel and stress lab testing everybody’s frames. Different layups, better carbon, more beefy downtubes and bottom bracket clusters make for lighter yet 20% stiffer frames. They also have a new two position aero seatpost on both frames, which now gives all sizes of Airfoil the ability to go to 80+ degrees. The new versions also sport some pretty spiffy, motorcycle-influenced paint jobs. The airfoil is a great frame for those with shorter legs and longer torsos, or those with a normal build who like a very aggressive drop. This is due to the airfoils low stack and long reach measurements.
