2011 Kestrel Airfoil Pro SL Triathlon Bike Bikes & Frames Tri & Time Trial bikes

2011 Kestrel Airfoil Pro SL Triathlon Bike. The 2011 edition of the Kestrel Airfoil Pro SL Triathlon Bike is definitely as fast as it looks. From its radically sleek, seat tube less carbon fiber frame, to the Oval W745 carbonalloy clincher wheels with 45mm deep aero rims, this bike has speed written all over it when it comes to triathlons or time trials. Kestrel's designers sealed the deal with a Profile Design CX3 integrated aero bar, Shimano Ultegra 2x10 speed drivetrain, Dura Ace bar end shifters, and great handling Vittoria Rubino Pro II tires. Note: The 47cm and 50cm size frames both utilize 650c wheels.
