The Kestrel 4000 Ultegra Triathlon/TT Bike is a carbon fiber, aerodynamic rocket ship that's the perfect means to blaze through the cycling leg of triathlons as well as your local time trial right out of the box. The Kestrel 4000 features a full 800K high modulus carbon frame and fork that are not only ultra-lightweight, but aero to the core. Kestrel's innovative rear triangle design all but removes the seat tube from the picture, not only shaving weight, but also placing the frame directly along the rear wheel for the ultimate airflow. The tapered head tube is highly beefed up where it meets the fork, down tube, and top tube creating a fairing effect on the front end that is also stiff and responsive.

The Kestrel 4000 Ultegra features an aerodynamic cockpit with an Oval Concepts 750 base bar and 750 clip-on aero extensions. Shimano Dura-Ace 2x11-speed bar end shifters ensure perfectly executed gear changes in the aero position with the Shimano Ultegra 11-speed derailleurs and cassette. An Oval Concepts 720 crankset is exceptionally stiff and lightweight plus features mid-compact 52/36T chainrings that are paired with an 11-28T cassette to ensure you have gearing options for a wide variety of terrain.

The Kestrel 4000 Ultegra rolls super-smooth on Oval Concepts 527 wheels that are equipped with Vittoria Zaffiro Pro Slick 700x23 tires. The Kestrel EMS Pro seatpost cuts an aero profile while the Prologo Zero Tri Pas saddle ensures you're comfortable throughout your triathlon or time trial effort.
