Kestrel 4000 Road Bike - 2016 Shimano 105. When it's you against the clock, you need a bike that can bring out your very best. The 2016 Kestrel 4000 105 bike features a full 800K hi modulus carbon frame and fork that is not only ultra light weight, 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 headtube 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 4000 105 also features a drivetrain that is more than raceworthy. An Oval Concepts 520 crankset is ultra stiff and light, and features a compact 50/34 chainring setup giving you optimal potential to maintain high speeds while still powering up climbs. Shimano 105 5800 derailleurs couple perfectly with Microshift BS-A11 bar-end shifters to promise you 11-speed shifting easy with 22 gearing options to keep you dialed in whatever the situation. In the cockpit the 4000 105 features Oval Concepts 750 aero bars with a 750 clip on extension opening the rider up to the most aero, aggressive riding position that also stays comfortable for the duration. An Oval Concepts 313 alloy stem keeps the front end light and responsive, and Prologo NAGO Evo Tri40 TT saddle is designed to keep you aero and comfortable in the saddle so you can focus on the task at hand without worrying about fatigue. An excellent value for a full carbon Ultegra bike, the 4000 Ultegra is an easy choice for riders who demand great performance for training or racing, or who want an unquestionably high-end platform for a customizable tri/time trial bike that will take you immediately to the next level.
