Kestrel 4000 Road Bike – 2016 Shimano Dura Ace Di2
Kestrel 4000 Road Bike – 2016 Shimano Dura Ace Di2. Peak performance demands peak technology. The Kestrel 4000 Dura Ace Di2 road bike is a tri/TT bike that makes sure you put your best against the clock. If you need a bike that won’t compromise on any spec and that will take you to your limit when it comes to speed, then this is the bike for you. Shimano Di2, Oval deep dish carbon wheels and Kestrel’s proprietary carbon technology combine to take every watt you produce and convert it into miles per hour. With 20 years of carbon fiber experience, Philadelphia’s Kestrel brand bicycles is truly a leader and innovator of race design against the clock. Behind every Kestrel stands a mighty process: meticulous engineering, modeling, computer-simulations and prototypes, subjected to rigorous structural testing, test-ridden, refined and redesigned. Finally, each frame is hand built by Kestrel using the tightest quality control standards in the industry before the bike reaches the Performance Bicycle sales floor, or is delivered to your door from our warehouse. The Kestrel 4000 LTD is constructed from 800k High Modulus (high degree of stiffness) carbon, which is 30% more stiff than their 700k carbon, and allows Kestrel to use 20% less material in the production of the frame. The BB30 press fit bottom bracket and tapered head tube further the amount of frame stiffness. The 4000 LTD is a dormant rocket ship, begging for even a small effort, and it will takeoff. Shimano Dura-Ace 9070 11-speed Di2 is more than a mouthful; it’s the preferred weapon against the clock. With Dura-Ace 9070, Shimano moves to the next generation with authority. Reduced shifting effort lets you concentrate on riding. There’s more control thanks to improved ergonomics and the unbeatable reliability and durability should give you every bit of confidence. The Shimano Di2 9070 rear derailleur delivers precise, lightning-fast shifts across the Dura-Ace 11-speed cassette, whatever the conditions, with just a button click. The 9070 rear derailleur is now more compact and lighter. Plus, automatic crash protection moves the cage out of harm’s way. The 4000 LTD features Di2 TT shifters. The Quick, double-button, effortless electronic push button shifting on the aero bar extensions allows for quick-thinking when the course or grade suddenly changes. A standard 53/39 Rotor FLOW Crankset was chosen to deliver massive amounts of power directly into the frame and improve aerodynamics. Together, these components minimize weight to maximize your overall performance. Oval Concepts 980 Carbon Clinchers, like the Zipp Firecrest Carbon 808 wheel set, feature an 80mm rim height for increased aerodynamics. The 980’s are ultra-stiff, responding well to sudden accelerations and outfitted with low rolling resistance Vittoria Open Corsa Evo CX 23c tires. The Kestrel 4000 LTD with Shimano Dura-Ace Di2 9070 has everything you could need to beat the clock.
