If you're looking for a triathlon bike dedicated to long-distance performance, look no further than Kestrel's 4000. Its high-modulus carbon frame employs radical design to deliver exceptional efficiency through targeted stiffness and aggressive aerodynamic sculpting of tubes and components. The 4000 Dura-Ace Di2 employs Oval Concepts’ ultra-aero 980 carbon wheelset and dreamy Vittoria Open Triathlon Evo tires to spin up quickly and minimize rotational mass to conserve energy and increase endurance. TRP 920 center-pull brakes feature intensely aerodynamic construction to slow you down when you ask them to and never when you don’t. Rotor's FLOW Aero crankset guest-stars in Shimano’s legendary Dura-Ace drivetrain, made even more impressive with Di2 electronic control for flawless shiftng so you can focus on your mental game, not fine-tuning your equipment. And, Oval Concepts and Prologo lend their considerable triathlon design expertise to provide all-carbon and titanium touch points that feel right, look right, and perform flawlessly, race after race, all the way to Kona.
