If you're aiming for a podium spot in Kona, your choice is clear: Kestrel's 4000 SL Ultegra Di2. This wind tunnel-developed, Kestrel 800K ultra high-modulus carbon missile is light, efficient and super aerodynamic. It boasts a finely tuned airfoil profile with wing-like tubes and a seat tube so minimal it almost disappears. Plus, Kestrel's tapered EMS Pro SL TT aero carbon fork integrates into the down tube making the 4000 almost invisible to the wind, while the internal cables, hidden aero rear brake and Kestrel's EMS aero seatpost help eliminate drag. Oval's deep-dish carbon wheels with fast-rolling Vittoria tires make this wind-cheater even more aero, while Shimano's electric-shifting Ultegra Di2 drivetrain with Vision's Trimax crankset provides unbelievably fast and precise shifting at the press of the buttons. You'll also love the Oval Concepts aero bars and their Triathlon seat that let you achieve the perfect aero tuck. Other niceties to help you smash your personal bests include the lightweight Oval Concepts stem and carbon base bar.
