Overview
About this bike
If you're aiming for a podium spot in Kona, your choice is clear: Kestrel's 4000. This wind tunnel-developed 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 shift unbelievably fast and precisely at the press of the buttons. The Oval Concepts aero bars and their Triathlon seat let you achieve the perfect aero tuck. Other niceties to help you smash your personal bests include the lightweight Oval Concepts stem, carbon base bar and aero TRP brakes.
