Whether speeding to new personal bests or climbing to the top of the podium, Kestrel's 4000 Pro SL is the bike to make it happen. 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. There are internal cables and also a hidden aero rear brake and Kestrel's EMS aero seatpost, too. This slippery sled rolls on quality Oval Concepts wheels with fine Vittoria tires and you get a hill-flattening Oval Concepts/Shimano 105 20-speed compact drivetrain and trick TRP aero brakes. 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 fly along at warp speed include the precision Microshift shifters and lightweight Oval Concepts stem and base bar.
