The revolutionary original 4000 introduced technology that had never been seen on a production bike before, and set the standard for carbon bikes for years to come. Continuing in this proud tradition, the modern 4000 is built specifically for the most demanding triathlon competitions, and it’s been proven time and again by top-level athletes, including Andy Potts-21-time winner of Ironman 70.3 races, 4-time USAT Triathlete of the Year, and former Olympian. For the 2015 model, Potts' valuable input during the design process made the 4000 even better. Proving its versatility, the 4000 has also been raced in time trials of the Vuelta a España and the Giro d’Italia. This is a dedicated machine for long-distance performance, made possible with details that make the rider more comfortable.
