Shimano Ultegra Di2 2x11 

The P-Series is for the athlete seeking speed, storage, value, and comfort. It’s our no-nonsense machine engineered to get you from A to B as fast as possible. It’s a no-excuses machine and your perfect PR sidekick. It’s lighter and more aero than its predecessor, the P3, making it faster on all courses. Naturally, aerodynamics and weight are only part of the equation—the P-series comes with a 500mL aero bottle, 400mL of top tube storage, and an integrated rear hydration mount. Customize the cockpit and the storage to your needs and your race.
