Ultegra R8050 makes owning a Di2 bike more accessible. Shimano Di2 is an amazing feat of engineering. You never have to worry about chain rub because it self adjusts after every shift. Want to shift up or down just by holding a button? No problem plug it into a computer and programme it to shift exactly how you want it to. Slick, light and durable you’ll never want to ride mechanical again.
