The Shimano Ultegra R8150 Di2 rear derailleur is part of the Shimano Ultegra R8100 Di2 groupset. Shifting speed has increased by an impressive 58% in the Ultegra R8150 rear derailleur compared to previous Shimano Di2 derailleurs. And it has been optimised even further, especially to improve shifting under load. You'll feel this instantly when standing up on a climb or accelerating for a sprint. The Ultegra R8100 Di2 groupset is charged easily via the Shimano Ultegra R8150 Di2 rear derailleur with a charging cable which is also used for the new Shimano power meters. The junction box, which was previously mounted in the frame or handlebars, has become redundant. Its technology, with all the adjustment possibilities, has also been integrated into the rear derailleur.

Amazingly smooth gear changes. Make sure you update your levers’ firmware when cabled. Unfortnunately you can’t do this wirelessly, yet.
