The new Shimano Dura-Ace R9250 complete groupset, sold ready to install and ride. Now only wired where it makes the most sense: from the central multi-port battery to the front and rear derailleur, resulting in long battery life, complete reliability, and fast shifting performance. The drivetrain continues to use the classic Hyperglide+ technology, borrowed from Shimano's mountain bike kits to offer industry leading smooth shifting even while pedaling under load.
Included in the kit is a chain, crankset, front and rear derailleur, shift/brake levers, disc brake rotors, battery, Di2 wires, and a charging cable.
