The Shimano Dura-Ace DI2 12-speed Rear Derailleur RD-R9250 offers ultra-fast yet precise shifting. Even under medium to high loads, thanks to its low-profile design and Shimano Shadow+ technology, shifts are quick and quiet. There are no loud clunks or rattles with these high-tech components!
Despite its compact size, the rear derailleur houses the battery charging port and the wireless mode button. With just one cage length, the Shimano Dura-Ace DI2 12V RD-R9250 rear derailleur shifts on cassettes ranging from 11-28 teeth to 11-34 teeth, thereby increasing the versatility of this top-of-the-line Japanese groupset. The integrated carbon composite rear derailleur cage ensures maximum weight reduction.
