SHIMANO Ultegra Di2 rear derailleur RD-R8150 Shadow +
The compact Dura-Ace 8150 rear derailleur delivers lightning-fast yet precise gear changes. Even under medium and high loads, thanks to the low profile design and Shimano Shadow + technology, gear changes are quick and without any major noise. There is no noisy crashing or rattling with these high-tech components! Despite its slim dimensions, the rear derailleur houses the battery charging port and the wireless mode button. With just one cage length, the rear derailleur shifts on cassettes from 11-30 teeth to 11-34 teeth and thus increases the versatility of the top component group of the Japanese.
