Shimano 105 R7000 SS Shadow rear derailleur

Rear derailleur. The RD-R7000 rear derailleur features Shimano’s Shadow RD design, which gives the derailleur a lower profile and more stable operation.
Coming with the high-end aesthetic and race characteristics of its Dura-Ace and Ultegra big brothers, the new 105 series also considers that most riders will use their bikes for purposes other than competitive racing. 105 is Shimano’s first level 11-speed groupset for those who are seriously committed to road bike riding, but that definition now becomes broader with the inclusion of superior handling and adaptable control to master different riding situations.
