Shimano 105 RD-R7100 12 Speed Shadow RD Rear Derailleur - Black

Precise, quick-shifting 12-speed road rear derailleur

The Shimano 105 12-speed rear derailleur combines the smooth and stable shifting that is a staple of SHIMANO SHADOW RD design with direct mount compatibility and a wider gear range capacity.

The mechanism rear derailleur, SHIMANO SHADOW RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
