Shadow RD
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 chainstay in rough riding conditions. The result is smooth and silent performance.
