Shadow RD
With their sophisticated technology, Shimano Shadow RD rear derailleurs are especially intended for more aggressive riding style. Their super low profile design carries many benefits. Thanks to the low profile and a single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
