With the mechanical 12-speed components of the 105 series, Shimano offers a shifting system for the most diverse types of road cyclists. The RD-R7100 rear derailleur combines the harmonious, consistent and nevertheless responsive shifting behavior of the Shadow RD design with Direct Mount compatibility and a wider ratio range. Depending on the selected crankset and cassette, the Top Normal rear derailleur also enables energy-saving transmission with a ratio of less than 1:1, which is ideal for climbing and supports the rider when climbing even steep ramps.

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.
