Tecnologies
E-TUBE technology
E-TUBE is Shimano's “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and Shimano.
Shimano 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 chain stay in rough riding conditions. The result is smooth and silent performance.
Direct Mount Rear Derailleur
Rear wheels are easier to remove with a mounting option for SHIMANO SHADOW RD and SHIMANO SHADOW RD+. The direct mount feature is designed to suit a wide range of contemporary frames with large-section chainstays, in particular mountain bikes with thru-axle dropouts.
