Shadow RD

With its sophisticated technology, the Shimano Shadow rear derailleur is especially suited to a more aggressive riding style. The extremely minimized profile brings a number of advances. Due to its flat design and the construction based on single preload, the rear derailleur does not hit the chainstay even in the roughest conditions. The shifting works cleanly and quietly.
