Super flexible outer cable housing for Shimano Dura Ace R9100, Ultegra R8000 and R7000 rear derailleurs.
Supplied with a polymer insert and long nose end cap to protect the polymer coating on Shimano 11 speed shift cables.
Normal SIS shift cable outer can be too stiff to allow the mechanical rear derailleurs to shift into the 11T sprocket - this cable along with the inserts will optimise your shifting and prolong the life of the polymer coating .
