Shimano Dura-Ace R9100 OT-SP41 Optislick Road Shift Cable Set cassons 14T lower) – smooth chainThe Shimano shift cable set OT SP41 OT RS900 Polymer is suitable for Dura Ace R9100 and Ultegra R8000, among others, because here the rear derailleurs have to be mounted on the bike with the special OT RS900 cable housing. The standard OT SP41 cable housing cannot be used as it is too stiff for the small radius required. Also included in the set are shift cables with a polymer coating that looks like tubes wrapped around the cable under a microscope.
