SIS OT-RS900 shift outer casing

The SHIMANO SIS OT-RS900 rear mech outer casing reduces friction on the inner cable. To improve smoothness of operation, the polyethylene casing with a Ø of 4 mm is already greased with a silicone grease. This allows for faster and smoother gear changes. This cable casing is required when using a Dura Ace RD-R9100 rear derailleur.
