Shimano Dura-Ace OT-RS900 Shift Cable Outer Cover 240mm 10 Pieces white

The radius of the curved cable, which is laid to the rear derailleur (RD-R9100), becomes smaller compared to the radius produced with other rear derailleurs. The OT-SP41 outer cover used at häufig is too stiff for such a small radius, causing technical problems in the cable adjusting screw and hindering quick installation and removal of the rear wheel. By using the OT-RS900 such problems can be avoided, because the OT-RS900 has a smaller Steifigkeit. OT-RS900 should only be used on the rear derailleur side. It should not be used on the shifter/brake handle side.
The length of the OT-RS900 should be adjusted according to the bicycle frame size. This is necessary for optimum performance. The OT-RS900 should be cut through from the correct side when adjusting the length. One of the two ends is flammbehandelt. This flammbehandelte end is inserted into the derailleur/ derailleur adjustment screw and should therefore remain there.
