Shimano shift cable housing OT-RS900 for modern 11-speed Road rear derailleurs - 10 pack
The Shimano OT-RS900 shifter cable housing must be used in current Road and Gravel rear derailleurs such as Dura Ace RD-R9100, Ultegra RD-R8000, 105 RD-R7000 and others, as the cable between the frame and the rear derailleur is routed with a smaller radius. The standard OT-SP41 cable housing is too stiff for this purpose. Ten OT-RS900 cable housings, each 240 mm long, are supplied.
Diameter: 4 mm
Length: 240 mm
Recommended Cable Diameter: 1.2 mm
- pre-lubricated with special silicone grease to ensure smooth shifting
Modern Shimano 11-speed Road rear derailleurs, such as Dura Ace RD-R9100, Ultegra RD-R8000 and 105 RD-R7000, must be mounted on the bicycle with the special OT-RS900 cable housing. The radius of the curved cable that is routed from the frame to the rear derailleur is smaller here compared to the radii produced by other rear derailleurs. The frequently used OT-SP41 cable housing is too stiff for such a small radius, causing technical problems in the tension adjustment screw and hindering quick installation and removal of the rear wheel.
By using the OT-RS900 such problems can be prevented, because the OT-RS900 has a lower stiffness. The OT-RS900 should only be used on the rear derailleur side and not on the shift/brake lever side.
Note from the manufacturer: The length of the OT-RS900 should be adjusted according to the bicycle frame size. This is necessary for optimal performance. The OT-RS900 should be cut from the correct side when adjusting the length. One of the two ends is flame treated. This flame treated end is inserted into the adjustment screw of the front / rear derailleur and should therefore remain there.
