Shimano OT-RS900 outer cable designed specifically for Dura-Ace and compatible rear derailleurs (RD-R9100, RD-R8000, RD-R7000, RD-RX800, RD-RX810, RD-RX812, RD-RX400).
At 240mm, this cable features reduced stiffness compared to standard OT-SP41 casings, allowing it to navigate tight frame curves without compromising derailleur adjustment or shifting performance. Essential for precise gear changes on modern road and gravel setups.
OT-RS900 should be used only on the rear derailleur side. It should not be used on the shift/brake lever side.
