Derailleur cable Shimano Dura Ace Road Shift polymer treatment 2100mm - Y63Z98950

Improve the precision of your gear changes with the Shimano Dura-Ace Y63Z98950 derailleur cable, designed to offer top-level performance on both road and gravel. Derived from the top-of-the-range Dura-Ace and Ultegra groupsets, this cable benefits from a special polymer treatment that drastically reduces friction for smoother, faster and quieter gear changes.

Made from stainless steel with a high-tech polymer coating, it offers excellent durability and increased resistance to corrosion. This treatment also reduces the effort required on the levers, improving comfort on long rides.

With a length of 2100 mm and a standard diameter of 1.2 mm, it is compatible with the majority of Shimano road drivetrains (excluding Campagnolo) and is suitable for both front and rear derailleurs.
