The Shimano PTFE Coated Gear Cable Set is a complete gear cable set designed to suit the top-of-the-range XTR gears. Fitting new gears or completely overhauling your gear cabling couldn’t be easier – everything you need is in one pack. Includes 1.2mm inner wires (1 x 2100 mm, 1 x 1800 mm), black 4mm SP41 outer casing for a complete bike (1 x 3000 mm), sealed outer caps with added tongue for rubber shields plus inner end caps. PTFE coated stainless steel precision ground round inner wire leaves a smooth surface for low friction while providing high corrosion resistance. The outer casing is lubricated internally along its length with silicone grease to reduce cable friction. A special construction process makes for an axially stiff outer casing that transmits shifting movements accurately and quickly. The outer casing is lined with a polymer sheath to assist with the smooth operation of the inner wire.
