Keep your bike in tip-top condition. Well maintained cables give you precise shifting and should make your bike as reliable as possible. Stretch and wear over time will reduce their efficiency and effect your shifting performance. Key Features: Fitting new gears or completely overhauling your gear cabling couldn\'t be easier - everything you need in one pack. Die-extruded PTFE coated inner wire leaves a smooth surface for low friction in use, and stainless steel provides smooth shifting and higher corrosion resistance. Outer casing is lubricated internally along its length with low-friction silicone grease to reduce cable friction. Special construction process makes for an axially stiff outer casing that transmits shifting movements accurately and quickly. Outer casing is lined with a polymer sheath to assist with the smooth operation of the inner wire. This kit contains black outer cable. Includes 1.2 mm inner wires (2 x 2000 mm), and black 4 mm outer casing for a complete bike (2 x 600 mm, and 1 x 320 mm), and all end caps
