Keep your bike in tip-top condition. Well maintained cables give you reliable braking and good modulation of your stopping power. Stretch and wear over time will reduce their efficiency and effect your braking performance. Key Features: Complete top-of-the-range brake cable set designed to suit Shimano Dura-Ace and Ultegra Road bike brakesets. 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 lined with a polymer sheath to assist with the smooth operation of the inner wire. All you need to overhaul your Shimano brake cable system. This kit contains black outer cable. Includes 1.6 mm PTFE inner wires (1 x 1000 mm and 1 x 2050 mm), and 5 mm outer casing for a complete bike (1 x 800 mm and 1 x 1400 mm), and all end caps.
