Fitting new gears or completely overhauling your bike’s gear cables couldn’t be easier, as this Shimano gear cable set has everything you need in one pack. Its stainless steel precision ground round inner cable leaves a smooth surface for low friction while providing high corrosion resistance. The gear outer cable is lubricated internally along its length with low-friction silicone grease to reduce cable friction. A special construction process makes for an axially stiff outer casing that transmits shifting movements accurately and quickly. Plus, the outer casing is lined with a polymer sheath to assist with the smooth operation of the inner gear wire.
