Shimano Shifting Cable polymer coated The secret is polymer coating that when viewed under a microscope looks like a series of tubes wrapped around the cable. This means less surface area rubbing the internal housing liner and it holds grease longer. Main benefits are significantly less shifting effort and the feeling of a quicker shift action also improved braking power with remarkably less brake lever effort.
OT-SP41 Outer sleeve In the OT-SP41, the outer casing is pre-lubricated with a special silicone lubricant along its entire length for fast, precise shifting. The OT-SP41 reduces friction losses of the inner cable to an absolute minimum so that shifting is fast-responding and effortless. The driver is relieved by the elimination of shifting delays and high effort during shifting, especially in terrain that requires frequent shifting or on the long haul.
