For the OT-SP41, the entire length of the outer casing is pre-greased with a special silicone grease for fast and precise shifting. OT-SP41 significantly reduces the friction of the inner cable to achieve quick, easy and smooth gear changes. In addition, power loss and fatigue are reduced by delayed shifting when driving, especially in mountainous terrain and long distances. For high-quality versions such as XTR, Dura-Ace, Ultegra and 105, the inner cable is coated with PTFE (Teflon) to minimize friction losses and make shifts fluid.
