OT-SP41 outer sleeve
The outer sleeve of the OT-SP41 is pre-lubricated along its entire length with a special silicone lubricant to enable fast, precise shifting operations. The OT-SP41 reduces friction losses of the inner cable to an absolute minimum, so that the gearshift responds quickly and is easy to operate. The rider is relieved of shifting delays and high effort when shifting, especially in a terrain that requires frequent shifting or on long distances.
Polymer-coated inner slides
The secret is a polymer coating that looks like tubes wound around the slide under a microscope. This results in a smaller surface area that rubs against the inner casing cladding. Grease is also kept longer. The main advantages are significantly reduced shifting effort and the feeling of faster shifting operations.
