SHIMANO OT-SP41 Polymer Coated Shifter Cable and Housing Set For Rear Derailleur Only Black – Y01V98112
The secret behind the polymer coating is noticeable under the microscope.
It looks as if many small rings are wrapped around the cable.
These minimize the surface area that comes into contact with the liner and grease lasts longer.
The main advantage is the reduction in power required to shift and the feeling that shifts are faster.
Braking power is also increased while decreasing the amount of power that needs to be applied to the lever.
Original Shimano parts guarantee that all components work perfectly for optimum performance and maximum safety and longevity.
