Shimano Dura-ace OT-RS900 / OT-SP41 Gear Cable Kit

Shimano Dura Ace Polymer Shift Cable Set OT-RS900/OT-SP41
The new DURA-ACE RD-R9100 must be assembled on the bicycle with a special outer casing, OT-RS900.
The secret in polymer coating is that when viewed under a microscope it 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 improves braking power with remarkably less brake lever effort.
Purpose of OT-RS900
The radius (r) of the curved cable that is routed from the bicycle frame to the RD-R9100 become smaller compared to the radius generated with other rear derailleurs, as indicated in the images below. The commonly used outer casing, OT-SP41, is too stiff for such small radius that it could cause technical problems on the adjutment barrel and disturb quick and smooth engagement and disengagement of the rear wheel from the frame. By using the OT-RS900, such problems can be avoided as the stiffness is reduced on OT-RS900.
