Shimano Dura-Ace OT-SP41 Housing & Polymer Cable Derailleur Sets

- Polymer-coated, stainless steel inner cable reduces the sliding resistance to achieve lighter and quicker operation and is rust resistant
- OT-SP41 Housing is pre-lubricated with silicone grease
- Sealed end caps to minimize dirt contamination
- Low friction polymer material on the cable may cause slippage at the cable fixing bolt after initial pre-stretch for the cable is performed
