The Shimano OT-SP41/OT-RS900 Optislick shift cable and housing set is designed for high-performance shifting. It features an ultra-thin, uniform electrically coated layer on the stainless steel cables to reduce friction. This set ensures light, quick shifting response for both road and mountain bike drivetrains.

The kit includes a specialized OT-RS900 housing segment, essential for the tight bend required by modern "Shadow" style rear derailleurs. Complete with sealed end caps and various specialized outer caps, it provides a fully protected system. This comprehensive package is the factory-standard choice for restoring crisp, reliable gear changes.
