The best mechanical shifters and derailleurs can't work to their engineered specifications without a high quality cable gliding smoothly within cable housing. Shimano's Optislik 1.2mm derailleur cable starts with a high quality, multi-strand, wound stainless steel cable, which is given an minimalist electrically-applied coated layer, which improves the ergonomics and reduces the shifting forces by 20% through its hyperslick properties. Durable and smooth throughout normal cable life, affordable Optislik cables allow your components to work effortlessly, with the excellent performance you desire.

This 2100mm long individually-packaged cable is packaged with a single derailleur cable end cap, and features a fully integrated Shimano-type barrel stop. It works with all current generation, and most past generation Shimano shifters and the generous length is appropriate for virtually all non-tandem bicycles.Now when you can change your inner cable wires out, you can not only refresh your drivetrain, but improve it, with Optislik cables.
