Jagwire's Open End Caps for Shift Housing are quality ferrules that put the finishing touch on your shift cable housing sections. They reinforce them so they stay straight and allow the cables and derailleurs to operate as smoothly as possible.
Open end caps deliver low friction performance and are less expensive, but do little to protect the system from contaminates. Great for use on bikes with uncoated cables in areas with a lower chance of contamination from water or dirt, they are available in multiple sizes, materials and colors. Use open end caps when little protection from dirt is needed, in areas such as levers.
