Jagwire 4mm Sealed End Caps (Bottle 100) Black

Jagwire's sealed end caps are an excellent choice for shift systems when you're looking to balance low friction performance with protection against contaminants. A lower friction option than a hooded end cap, sealed end caps have an internal rubber o-ring to help keep the housing clean and dry. Install sealed end caps when you want protection from dirt and debris, but also want to keep friction to a minimum in areas like frame stops.
