Trim the shift cable to your required length, slip the end cap over the cut end of the wire, and crimp it firmly in place using cable crimping pliers or a similar tool so it grips the strands tightly and sits flush. A well-crimped cap prevents the classic frayed cable-end look and stops the wire from catching on your hand or clothing.

These end caps are sized for shift, or derailleur, cable wire, which is generally thinner than brake cable wire, so while they may fit some brake cables loosely, it's best to use end caps specifically sized for brake cable diameter on brake lines to ensure a secure, rattle-free crimp. Using the correctly sized cap for each cable type gives the neatest, most secure finish.

Beyond looking neat, a properly crimped end cap prevents the cable's individual strands from fraying and unwinding over time, which can otherwise catch on bar tape, cables, or your fingers, and can even make the cable harder to feed through housing during future adjustments. It's a small, inexpensive step that noticeably improves the durability and finish of a cable installation.

Silver and Gold generally blend in with most factory cable and component finishes, while Red and Blue end caps let you add a small pop of colour that coordinates with your bike's frame, wheels, or other accents. Since a bottle contains 300 pieces, most riders and mechanics will have more than enough for many cables and multiple bikes.
