Jagwire End Caps

These caps are designed for 4mm housing, which is the standard size for most derailleur cables. They are not compatible with 5mm brake housing, so double-check your cable diameter before purchasing.

Brass is significantly more durable and resistant to crushing under tension. While plastic caps can deform or crack over time, these brass caps maintain their shape, ensuring your cable housing stays securely seated for consistent shifting performance.

The open design features a simple, hollow-tube construction that allows the inner cable to pass through freely while the housing rests securely against the cap. It is a straightforward, no-fuss solution that is easy to install during routine maintenance or a full build.

No special tools are required. You simply slide the cap onto the end of your cut housing. Just ensure your housing ends are cut cleanly and squarely to get the best fit and prevent any binding.

The black finish is primarily cosmetic, offering a sleek, stealthy look that blends well with most modern bike frames and components. It also provides a thin layer of protection against corrosion, helping the brass hold up better in wet conditions.
