Jagwire Shift Housing Connectors

These connectors are designed to join two separate sections of shift housing together. They are particularly useful when you need to extend a housing run or connect segments to achieve a custom length that standard pre-cut housing cannot accommodate.

No, these are specifically engineered for shift housing. Brake housing typically has a larger diameter and a different internal construction, so these connectors will not provide a safe or functional fit for brake systems.

You need to match the connector size to the outer diameter of your existing shift housing. Most modern derailleur systems use 4mm housing, but some older or specific internal routing systems may use 4.5mm, so it is best to measure your current housing with calipers before purchasing.

When installed correctly, they maintain the integrity of the housing run, ensuring the internal Slick-Lube liner remains aligned. This allows the cable to pass through smoothly without adding friction or causing the compression issues that lead to sloppy shifting.

While they can technically join two pieces, it is generally better to replace a kinked section of housing entirely. A kink often indicates internal damage to the liner or the housing structure, which can compromise shifting precision even if you bridge the gap with a connector.
