Jagwire Sport Derailleur Cable Housing

Yes, this 4mm housing is designed for standard derailleur systems on both road and mountain bikes. It is specifically engineered for shifting cables, not brake cables, so ensure you are using it for your drivetrain only.

Linear strand construction prevents the housing from compressing under tension. This stiffness ensures that your shifter input translates directly to the derailleur movement, resulting in crisper, more precise gear changes.

No, you do not need to add extra lubricant. This housing comes pre-installed with a Slick-Lube liner that provides continuous, low-friction movement for the life of the cable.

No, you should not use this for brakes. Brake housing requires a coiled construction to handle high-pressure stopping forces, whereas this linear strand housing is designed exclusively for the lower-tension requirements of shifting.

To get a clean cut, use a dedicated cable cutter rather than standard wire cutters or pliers. A sharp, high-quality cable cutter will slice through the housing and the liner simultaneously without collapsing the structure, ensuring smooth cable movement.
