Jagwire Derailleur Cable Housing

No, this is specifically designed for derailleur (shifting) systems. Brake housing uses a coiled steel construction to handle high compression forces, whereas this linear strand housing is optimized for the precise, low-compression needs of shifting.

Linear strand construction runs the steel wires straight along the length of the housing rather than coiling them. This provides the stiffness required for crisp, accurate gear indexing while remaining flexible enough to route cleanly through tight bends on your frame.

No, the internal Slick-Lube liner is pre-lubricated during manufacturing. Adding extra grease or oil can actually attract dirt and debris, which may increase friction over time.

While 5mm is a standard diameter for many derailleur housing setups, you should verify your specific frame or component requirements. Some modern road bikes or integrated systems may require 4mm housing for tighter routing or specific cable stops.

To get a clean cut, use a dedicated cable housing cutter rather than standard wire cutters. A sharp, specialized tool ensures the internal liner doesn't collapse and the steel strands remain flush, which is critical for smooth shifting performance.
