Jagwire Sport Derailleur Cable Housing

No, this is specifically designed for derailleur (shifting) systems. Brake housing requires a different coil-wound construction to handle the higher compression forces of braking, so you should not use this for your brakes.

Linear strand construction provides a balance between stiffness and flexibility. It resists compression to keep your gear indexing precise while remaining flexible enough to handle tight bends in your bike's cable routing.

No, the housing comes pre-lubricated with a Slick-Lube liner. Adding extra grease or oil can actually attract dirt and grit, which will increase friction and degrade shifting performance over time.

Yes, 4mm is the industry standard diameter for derailleur housing. It should fit almost all modern road and mountain bike frames, but it is always a good idea to double-check your frame's cable stop size if you are working on a vintage or non-standard bike.

This package includes a 10-meter bulk roll. It is intended for shop use or for riders who maintain multiple bikes and need a long-term supply of housing.
