Jagwire Sport 4mm Derailleur Housing Info
Jagwire Sport 4mm Derailleur Housing is a straightforward, reliable choice for mechanical shifting systems that need consistent performance without excess weight. Built with a compressionless construction, it's designed to deliver crisp, accurate shifts by minimizing cable movement loss through the housing wall — a detail that matters most under load or on longer cable runs.
The 4mm diameter keeps things compact and compatible with most standard derailleur setups, and the black finish works cleanly on a wide range of builds. Whether you're replacing worn housing on a commuter or refreshing the drivetrain on a road or gravel bike, Jagwire Sport housing gives you a dependable foundation to work from.
