Sunlite SIS Cable Housing

This is specifically SIS (Shimano Index System) housing, which is designed for shifting cables. It should not be used for brake systems, as brake housing requires a different construction to handle higher compression forces.

The 5mm outer diameter is a standard size for many shifting systems. Before purchasing, verify that your bike's frame stops and derailleur adjusters are designed to accept 5mm housing, as some modern road bikes use thinner 4mm housing.

Multi-strand construction provides the necessary rigidity to prevent the housing from compressing when you shift gears. This ensures that the cable movement is precise and consistent, leading to cleaner, more reliable gear changes.

Yes, 25 feet is a substantial amount of housing, far more than what is needed for a single bike. It is primarily intended for shop use or for riders who maintain a fleet of bikes and need to replace housing frequently.

You will need a dedicated cable cutter to get a clean, square cut. Using standard wire cutters or pliers will likely crush the housing end, which can cause friction and poor shifting performance.
