Sunlite S.I.S. Housing

No, this is specifically S.I.S. shifting housing. It is designed for gear indexing and should not be used for brake systems, which require a different, compressionless housing construction to handle higher stopping forces.

The 5mm outer diameter is a standard size for many older or specific shifting systems. However, modern road bikes often use 4mm housing for derailleurs, so you should measure your existing housing or check your frame's cable stops before purchasing to ensure a proper fit.

No, this is a bulk roll of housing only. You will need to purchase inner shifting cables and the appropriate ferrules separately to complete your installation.

Bulk housing is significantly more cost-effective if you maintain multiple bikes or perform frequent maintenance. It allows you to cut custom lengths for specific cable runs, ensuring a cleaner fit without the waste of pre-packaged kits.

For the best results, use a dedicated cable cutter designed for housing. After cutting, always use an awl or a small pick to open up the inner liner, as the cutting process can slightly crimp the end and cause friction.
