How do I tighten my bike gear cable?
Tighten the cable Turn the barrel adjuster on the derailleur clockwise until it is almost fully dialled in. Select the highest gear (smallest sprocket) on the shifter. Pull the cable as tight as possible at the derailleur and attach it to the body via the cable anchor.
When should I replace my gear cable?
Cables need to be replaced on the same schedule as frames – when broken. Housings don’t wear out from the inside, but they do get bent and cracked from either external bumps and snags, or just too much bend when installed. Internal cables don’t wear and certainly don’t stretch after the initial seating.
Are brake and shifter cables the same?
Just like with cables, housing comes in two different types; brake and shifter. From the outside they may look the same – but they are in fact very different. Brake housing is built around a wire that coils down the length of the cable. Shifter cables see different forces so the housing is built differently.
Are bike brake and gear cables the same?
While brake and gear inner cables are nominally similar, the housings are different – brake cables use conventional ‘helical’ housing which consists of a tightly-wrapped helix of steel wire lined on both inside and outside by a plastic coating.
