When should you replace bike cables?
Cables should be replaced when they are worn causing the bike functionality to react to that wear and tear. This is every 2,000 to 3,000 miles. Specific damage to the cables or housing is also cause for replacement.
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.
Do shifter cables need housing?
Sizing Housing The less drag on the cables, the better the shifting performance. Housing that is too short will kink and bind, creating even more friction. As a rule of thumb, try to size the housing so it is as short as possible but it still enters the stops and barrel adjusters in a straight approach.
Should I replace shifter cable housing?
Housing most commonly needs replacement when the lubrication in the liner has washed or otherwise worn away, or if contaminants have worked their way inside. Either of these is difficult to see, but will affect the movement of the cable within the housing.
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.
