brake cables and derailleur cables

[lockpicker1969]

I have an old specialised sirus and I think it is time to renew all the cables . is there a difference between the brake cables and the derailleur cables . I know that the outers are different for the derailleurs but I am hoping that these should be ok .

the cables I have seen that mention any sizes seem to be 1.6mm .

the ends of my brake cable are universal ,will the ends of my gears be the same ?

Brake cables are thicker than gear cables because of the extra stress on them.

If not replacing the gear cable outers, I would squirt some WD40 or similar down them before replacing the cables. Careful of ‘blow back’, though.

And the ripples on the end are different.

Gear cables are thinner than brake cables and both come with either 'barrel' or 'pear' shaped nipples.
