Exup cable replacement cheap alternative ?

[b1k3rdude]

well another option I'm guessing would be to use a pushbike cable repair kit, but again I don't know the temp range of the solder used.

I got curious so looked up various temps -

normal solder - 190c
silver solder - 450c
silver brazing - 600c
Brass brazing - 900c
Copper brazing - 1100c

So I wonder what temp the bottom of the headers gets too..?
