I know some pals would frown on this and I have mentioned this before. I get my lifetime supply of cables
from here.
It costs me less than $4 for a complete set (enough for a full build) and I have used them on all my bikes. They worked fine and at that price, I can overhaul or rebuild as many times as I like. Obviously, if you gonna compare it to Jagwire or the other brand names, this option won't be viable for you.
