Cable barrel differences.

[Milzy]

I was sorting out what cables I have left and found two MTB brake cables I bought for my retro Marin. I found 10 similar cables but with a slightly small barrel end. They won’t sit in the recess snug like the fatter ones. What on Earth are they supposed to be for?

They must be gear cables.

I've seen similar sized things on old , cheap bikes back when I was at the shop. Had to trim the standards ones back a bit to fit .

Gear cables themselves are a smaller diameter (1.2 or 1.1mm) v a brake cable's 1.5mm. The image shows the two cables you're comparing as the same.

Good info but the one on the right is slightly smaller. The left is more of a traditional barrel shape too.

We had a similar thing at the bike charity where I work. To make them fit properly we ground them down on the grinder. We never throw anything away if we can help it 😉

Problem is they are too slack for MTB recess.

Add some solder around and file/grind to shape/size

My brake barrel diameter is 6mm as well. Most sets seem to be 5mm and no use. Did you find a 6mm set or solder 5mm ones?
