Brake cable sources
 

I'm restoring an old 3 speed and need new brake cables. These particular cables are a specific length with stops on both ends. The brake calipers do not have nut and bolt clamps like normal calipers. Anyplace sell these? Also the cable housings are grooved, I'd like to keep that look. Thanks!

Found some, clarks brand off ebay. Comes with the barrel adjuster attached.

The ones you found are the right size?

I have used a cable knarp for this purpose in the past, but recently I find that if I crimp a brass spoke nipple to a cable, it's pretty much permanent.

They have different lengths. I haven't checked for sizes yet, I look around tomorrow at work.
