Braided cable? Super-flexy cable?

I wonder if I may call upon the collective knowledge.

I'm building a machine at the moment, that has a very small stem roller. This is key to the build, and I won't be changing it. However, I know from using one of these stems before, it kills front brake cables very quickly.... The only thing that worked really well, was a super-flexible "braided" front brake cable, like the old 2.0mm XT stuff, or what used to come OE on like 1991 Marins.

Does anyone have a source for a braided brake cable?
Super-stickler point is that I want standard 1.6mm, not 2.0mm, as I also want/need to be using the yellow housing I have for this particular project.

All shall become clear in due course!

In summary, 1.6mm braked brake cable, barrel nipple, where can I find some!?

All help appreciated!

Re:

Try superstar components. They have/had lots of cable options in various colours.

Cool Ian, good shout. I've had a look though and can't find a single cable, just cutters...??

I should have some of the 2mm XT if you cannot locate any 1.6.

I had some jagwire braided cable on my training bike until recently, only issue is that it was rubbish. Very stretchy. Made braking a bit hit and miss. Gone back to shimano stuff now. And i can stop again.

This any good: https://www.chainreactioncycles.com/mob ... 19?mx101=n

Cool, thanks Ian, that's the outer, in yellow, that I'm using. I'm after the superflexy inner to avoid it getting frayed by the roller.
Cheers Smithjss70, I may have to give you a shout if I don't have any joy.
Thanks all for helping me out though!

Nick, they dont always have it listed, but it might be worth trying SJS. https://www.sjscycles.co.uk/

Elvedes 7x7 cables are super flexible

I’ve not seen anything else that is as bendy in my many years in the trade

Cheers Mike and Andy. Andy, great recommendations, I shall check it out; and of course Mike, I always forget SJS, but they are a treasure-trove of the hard-to-find
