Thanks for the email.
Bad news I am afraid.
What you have here is a typical OEM / manufacturers trick to keep the customer buying from dealers.
VERY specialized parts make up the cable, this is definitely not your average brake cable with turned parts.
I’m counting 3 separate mounting brackets, including the very trick integrated one on the end of the outer cable.
To avoid wasting any of your time, I can tell you with certainty that we cannot duplicate this cable.
Just to have the outer cable parts tooled up and made would cost hundreds of pounds.
If you can imagine your cable without it’s mounting brackets, and the integrated mounting/end fitting without its welded on mounting flange, then we are looking at something we could do for you.
