Looks very dicey on this 52cm bike Zeus so it is no wonder your smaller bike has a problem. Note barrel all the way up.
I think you'll need every trick in the book. Thick shoes, minimum straddle wire, minimum yoke width, shortest possible hanger. The ultimate somewhat dirty trick: drill a hole crosswise through the seat post and eliminate the hanger, just running the cable through the post (be sure and profile the exit hole). Extreme problems require extreme measures.

> I am working on an old Zeus bike. It seems all original. It is
\r?\n> the durifort tubing model with all the standard Zeus compoents
\r?\n> from the late 60's or early 70's. It is a small frame, about 49cm
\r?\n> I am having lots of trouble with this bike. The latest is with
\r?\n> the rear center pull. It is the Zeus alpha. It had what seems
\r?\n> like the original cable stop on the seat bolt, with the sliding
\r?\n> barrel quick release to remove the wheel. The straddle cable
\r?\n> seems orignal and the right length - short. But even so, the
\r?\n> small cable fitting that can not be set high enough without
\r?\n> hitting the brake cable stop. I have new pads, and the original
\r?\n> Zeus 700c sew up rims.
\r?\n> I tried a Mafac cable stop without the release mechanism, and
\r?\n> that is no better. Could Zeus have sold a bike that did not work
\r?\n> out of the box? Something seems odd. A larger frame would not
\r?\n> have this issue.
\r?\n> Let me know if you can think of anything, or have some nice side
\r?\n> pull Zeus brakes for me:)
