I think the correct BCD for Zeus is 120 mm, although I believe one edition of Sutherlands once listed them as 119. I've tried reaming a 118? SR brand (i.e. Japanese, not Super Record) ring, but you also have to file the inside of the ring to make it fit on the spider, and I wound up with so little material between the bolt hole and spider it was scary, and I never actually rode the ring.

One thing you might consider is to buy some 118 rings and "ream them out" with a file or a dremel (www.sjscycles.com). This at least will get you going with NOS items (up those hills ??) until vintage zeus rings show up. In the long run there aren't making either type of ring any more and so you might have to resort to highpath engineering:

I wonder if they will omit all markings ?? Current stronglight 122 bcd rings omit all markings, so that seems almost plausible for the last run of zeus rings ....
