William, thanks! VERY interesting... kind of a cool feature on Shimao's part. They are indeed old DA hubs from the 90's. 7700 series to be exact. I converted them to 135mm <http://www.flickr.com/photos/cyclotourist/2406321019/> four years ago. I just checked and *both *locknuts are beveled on the rear, but neither of the front ones are.
So, so, so, so... I'm gonna' see if I can find a non-beveled one I may have lying around or swap one out from elsewhere and give that a try! I'll keep looking for the elusive <30 y.o. mechanic. Wish me luck with that one! GREAT advice in this continuing saga!
