Thanks for the tip -- the DL-1 is always full of surprises. Will check my nuts, stat.

Speaking of those little rod brake nuts: ever notice how the nut on the downtube rod linkage, just below the headtube, is positioned right where, if the front wheel is turned around hard, the fork crown will hit it? It's exactly in the right place to catch the edge of the "thimble" and bend it inward. Genius.
