400 miles since the introduction of 1mm rubber

It manely wore in front.  The problem is the front has to be tacked to prevent it from flopping down.  When the material over the tacks wears through, it'll flop down.

The protective flaps wore through.   Nothing to do but glue new flaps on top of the old ones.

The string was indistinguishable from random fibers.  Blog posts since 8/26/18 show the string gradually fraying.  The frayed sections could now no longer be pulled through the holes.  The string was replaced on Aug 26, at least 700 miles ago.  It's amazing it was ever as pristine as it once was.  Not sure what causes the fraying or why it hasn't disintegrated.  

With OSH closed, the smooth Lehigh 1/8" string is no longer sold locally.
