i understand this might be a long shot... but
ISO: 808 rear zipp shimano clincher (fairly new)
Have: 404 rear zipp shimano clincher 2009 - excellent condition.
the 808 sold for ~$110 more new i think, so i've got some other stuff i might be able to throw in to make it worth your while...
also have a set of 650c hed 3 tri spokes.
