why not just buy a trek 520 and have a workhorse bike perfectly suited for centuries, club rides, commuting, and sag tours? Maybe your idea of bikes is somewhat more esoteric, and looking for bikes built with expensonium/scandium/unobtanium to please the crowd, but why not please yourself first, with a solid, reliable, steel touring bike?
