Serotta click

Not that anyone out there cares, but I have just won an epic battle. At 10:06 PM EST, I fixed the click in the Serotta.

After the following, I finally found the click:
-Removed rear wheel, greased dropouts, reinstalled.
-Removed front wheel, greased dropouts, reinstalled.
-Removed chainrings, greased chainring bolts, reinstalled.
-Removed pedals, greased, reinstalled.
-Removed seatpost, seatpost collar, greased reinstalled.
-Put quick releases from cyclocross bike on.
-Installed road tire on cyclocross wheel, installed, removed.
-Removed cranks, greased spindles, reinstalled.
-Removed front derailleur, greased clamp, reinstalled, readjusted.
-Removed cranks, removed bottom bracket, cleaned, teflon tape, anti-seize, reinstalled.
-Removed stem hardware, greased, greased all stem spacers, reinstalled.

Drum roll please............One of the downtube cable guides was slightly loose. With one turn of a 3mm bolt, this 4 hour marathon could have been over in two seconds. No wonder the sounds seemed to be coming from the drivetrain...no wait...stem...no wait...dropouts...related to torque...not related to torque...related to lean angle....WTF!?!?!? It was coming from the freaking center of the downtube.

Phew.
