Kitted up last night, clipped in, set off, felt a weird clunk. headset was loose. Went inside to tighten and found the expansion plug had slipped. Went to re-seat the plug and the expansion nut came unthreaded and fell into the fork. I unkitted, then spent the rest of the evening glueing the "AirPlug" that the TCR came with and cleaning my old bike up for selloff. Man, I sure am collecting red boxes on TP
