Bike is ready to go

Trek Domane 4.3

I replaced the saddle with a more comfortable one.  WTB Speed Comp Saddle

I changed to tougher (but so much more heavy) tires and tubes.
Forté Road Puncture Resistant Presta Tube 700c x 23-26

Continental Gator Hardshell Road Tire

I added a headlight and taillight.

No way I'm going to weigh my bike now.  I can't wait to get home and remove all this stuff!
