Thanks all for the encouragement!
--Bill, congrats on your 200k! I will look for you at the start. I'll be on my green custom.
I think I have/will drop around 3-4 lbs. My philosophy: others are riding pure racing bikes, I can make compromises (for example, -0.5 lbs on saddle) if my body tolerates it.
No kickstand
Aluminum fenders
Front bag with decaleur (no stifferners--big lightener)
Plastic saddle
--Event tires (will try for 400k+ events) Hetre EL--> Ecureuil EL (-0.5 lbs!) (will ride 38 mm vs my preferred 42 mm)
I will send pics and updates as it goes.
