Built my dream gravel bike fully loaded:
Full Carbon
Dura Ace Di2 shifters, brakes
XTR rear Derailleur
New Clx 32 650B wheels
Fizik Aliante saddle
WTB tires
GRX Crankset, not the Dura Ace
It cost me an arm and a leg to built this bike. Parts now are at a premium as you are already aware of.
In a situation where I will have to sell my dream gravel bike. My loss is your gain
