At last years event I saw no Eroica mafia inspecting bikes. If they did the Le Tour would pass the required equipment regs. No worries here.
I also saw no silent ban on Schwinn or any other brand bike.
On the ride last year I saw a huffy passing a bianchi, much to the bianchi riders chagrin.
To me for this ride
it's the motor more than the machine.
You are supposed to suffer a bit between wine breaks.

I'll save purchasing a colnago arabesque for another time...
My goal is the same as last years goal... to finish.
I'm not worried about weight, or the climbs. They were both challenging but not back breaking.
Some of the descents however, were a bit eye opening.
Brakes and wheels are gonna be a focus on the build too.
Thanks to the folks who gave advice.
