Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

all this on steel frame? did you think this through?

You don't like your Boardman so instead you are going to build a really expensive,
heavy bike with an soft, indirect feeling drivetrain?
You worry about the drag of the dynamo hub but you get an Alifine?
You get a beltdrive and electronic shifiting because you think that will not require maintenance
but then you go with mechanical discs?

Since you are a Princess and the Pea type cyclist I predict you will not even get through
the run in time of the Alfine before you hate it.

This is just a thought experiment- it's not what I'm doing.

I quite like the idea of being a Princess and the Pea type cyclist- does this mean that I have 20 layers of carbon fibre in my saddle, but still feel the bumps?
