Hi chekmx
Will the supplier swap the parts out for you or will you have to make additional purchases?
Might be an idea to buy the stock bike then ride it for a year or so: you'll grow to love, hate or feel indifferent to it. Then can upgrade as you wish. Perhaps it is best to really know the base bike - then you might have more appreciation of the upgrades if you still deem them necessary.
Just an idea! Enjoy and post when you get the bike.
