[Closed] warning roady content size problem

I got my first road bike after 25 years of mtb,s ...mail order i live in France and its not easy to buy a drop bar tourer here.

Its a revolution country traveler siz 55 cm Iam abot 5'10 but not very flexble due to breaking my back in a mtb accident 10 years ago...

Any way the bike has a very long top tube messurment about 30 mm more than normal so i am now told. it comes with a short stem 75mm to counter this but that makes it very hard to adjust i tried a 60mm but it gets twitchy as hell.

It allways feels like i have to much weight forward , is there any thing else i can?

If not would all the parts swap over on to a planet x london road or Kaffenback . I know wheels wont go but i can source locally at a good price.
