Freebird, Graham, tanks for all the suggestions.
Graham I read the articles you posted, very interesting. I think that I have the final cockpit setup, again is not only height I need my elbows closer to my body.
1) I will use a stem riser instead of an adjustable stem.
2) I will use a very short stem or BMX stem, probably no more the 50mm.
3) I will use the Jons H-bar bend or a similar handlebar. For example I saw the Soma Sparrow.
If it doesn't work I will try another setup. It will cost me money but for now I think that's it.
