Hey Nicolas
Having a Sponsor is always a good option

So let's have short look on the W4

Frame o.k.
fork o.k.
gruppo Shimano
- Cranks, Shifter, Rear and front Derailleur - Deore will do it
- bottom bracket - the best you can get (you don't want to change it somewhere in Africa!)
- wheel set: as well the best you can get: good hubs (LX or XT, Dt Swiss Hügi Onyx or compareable) DT Swiss Spokes Competition 2.0-1.8 and a durable rim (maybe sun rhino light)
It' very important that the whells are made as good as possible, don't "save" money here! A fine address in Germany is www.whizz-wheels.de, but of course there are more options
- Breaks: The HS 33 from Magura has more Power and an excellent reputation, a real premium "fix and forget" break. The HS 11 is the smaller brother
-stem: I prefer fixed stems, just check out your perfect position and forget about the variable stems.
- Saddle Brooks: what else
- light: I prefer the SON Hub Dynamo (Expensive!!)

So that's it for the moment, the Fort frame will do the job, and everything else can be replaced if necessary.


P.S. You might ask Rohloff directly for sponsorship. They support a lot of world travellers. Just give it a try!
Cheers
