hey, yes, thanks.!
as this forum is completely dead, I had this convo later on crazyguyonabike.com where I got loads of responses which resolved my question in a day.
Yes, the rack probably is bombproof enough for some weekend riding but not expeditions. Knowing that you can't carry much more than 20kg on the rack, it's just plain miserable. The more I look at the bike, the more I understand that it's not an adventure bicycle at all as they claim it.
The only solution as far as I know would be a custom made steel rack but I doubt if the bike is really worth it.
The guy from the above mentioned site checked his Safari and his Tubus Logo- it would fit BUT the rack was a lot higher than the stock rack, and so the lower mount rail for the panniers was actually about the same height as the top of the stock rack. That's not cool. Also the rack was too high for the connectors that are on the seat stay. So...
No one could say though if Tubus CARGO would fit on the bike. Does anyone know on here maybe?
Yes, I've heard about the front also and the best solution would be Tubus Tara which is widely used on Safaris and as far as I know- fits perfectly.
Overall, this bike would be really good for some decent loaded touring in europe but definitely not expeditions in third countries through remote areas which I need a new bike for. Unless, of course, I mount a custom steel rack on it.
