Cheap Shimano one sadly, but given the circumstance, I wouldn't worry too much about maintenance since the weight will definitely be under 30kg (including luggage), the bike itself weight approx 10kg.
Shimano will last for that without any worries though, I would have thought.
As you say, keeping the weight down will help bearings last longer anyway.
