What will the wear on the Shimano Chain gearbox be like?
As I understand that enclosed chaincase bikes do fairly well with wear. But, perhaps they aren't ridden very far.
If done well, it could be 100% bathed in oil (or a dip rotation). So, one might expect fairly long wear. But, does one have to expect the whole thing to be torn down say every 5000 miles?
Difficult to monitor, so if one doesn't keep up on maintenance, then it tears up the chain, and both cassettes. Perhaps the whole thing just eats itself up?
Or, repairing a broken chain on the road? That could be a nightmare.
Can one limp home on malfunctioning "gearboxes"?
Can it handle those occasional moments when one chooses to shift under a 2,000 W load?
