Those that have flown with folding bikes that have derailleurs - have you run in to any problems with damage? Anything that was easy to repair - like bend a front derailleur back to shape - or harder to fix issues that required replacement parts?

I thought the N360 was 3.5lbs, not 5.5? Either way, yea more weight isn't a good thing, but if that means a lot lower chance of something breaking then it would be a viable option.
