Yes, the dongle dangles...

So far, not an issue. One of the better things about the Birdy is how well it corners, suspension sticking the tires to the road. I have a tendency to take corners fast and lean into them. So far, no derailleur strike in a couple weeks of riding, and was/is not even a worry on my end.

It's a full-suspension folder, but definitely not an offroad bike. I'd be worried if I was riding New England single track with a derailleur hanging low like that, but no issues on the road.

If any derailleur strike ever does happen, I'll just swap it out for a more tucked-away derailleur design, like the Capreo or any of numerous Shimano shadow offerings.
