Yes sir. About typical set of issues. But the top end... dang.
How's that slime in the tires feel? I've heard here that you can feel it rotating as you ride.
I prefer some thorn proof tubes and a thick (cut inner tube) liner, but I don't always do it.
400 miles is a bit. When it comes time to service the bearings on that thing, everyone has an opinion, but I use marine bearing grease. It's cheap, and works great.
Sounds like you have a pretty good grip on it. Ride safe, stop well.
