That stem is very long and it's inserted deeply. It's a fillet brazed city bike stem from Belgium. I don't feel threatened by that "sharp angle".

No, spacers don't reinforce the fork steer tube. What a ridiculous thing to say! The extended steer tube does reinforce the stem, though. I'm sorry you don't like the bike. Fortunately, you don't have to ride it.

There is no room for fenders, but I don't need them. It rarely rains here. Some of my bikes have fenders, but they're just for looks. When it does rain, the 39 year old bike stays home. I built it for trips to the farmers market.
