I threw a Vandero 2 guard on my front wheel a few days ago, and it's been spinning like shit ever since. It used to be that I could give my wheel a good spin with my hand and it'd keep going for a few minutes. Now it'll go around a few times and come to a stop. I'm fairly sure that the wheel bolts are a bit bent, so that could be it, because it spins just fine when the wheel is loose.
I don't really notice it too much when i'm riding, but i'm assuming the rolling resistance is still there. Anybody have any other ideas why this is happening, or how to fix it?
