I have a Windsor Timeline, and I was given a freehub rear wheel that I converted to single speed so I can have a quick way to change from the 700x32 that come with the bike, to a 700x25 depending on my ride that day. The wheel set that I converted is a quick release, and I am worried about it slipping when I am cranking up a bridge (Florida Mountains). I took it for a quick test drive around the neighborhood and had it slip a few times on me.

Do I need to just crank down on it super hard, or can I just put a bmx chain tensioner on it? The thing that worries me about the chain tensioner is the fact that the only part sticking out past the drop outs is the skinny little skewer, which worries me putting much force on that.
