question about chain tensioner
 

I have these dropouts below on my frame but they don't have the hole drilled on them.

I was wondering what kind of tensioner I could use on my frame and if I should even bother to get one because I ride free wheel..

If you have those style dropouts you'll be fine just setting the wheel backwards or forwards until you get the tension you want.

If you still want a tensioner you can always pick up a really cheap hung derailleur and use that.

I think he is refereing to the small screw that goes in the little threaded hole and helps for geared wheel placement. The idea behind them is there is a best place to put your wheel based on the location of your derailer, and your cogset. Since you are running it as a single speed the thing that matters is chain tension, so you do not need the little screws.
