How big of a gear do you want to push? A 53 X 20 will get you 70 gear inches, but I have no idea if that'll work for your terrain. Personally, I'd use the 39T and fine tune it with a 14, 15, 16, or even 17T cog, depending on how hilly your routes are. Plus, you'll get better chainring clearance, if that matters to you.

Just put this on a road bike and it works fine. The included spacers were needed for a new conversion.

BTW, I paired it with a 42.

I just take apart a couple of cassettes for the spacers and the cogs. Then I just use whichever cog that coupled with the chairing I have to get the gear I want. A lot of times a bicycle shop will give me a couple of worn out cassettes for the spacers in them.
Oh, if it's a Uniglide cassette body, I've found that many times a bottom bracket lockring can be use to hold the spacers and cog in place. To me it looks a lot neater than a small screw on cog does on a single speed.
Cheers

If you have horizontal dropouts, you could probably even use a worn cog that was starting to skip when you were running it with a derailleur.

Took a ride to San rafael's bike kitchen (trips for kids). Found an old shimano cassette with the rivets drilled out and spacers included, acoupla no name cogs. Experiment time!

I use the cheap Dimension splined SS cogs. I got mine over the years from a LBS for $6 each. Plain steel SS cogs for Shimano free hub. I’ve run mostly 42/16 or 42/17 on my 26er. They make them in a lot of sizes. I can’t speak to current availability through part suppliers.
