As per title, I'm guessing someone here will have tried this without wanting to file the dropouts of their Cotic or whatever. If so, any joy?
Am considering converting an old road frame (with vertical dropouts) and would prefer not to use a tensioner (for reasons of tartiness only).
Cheers
Try it is probably the answer.
Few calculators on the web where you enter the chaintstay length and it gives you options.
Be aware that a new vs stretched chain means a 1 or 2 T difference on the cog.
Run an SS like this for years - indeed still do.
Yeah, I've found the calculators, just wondered whether it *really* worked as opposed to 'sort of'.
"Run an SS like this for years - indeed still do." is what I'm looking for, thanks 😉
Anyone else?
As an example my marin is tight on new chain at 34X16. After a few weeks chain is loose enough to go 34X17 then about 6 months later too loose again and starts to fall off, so I put a new chain on.
Using SS rings, BMX chain and cogs always worked for me.

Use an 8 speed chain with a half link. Set it up with/without half link to start with so the chain is tight.
When the chain goes slack add/remove the half link as required.
do it. All your single speed buddies will be well jealous. I run a caldera frame with a 32t surly and 16t rear cog. Use a new kmc cool chain with 1 half link from a bmx. Chain stretched after a year but never came off. So just replaced with a new KMC for SSEC and was running sweet and silent!
I want to try the ghost ring - I think that is cool as.
Thanks all...
I've also found this:

I have access to brazing kit... How hard can it be? 😉
Way too much effort 🙂
As above i use a variety of rear cogs (16 and 17t) and the occasional swapping of chains (with or without a half link) to keep my vertical drop out Inbred frame as a singlespeed.
One tip - you don't have to have the rear wheel fully inserted in the dropout for the wheel to stay in place - gives you a little more slack in the system to play around with.
Works well and doesn't involve any bike surgery !
I found a magic ratio with my Soul but unfortunately it only lasted for a little while until the new chain I'd fitted stretched a little. After than I needed an tensioner (until I got sensible and re-fitted the gears!).
It can work but chain stretch is a bit of a pain, as stated.
if you can find the ratio then there's a trick with a file that will let you tension the chain slightly. Don't file the frame but file the axle threads where they pass through the dropouts. File them to a teardrop profile on each side then you can rotate the axle in the dropout and adjust the tension ever-so slightly, enough to take up chain stretch so you don't have to adjust the gearing as the chain stretches.
