    Chain Tension for Vertical Dropouts ???

    Hey everyone-

    First of all, yes i know i should have chose a bike with horizontal dropouts but i didnt so i hope you guys can give me some advice

    Currently I have been converting a road bike with vertical dropouts to SS. I am currently attempting to run a 46/16 and I'm having big problems with chain tension. i have two chains that i have been attempting to use, one with a half link, one without.

    with the half link the chain tension is so tight it feels like i am peddling through mud, with out the half link there is a lot of chain movment but it has not popped off.

    My question is how much of a difference will if make if i run a 44/16 (could that be a middle ground between the two chains?)

    thanks a ton!

    It will make a difference, but I would consult your LBS for pointers on this. Showing you how to adjust chain tension is much easier than explaining it (especially on conversions).

    I'd use a surly singleator or a ghost ring. Otherwise it doesn't seem worth the trouble to go singlespeed with horizontal dropouts.

    There's also the ENO hub but that's a couple hundred bucks

    There are hacks you can do like filing down your dropouts, or filing down the axle to give youa few mm's of wiggle room. Also, if you are using a cheap chainring there is a good chance that it is not perfectly round, giving you a difference in chain tension throughout the pedal stroke.

    You are looking for what's called a magic gear. This technique can work but it's a pain in the ass and it won't work anymore as soon as your chain stratches. If your chain doesnt' fall off on the loose setting I'd say leave it. If it does start to fall off I would just run a tensioner; it's the simplest of all your options imo and it will look pretty clean if your ratio is as close as you say it is.

    The only real answer to your original question would've been the eno hub.
