single speed ?

I was wondering if there's a way to run single speed with horizontal dropout's without using a tensioner? Possibly half link?

halflink if the dropouts are shallow, if they are deep enough you shouldn't need anything exta.

look up magic ratio or magic gear in the FGSS forum - there are some gear combo's that work without having to use tensioners or half links.

If you have horizontal drop outs, there should be no issue. If you have vertical drop outs, Use half links, a dremel, or a perfect gear ratio.

With a magic gear you still might burn through chains faster than a "proper" SS. Once the chain stretches there is enough slack to cause it to slip of the chain ring in certain situations. I fixed this on mine by adding a half link. It cuts chain consumption down a bit.

If you have horizontal dropouts then there should be no problem, but if its vertical dropouts whats the problem with using a chain tensioner? I use one on my 29er ss and I love that bike more than anything.

the bike has vertical dropout's. I just busted the hanger of for the first time the other day, so if i'm looking to do away with anything hanging. I was looking around yesterday at tensioner's and the yess tensioner look's nice but i rather do without. All i really ride is skatepark's and some urban.

Are you sure they're totally vertical? Or are they semi-horizontal? Just asking because it took me a while to realize I didn't have vertical dropouts on my fixed gear conversion. They're at a slant instead of track-style.

run a tensioner, get an eno hub, or get a new frame. I personally think the magic gear ratio stuff is stupid.

The perfect gear ratio is fine really. If you can get a gear ratio that is perfectly ridable and fits your exact measurements, why would it be stupid to use it? If you're using it in a ratio that doesn't make sense to be riding or is too high for you, then yes it is not wise to use. They make tensioners somewhere that do not need to go on the derailleur hanger, though.

Plenty that don't hang off the bike. There's a couple that fit on chainstays, there's always the DH route of BB mounted too. Or you could try a ghost cog. not sure how well they work as I've never used one. Also don't know if they're suitable for a mountain bike.

Magic Gear calculator. Works like a charm, as long as you can find the right ring/cog combo for a given gear.
