Singlespeed & Fixed Gear - track hub for fixed MTB use

I'm going to build up a fixed wheel for my Redline monocog, and my two best options are to use a respaced track hub or a bolt a modified cog onto a disk hub.
I was just curious if anyone here specifically has experience with using a trackhub for fixed gear MTB. Will the threads of the hub/cog/lockring easily strip out (even if properly installed) because of the lower gearing, or is this not really a concern.

While I don't know much, I do know that Level hubs rock. 120 or 135, bolt on cogs with torx bolts, really strong axles. A bit heavy, but so what?

don't know if stripping is a concern, but chainline is, in terms of hub(chainline)/frame compatabililty. a track hub's 42mm chainline means that a chainring @ 42mm may hit the chainstays. hence the standard ss mtb 52mm chainline.

A friend of mine has the OnOne Double Fixed Hub. It is spaced 135 mm. He rides hard and is quite satisfied with it. Plus you can run a freewheel on one side for longer downhills.

But I also know of people, who rock the Miche Primato Pista rear hub offroad with no problems at all (Respaced of course).

The Primato Pista can be respaced assymmetrically, so the chainline fits Mtb-cranks.

My monocog has 110 mm spacing, so that may not really be a problem there.

I think you could do that with any fixed-gear track hub, but on a MTB, you might end up with some funky dishing in order to get your chainline right.

Also, since it's a redline, it might have messed up spacing anyways... they only went to 135mm rear spacing this last year. 2005's and before had 110mm spacing, in which case a 120mm hub would work if you bend the stays a little (only do that if it is steel).

in that case, you want a keirin hub, which will not be sealed. You could fix a BMX cassette hub with JBweld?

Actually, this is not the case (at least, as far as I know, my Miche wheelset is spaced for a 120 mm rear end, but I have seen it done).
The Primato Pista, in the normal track configuration, requires an assymmetrical dishing. If you respace it, the dishing will be closer to a symmetrical dishing.

Actually, there are a couple of BMX disk hubs, which would do the job perfectly...but the ones I know of are absurdly expensive.

in that case, why not just spin a cog on there and keep your rear brake on the bike?

de-space virtually any 120mm hub down to 110.

the kogswell hub is based on a MTB hub, so that's worth a try. But those guant locknuts might make de-spacing a bit difficult.

just respace a front disc mtb hub (cheap!) from 100 to 110, then bolt on a cog.

keep the front brake if you go off road.

whoa whoa whoa!!

since when does a monocog have 110 rear spacing? every one I've ever encountered has had 135 mm rear spacing, which would require the appropriate size.

fixed gear mountain biking is a lot of fun, but be very mindful of your descents. Hell of easy to go over the bars when you can't coast. also, I would say to go with 170's for cranks. you don't want to cliip a pedal on a rock or something.

^ monocogs were all 110mm up until 2005 i believe.

if you have the $. phil wood has exactly what you are looking for.

i did this with my monocog and put in a promax hub. the chainline isn't perfect, but it's rideable.

I would just remove the big locknuts from any sealed 120mm hub, and replace them with smaller ones.

2006, actually. They were still 110mm until this year.
