Fixed wheel conversion

Hey Guys,
I have converted my old Trek racer into a single speed a few months ago. I now want to go the extra mile and convert it to a fixed wheel.
The bike has vertical dropouts. Rear spacing is 130mm
At the moment the drive train is simply the 39 chainring driving the 15 on the rear cassette using a 3/32 SRAM chain. So far, chainline and tension seem to be fine. Chain noise is low.
In order to go fixed I clearly need to get a new rear fixed wheel. My little research to date suggests most fixed wheels are built for 120mm spacing.
Any suggestions as to whom I should go to for my wheel build?
What should I be looking for in a hub? Is a fixed/free Flip/Flop a good idea?? Do they come in 130mm?
Small flange or large?
Do I need to change to a 1/8 chain and if so, do I need to get a new Chainring for that size chain?
Are single sprokets available for 3/32 chains?
Thoughts appreciated

You can't suck wheel all day, sometimes you gotta break wind

3/32 isnt a problem, remember that even if you get a 1/8 cog, a 1/8 chain runs fine on 3/32 (that's what i'm running right now - 1/8 chain, 1/8 rear cog & 3/32 chainring). You can get 130 mm spaced rear hubs, check hubjub.co.uk, or sjs cycles. Just google it. Its harder for me finding 110 mm!

Your biggest problem will be the vertical dropouts. remember that on a fixie chain tension is important, as is the chainline. I'd reccomend playing around with as many different cog combinations as you can until you find your magic gear. 39/15 gives you a fairly easy gear, so beware you'll be spinning a fair bit (but on the other hand it makes learning skidding etc easier).

Good luck!

use a half link connecting pin on the chain as well.

I wouldn't trust a magic gear setup for fixed (that's paranoid me) so I'd build the rear wheel around one of these:

i'd say it's not worth the hassle messing with vertical dropouts...

If you want to do this on the cheap, have you considered just building a single speed? That way you wouldn't have to replace the rear hub at all, could use the old derailuer as a chain tensioner (if you can't find a magic gear) and would probably only need to spring for: new chainring bolts (or some washers to space the old ones out) and spacers for the rear cassette (and maybe a cog).

You could then spend some time saving/searching up for a cheap wheel while having a very clear idea of what was needed to make this bike fixed.

Just a thought.

I filed my vertical dropouts to give them some horizontal leeway, worked great.

Although this was on a mountain bike where the dropouts had plenty of meat to work with.

Thanks for that. My bike is set up just as Pip suggested. Have taken off the 53 chain ring and have installed spacers on the rear hub leaving the only the 15 sprocket. Deraileurs already gone.

Reckon I have found the magic gear as I've taken off the deraileur and chain tension is near enough to perfect. Had purchased a half-link prior to setting up the bike just in case but haven't needed to istall it.

Still, will look into the ENO hub.

I really only want a fixed wheel so i can ride backwards and freak out the kiddies.
