Ok let's just say my fixie conversion was converted a bit cheaply and i stripped the back hub.
Whats the cheapest longest lasting back wheel/hub you guys know of? links would be apreciated

IRO.

$105 for an all silver rear wheel, $110 for all black.

Search if ya wants testimonials.

So, let me see if I understand this:

You bought a cheap rear wheel, and it died on you. And now you want to do it again? What makes you think that you'll get a different result? I believe that's one of the definitions of insanity.

The most important and non-negotiable part of a fix is the rear hub. This is the place where you need to make a good investment, as you've just discovered. Campy (my choice), Suntour, Phil Wood, even Sh*tmano (I can't believe I just said that!) are where you want to look. Yes, even a used Campy hub can run you $100 on eBay easy, however, mine were made in 1975 (yep, that's 30 years ago), and they're doing just fine.

Below that, but still quite good are the IRO, NYCBikes, Nashbar, etc 32 hole flip-flops w/ the sealed bearings. You can probably get a hubset for under a hundred. And they can be had in black, which is cool, and makes your bike go faster. Really.

Next: quality cogs! Campy, Suntour, Phil. Get used to the idea of paying 20-30 bucks for a cog. If you can get one of the above-listed for less, good, but if you want to keep your expensive track hub unstripped, you need to use a decent cog.

You live in NY. In case that means NYC, check out some of the messenger companies: there might be a guy willing to sell you a wheel on the cheap while you save up for proper kit.

And when you get your new wheel, make sure the cog and lockring is tightened down all the way.

actually no i just converted it using the freewheel hub from a bike i got for free.
It was fair for the price
also i bought a $30 surly cog for it at thats time but it didn't fit so i plan on using it for this hub.

what do you mean it didn't fit? it didn't fit the chain? or the hub?

well it fit on the hub, but did not allow enough space for a lockring. it was too wide.

I'd say go with IRO. Get a decent rear wheel from them and you can even buy the matching front wheel later if you'd like.

I agree with most of that, but a few important items were left off.

As far as hubs, Suzue Pro Max are great but still on the expensive side. Still nice but a little less expensive are Surly hubs. You don't NEED campy or phil wood to have a wheel that will last. There are many quality hubs out there. Like was said, look at IRO, or even Formula hubs.

For cogs, Ben's Bikes sells Dura Ace for $20, which is a really nice deal. They also have EAI for, I think, around $30-35. Both very nice cogs.

don't forget about Kogswell too.

there are plenty of decent midrange, sub-$100 hubsets.
just stay away from the Suzue basics, quandos and joytechs.

How are Soma cogs?

I have one.
I don't love it.
Also, I've heard bad things about it.
I'm planning on buying a DA soon.

If you want to go SS on the cheap instead of FG. Get the Gusset singlespeed conversion kit. It comes with two surly quality and two CNC barrels which are mixmatched to help with the chainline.

Not as much options for the perfect chainline though and it is only for converting 8-9speed shimano cassette hubs (i believe) to SS.

Dont do as i did.

Spend money on the rear wheel.

I'll second hyper's negative opinion of the Soma cog. I bought one from Harris (who's local to me). The cog wasn't round. They had no problem exchanging it for a new Surly cog after two weeks of riding. The Surly cog has been fine, though it's got a funky design (which I kind of like).
