Singlespeed & Fixed Gear - I gotta funny feelin' about this

As of right now I'm riding a road conversion and it's been a lot of trouble so far. Besides all the crap about constantly having to tighten the back wheel (my chain came off once already when i was about to cross 14th street and my wheel shifted after a hard skid) apparently the frame is a little too big for me as well (58cm/34' inseam). So in my search for a frame I got to check out a gorgeous pogliaghi 57cm frame. Now I don't have much experience riding true track frames (road conversion fix rider) but are they supposed to feel really small? I felt cramped as hell with such a short top tube. I know it has to do with the fact that I'm coming off a bigger frame that I'm already used to but it was still pretty little. Also the pedal/front wheel crossover was really big as well. Is that common? I couldn't really make slow speed turns without running the clips into the wheel at least twice. Besides that though it was super fast, light as air, and fun as hell.

Any suggestions on if I should just get used to those things as well as other framesets I should be looking at? Currently the pogliaghi and a Bernardi are under consideration.

No bites eh?

As you're starting to discover, it's the top tube length that's important, not the frame size. Also, finding stems longer than 130mm is a bear, so that is also a consideration. Both my fix and my road bike have 56cm top tubes with 13 cm stems and 44cm handlebars. They fit me identically, although there's usually a minute whilst I remember that a track bike steers faster than a road bike. Get the length that works for you: with all the long mountain seatposts around, nearly any vetical size you want can be made to fit.

Thanks

Those are some tough questions for someone other than yourself to answer. I don't mind toe overlap, but some people hate it. It is very common on track bikes.
I wouldn't want to ride a bike where I felt 'cramped as hell'. Even amongst track bikes there are different geometries used for different racing events, not to mention custom frames made to personal preferences and body proportions, so it is hard to make generalizations about sizing. In general I guess, track frames have a shorter TT than road bikes, but not always. Do you have a long torso or arms for your height?
If it were me, I would probably pass on the pogi, if for no other reason than I'd rather spend less money on the bike that I use to figure out what I like. Unless you are getting a hella deal, there are quite a few track bike geometry frames- bianchi, khs etc, road bike geometries- iro, surly, etc, and road bike conversions that can be had for less $. I haven't given any of the above mentioned a real ride, so I can't give you any recommendations of where to start, but a lot of people here should be able to give you something. So to end the ramble, I'd get something cheap, ride it for a year or two and really learn what works, fits and what your preferences actually are before buying a dream bike.

It's a pretty good deal for the pogi. 600 including campy headset/BB and some other italian racing cranks. As for road bike geometry I definitely want something with track geometry because of the better responsiveness, I just wasn't sure if the overlap/Top tube feel was normal or not. It shouldn't be that hard to get used to.

The Bernardi frame is only 470 as well which seems like a good deal for a light, stiff lugged frame. Anyone have any experience on them?

track bikes will generally have tighter geometry - steeper angles for quicker steering, and shorter top tubes than a comparably-sized road frame. they also always have a toe overlap issue. the issue disappears when you fully learn how to ride the bike. similar to the issue of hitting your pedal on the ground while turning on one of these. to ride fixed you have to basically learn a new way of riding...but it's worth it. stick with it! at least you'll have an amazing bike to start out with! grab that pogliaghi if you haven't already. that's a steal. if "bernardi" means "DiBernardi", just know they're made with low-end Thron tubing and come with some of the least durable paint jobs on the face of the earth...
