Short inside leg body: smaller frame? I have a bit of a disproportionate body. I am 176cm (5'9") tall, but my inside leg height is only 76cm (2'6"). I want to build a fixed-gear bike and I am looking for a frame of the right size for me. The plan is to use it to commute. All the track frames I could find are either low-pro, or with small backward sloping. And most of them are very compact, which means the top tube is short compared to the seat tube, which really doesn't fit my body. Of course, it is very hard to get a tailored track frame for a good price.

The only solution is then to buy a small frame and use long components (stem, seatpost). Is this a good solution or you can think of something else?
Track frames in general are designed for manouverability, not stability or comfort. This does not make them very good commuter bikes, but if you absolutely need a track frame you know what you are getting into. Extra long stem tones down the twitchiness a bit, but also moves the weight distribution towards front wheel.

Another solution would be buying a road frame with horizontal dropouts and not installing a rear brake. This will get you a top tube that is only moderately short related to your body, but would lose some credibility (if it was 2007, this is 2017 and track bikes are old news anyway).
