I like the Phoenix. It'd make a great townie/commuter. Then I looked at the sizing:
Size 60cm bike: 55.5cm seat tube (c-c), 57cm top tube, 14.5cm head tube. What the hell? Where do they get 60cm from any of that? I'd need 2 inches of spacers and a 130mm stem to get the handlebars where I'd want them for a townie.
Does anyone know why they size their bikes so small? It doesn't make any sense. And it's frustrating as hell since I like their frames.

Hmm, my 54cm Phoenix has a 54 TT, so I don't know what to say. That is sort of strange that the 60cm TT is 57 and there's nothing larger.
If you can make it work though, I recommend it. I'm absolutely in love with mine, and plan to do some light FG touring up the St. Lawrence soon. It's like a poor-mans Salsa Casserole, and will gain +999 EXP if this S3X hub ever pokes it's head out of whatever rock it's hiding under.

I know on my mark V the size I got was 59 but it is 56 c-to-c. The seat tube extends about half an inch past the top tube. Their messurement is center to top, not center to center. This is why their sizing seems weird.

They also have higher-than-normal bottom brackets.
it's not really unusual; on larger road frames (ie, larger than a 56) the seat tube is usually longer than the top tube. so a 60cm c-t seat tube will likely have a top tube shorter than 60cm.
