Well, the fact that the top tube and down tube touch where they meet means it likely a small frame. The listing says it's a 54 cm bike but I'd be suspicious of that. I've got a Raleigh Tecnhium that I'm working on building up right now and I just don't think that measurement is right. I'm 5'8" and ride a 52 cm frame, but I've got short legs. If you're normally proportioned you more than likely ride a 56 cm/22 in frame (when looking at road bikes). The problem is, this is not a hard and fast rule when it comes to fitting bikes.

If it truly is a 54, you could make it work, but again I don't think that it is. I have heard that these Technium frames were supposed to have long top tubes so that may be where the seller is getting the measurement from?

Here is a 54 cm Technium frame. It looks bigger than that bike.



If you've got a few months you can probably find what you're looking for on craigslist.

Edit: I see you added your height in the original post. So, given those measurements maybe a 52-54 frame with a longer stem.
