|Are Trek's measured center of the bottom bracket to the top of top tube? or to the top of the seat collar?
Also, did they ever make 53cm OCLV frames?

|Center to top.

|The OCLV's actually measure to the top of the seat tube, as it extends above the top tube and is hidden behind the collar. I've never heard of a 53, I think they are all even numbers. I have a 56cm 5500, the c-c measurement is 52cm. The top tube length is 56.1cm.

|A 53cm OCLV does exist but it's under the Lemond brand and the same as a 56cm trek. Built by the same company with different brand names and a different way of measurement.|

|Thanx for the info Chen2. This is what I heard from other people who owned Trek's, but the geometry drawing on the Trek website appears to measure the frame to the top of the toptube. I own a 52cm C-C Pinarello Prince and was trying to find a comparable size on Trek. BTW, I guess Treks are known for longish top tube? My Prince top tube only measures 53.7cm. If I was to go by Trek's top tube sizing I fall somewhere between 52cm and 54cm frames.|
|Depends on how you compare.||Chen2|

|Example, my 56cm OCLV has a 56.1cm top tube, that's pretty much "square". Where the Treks are a bit different is that the top tube is lower on the frame as compared to a classic European frame. And the head tube is a bit shorter which may mean more spacers below the stem, I have 3cm of carbon spacers on my Ouzo Pro fork. I made a comparison between my Trek and my friend's C-40, both are 56cm. Basically similar but my top tube was 1cm lower and his was 1cm shorter. His wheelbase was 1 cm shorter. The seat tube lengths were the same. Of course the angles are different but I didn't try to measure angles. (And yes, the Trek is faster.)
