Hi,

I hope someone can help me with this question. I recently bought a 2001 Lemond Zurich on Craig's list. The bike was advertised as a 53 cm which, by all accounts I saw, should fit me well. However, after a few rides I've decided the bike is too large for me. Now I'm wondering if this is a 53 cm bike after all. The seat tube measures 55.25 to 55.56 cm from center of the bottom bracket to the top of the top tube which makes me think it is a 55 cm frame. Does anyone know where I can get the frame-dimension specifications for the various sizes of 2001 Lemond Zurich frames? I'm probably going to resell this bike and I want to make sure I'm advertising the correct size.

Thanks

Here you go, scroll down to the Reynolds Steel chart.

I've found that people selling bikes very, very commonly list the wrong size. Always ask for measured distance on the frame to compare with geometry charts before buying.

Yeah, you have a 55cm. Same dimensions as my 55cm '00 Zurich.

Thank you liquefied and teterider for your replies. Very helpful. The link to the Lemond geometry charts is particularly interesting. Based on the chart the 53 cm frame has a seat tube length of 54.5 cm, center to center (?). I've measured 54.3. That's pretty close. The top tube length on mine, though, is 56.5 cm - exactly that listed in the chart for a 55 cm frame. Also there is a really big difference in the stand-over height mine measures 803 mm (31-5/8") and the SO listed in the chart for a 53 cm frame is 772 mm (30-3/8"). That's a difference of 1-1/4 inch! What could account for such a huge difference? Do they measure stand-over without tires? It seems there is a mixed bag of measurements and I don't really know what to think. I'm leaning toward agreeing with liquefied and thinking this is closer to a 55 cm frame than a 53.

Thans again for your input and help,

Oops, I got confused in my earlier reply. I read the Top tube length in Lemond geometry chart as seat tube and got confused in my reply. Can I assume that a 53 cm frame should measure 53 cm, or very close to it, in the seat tube length and a 55 should measure 55? Now, based on the perfect match of the top tube lengths, I'm pretty sure I have a 55 cm frame.

Thanks again

I believe the answer would be yes.
Also, check under the bb, my 55cm Bueno Aires has a 55 stamped there.
