I'm so lost in sizing!(9 posts)

I'm so lost in sizing!Racer C

I offer a desperate plea to anyone who can help. I been through hell trying to find the correct size frame for myself. I've heard such conflicting things but right now I'll take any advice I can get. I'm looking at LeMond ti and OCLV bikes because I can get a great deal on them but I don't know about the sizing. I'm 5'9 and have a 32.5 inseam. Please help. Thank you

but according to wrench science, my c-t measurement is 55 and trek's are sized from the center of the bottom bracket to a few centimeters below the seat collar...at least this is what the website shows. why would I take a 56 and not a 54?

I'm 5'10" with a 32/32.5" inseam - I test rode both a 54 and 56cm OCLV - I found the 56 to be too long in the top tube and did not have any problems with KOP on the 54. If I had liked the bike I would have gone with the 54. If they made a 55cm it probably would have been closer.
Yep, used to have one.djg

The 56 measured very close to 54 cm on the familiar c-top criteria. Of course the top tube was a 56.

What the web site shows is wrong. I have a 56cm 5500 OCLV. It measures 56 to the top of the seat tube, more than 1cm above the top tube. I'm the same size you are. Take a look at the drop from the top of saddle to handle bar. Make sure you are going to be comfortable with it. The top tube and head tube are about 1 cm lower than most comparable bikes. I'd sure recommend a test ride.

OCLV size 56 has a seat tube that is exactly 52 cm center to center with a 56 cm top tube center to center. I just measured it as we speak.

I ended up buying based on the TT & have a 2.5 inch drop to the bars with 2.5cm of spacers. It doesn't look great but it fits.

If you decide to size based on the seat tube, make sure that they swap out the stem for your test rides so you are sure that you can get comfortable & that the handling is what you want.

Unfortunatly, if you are not short legged/long torsoed, the only way you won't have a significant drop to the bars is with spacers.

I'm 5 8.5" with 31" inseam and own a 54 trek5200
With the seat all the way back I can just get my knee over the center of the spindle at 3 o' clock. I don't think you'd be able too -- your knee would be too far forward. This is the stock seat -- maybe other seat rails allow more backward movement. My arm length is right on. So I'd recommend 56cm trek measurement if you're shopping that line -- as long as you're not reaching too far foward to get to the grips, and then you'd have to change to a shorter stem maybe. I'm not an expert at fitting but I hope this helps.
