|This and many other web sites have sizing info. Pay particular attention to the inseam measuring technique. Inseam is not your pants length. 34 inches would be pretty short legs for someone 6'-3" tall. As an example, I'm 5'-7" with a 32-5/8" inch inseam. If your legs are really that short, you will have a tough time finding a bike with enough top tube length, that isn't too tall to standover. Standover clearance will have to be kept to the minimum 2cm (3/4").
The most common formula for large frame sizes is 28cm (11 inches) less than inseam. Check your inseam and post again with accurate info.

|I know and trust the shop where I ought it A LOT (Mtn. Pedaler in Eaqle, CO). He measured my inseam, arms, and torso. I'm a little over 6 feet tall but have pretty short legs (30") and a long torso and ape like arms. I ended up buying an IF Crown Jewel because of the longish top tube. I went from an older Cannondale 2.4 that was short, length wise, to a more streched out bike. It took a week or so to get used to it but I like it a lot now. These are some things that I was not really aware of but upper body and arms should be taken into consideration also.|

|I have a 34.25 inseam and I should be riding a 59 but I'm on a 61. The standover is OK but the tt lenght is a tad too long. That's the important measurement..|

|I am 6'3 with a 34 inseam and I have riden a 57 Lemond, a 59 Merckx and a 60 trek... and all were fit to me.
It is not about the standover!!! It is the length of the toptube!!!
go to a shop that will put you on a fit bike.

|The frames mentioned are all measured differently. Center to top, center to center and center to top of seat tube respectively.
While top tube length is important, it's no more important than getting a good vertical fit, IMO. I would rather ride a frame that was off by 1cm horizontally, than vertically. Changing the stem length by 1cm is preferable to an extra 1cm of steering tube spacer to make up for a too-short head tube (from a too-small frame).
You also can't directly compare the top tube length of frames with different seat tube angles. Once you compensate for differences in seat tube angles, most frames don't vary by more than 1cm in the same frame size. It's only the folks who require an extremely long or short stem who might find this difference to be critical. I've checked the geometry of a large number of 55cm frames (my size) and rarely find one that would require an adjustment of more than 1cm from my normal 110mm stem.
