stuck between sizes.Drew

I'm just recently getting back into road bikes. I plan on getting the KHS Flite 300. My daughter just got one two days ago and I think for an entry level bike it's a nice setup. My question is this. I tried a 56cm and I was able to lift it about 3 inches, maybe 4, while I straddled the top bar. The seat tube length on the 56cm is 22.0" (c-c), standover is 31". Would I be better off with a 58cm with a seat tube length of 22.9" (c-c), standover 31.7"? Thanks in advance!

Although stand-over is a good size guide, you should never use it as your only size guide. For example, some bikes have slopping top tubes, so the stand over height is reduced, but the overall fit of the bike is the same. I personally have a long body and short legs, and bikes that I am comfy on for any extended period are ones that I can barely stand-over. On road bikes Body fit is just as important as leg fit.

The bst way is either to get your local bike shop (LBS) to fit you or just take the bike for a ride and see which size is a better fit.

All just my opinion of course...
Depends a little on what you'll do, tooCory

I tend toward the larger frame, maybe because I'm 6'4" and often have to settle for stuff that's too small. I'd trust the bike shop to fit you IF they have both sizes in stock. But I can't count the number of people who've tried to sell me a 62cm or even 60cm frame because that's what they have, when I really need a 64 or 65 they don't stock.
The reach can be adjusted a little by changing stems. If you'll be riding mainly in places where you can stay in the saddle, and don't need to be putting a foot down all the time, the larger frame might be more comfortable. In traffic or anyplace else where you'll be stopping often, you might appreciate the extra clearance of the smaller one. It's a compromise either way; try to find the one that discommodes you less.
3-4 inches is way too much...dave

One to two inches is enough standover clearance (in bare feet), for a frame with a horizontal top tube. If you get the 56cm frame, you will have too much seat post exposed, and too much vertical distance from the saddle to the bars, which won't be comfortable. You may even need a 60cm from your description.

I'm very particular about vertical size, when using threadless stems (which have limited vertical adjustment). I keep the standover clearance to 1.5 inches or less.

Horizontal fit shouldn't be ignored either. As the frame size gets larger, so does the top tube length. It's easy to change the stem length 1cm, to make the reach equal to the next smaller, or larger frame.

You just need to size your frame. These sites can help:

Thanks for the above links. Unfortunately the half of them place me on a 54cm, the other on a 56cm. The 54 is definitely out. I am leaning towards the 58.

Have you looked at any other brands? There's an awful lot of bike MFG's out there. If you post your budget and some other info (i.e. riding style, what you are looking for in a bike etc....) you'll probably get a bunch of suggestions. The more info you give, the more info you'll get back. No matter what you do though, just about everyone on this board will tell you not to compromise fit for anything.

I have also been looking at the Fugi Finest but for $650, thats $125 more then the KHS Flite 300. Looking at the specs side by side I don't see that much difference other then name. Anyone have any thoughts on either the KHS or the Fuji?
