I am in the market for a new road bike and am trying to measure myself for the correct frame size. This will be my first bike ever. Yes, I am a really fresh newbie. There are several sites that go through how to measure inseam length for standover height. Should I measure inseam length with or without shoes on? I do not own cycling shoes yet so will it be ok to wear running shoes to measure? BTW, I am 154.8cm tall with inseam of 69.2cm (no shoes.) Torso length from sternal notch to crotch is 55cm and arm length is 54cm.

It's kind of difficult for me to go and try out several different bikes because there are almost no bike shops where I live that carry anything in my size. The salespeople I've talked to keep steering me towards aluminum bikes which I'm not interested in. I am considering either the litespeed bella or the merlin camena. Anyone out there have any experience or opinions on these bikes?

Thanks in advance for any advice you have.
