Sizing a Giant Propel Advanced 1
Hey this is my first time on a forum of any kind so I apologize if I am posting incorrectly or in the wrong section. I’m looking at picking up a 2014 Propel Advanced 1 M/L size. I am 6’1”. I think a large would be my option on most other makes/models but after looking at the top tube length (57.5”) on the is model/size it seems like it would fit fine. I have also read people tend to size down on this model due to the longer thanks average top tube length.
currently riding a very old mercier Aquila 58cm that has a top tube length of about 57.5cm also.
So my question is with a M/L fit me okay? Main concern would be if the seat height race can handle me. 34” inseam. Giant doesn’t have many dimension measurements on their frames.

Welcome to BF's.
In general, I think people with longer legs and a shorter body might be more comfortable on the smaller frame size if your in between. I don't know about this specific bike though. You just need to check the seat max height. Its probably OK though. You might need a longer seat post. I highly advise trying one out first.
In my case I have short legs for my height and am in between small and medium frame size. A medium would be best except the standover height is too high on a medium. So I went with the small frame. By moving my seat back on the rails I have found a position that works for me.
Some bike geometry is more forgiving then others no doubt. I'm guessing with a full fledged race bike proper fitting is more important. As we get towards endurance and hybrid bikes we have more room to fine tune a slightly undersize or oversize frame with seat and handlebar adjustments to work well.

What does the Giant sizing guide say for you on their website? If you are in the overlap then either will do. Until you are actually on the bike riding it you just won't know. That is why test rides for as long as the bike shop will let you is really helpful.
No amount of formulas and calculation will put you in the perfect bike any more than what the bikes manufacturer came up with. To do better requires some of your own personal experience with bikes of that type.
Don't make the mistake of trying to compare bikes of different geometries and tube lengths to a new purchase. And unless you plan to do a lot of mileage per week, say in excess of 150 miles per week, it's not going to be a big deal if the frame is two sizes one way or the other.
