If topslop1 is all torso/short limbs, he probably has the seat forward to reach the pedals, and doesn't want to ride too bent over, but feels his weight is too forward (seat too far forward.)

The whole idea that a person a certain size needs a certain frame size is akin to saying a person a certain size needs to wear a certain size of pants. Take three guys who are six feet tall, with inseams of 32, 34, and 35 inches, but waists of 34, 39, and 46 inches ... One Size Fits All?

If one size fit all, then when I went from 185 to 265 lbs I didn't have needed to buy a new wardrobe. What a waste of money. How was I to know (not having been a BF member) that all the old clothes still fit---even though I was physically unable to put them on my body?

I'd say, if one follows the Competitive Cyclist measuring scheme very carefully, one can get some useful data. I tired it, and also measured all of my bikes, and found that for me at least, what Competitive Cyclist recommended actually matched what seemed to work for me in the real world. That is why I recommend it. But it takes very accurate measurements using the methods described on the site, and I still cannot guarantee that it working for me was not a complete fluke,.. The system could be total trash, and I just was the one in 7 billion for whom it fit.

topslop1, I heartily recommend ignoring all the "This size Should fit" advice from people who have never met you and question your measurements. Make sure you measure accurately, and see what you get---knowing it is just a guideline.

Get on your bike, set up the saddle so your are Approximately KOPS with a slight bend in your leg at full extension, and go from there.

Everyone has different proportions, different flexibility, and a different preferred riding position. basically, if it doesn't feel right it probably isn't---For You.

When you get it right, three to four hours on the bike shouldn't be an issue (except for people like me with a weak core---I need a five-minute break after about three hours to unkink my back---but it used to be two hours or less---I am getting stronger.) If you don't feel good on the bike right away, and still after an hour ... start looking at where it hurts and what you might want to change.

Probably you can dial in the existing frame with a few parts swaps. if not ....

Sell the bike and buy one a size smaller, that beats riding less and less because it is less and less fun because the fit always reminds you that you got it wrong. Chalk it up to the price of education and after your first couple rides on a bike which really fits you you won't care what it cost.
