Sandra, I have the Giant OCR A1W In the gold-black-silver.

Hotawmighty, it's a beautiful machine.

Mine is frame sized XS. I'm 5'2" with really short legs.

I upgraded from a Trek 1000WSD.

Besides the structural/mechanical upgrade, I really did it for two reasons that are probably not applicable for you:

1. I wanted a bike w/ 700c wheels. The Trek's were 650c. I felt like I might be able to keep up better on club/group rides with bigger wheels. So far, I'm still as slow as molasses. But the frame geometry of the Giant XS allowed for 700c wheels where the 48cm Trek had 650c wheels. I don't quite have the standover room on the Giant that I should have. But then I'm a very short woman of very wide proportions and I probably looked like a circus clown riding a teeny-weeny bike on that Trek.

2. Color. Sounds petty, but I did not want a pastel colored bicycle. Most of the bikes I was looking at that might fit me were in colors that made me want to vomit. And I wanted a bike in a primary color that was not the color of my old bike and didn't match the color of anybody in my club. That gold/black/silver OCR A1W is one pretty bicycle. Unfortunately, that bike's beautiful color scheme clashes with all of my cycling clothes, gloves, helmet....I have an orange helmet, spring green gloves.......and some goshawful jersies. Nothing looks good with it.

Anyway, the Giant OCR A1W is a fine bicycle, and she's a looker.

Other things: gear shifting is smoother. The Giant is a double and my Trek was a triple. It's easier for me to keep up with the gears since I'm mechanicially challenged. I find myself pedaling better, cross-chaining less. Just generally riding in a more suitable gear more often.

Just from a human standpoint, don't settle for one bike because if you have your heart set on another, you may not be satisfied.
