I have ridden 2 road bikes and both have a slight left hand inclination it seems. I can see more of the right half of the bike than the left while riding. Is it road grade, roads are built to shed water (seems to be there even on flat roads though). Is it the way I ride? One leg shorter than the other???

2 bikes, one common rider. I would look internally before blaming it on the bikes.

I used to sit kind of crooked on my bike. A teammate pointed it out, and it improved after I started seeing a chiropractor.

It may just be your dominant eye. I can see more of the right half of mine, but if I close my right eye then I see more of the left...

You could be pushing harder with the left leg.

Need a front end alignment

You probably can't rule out the possibility that you're subtly deformed in some way your parents hid from you, but I'm inclined to think it's the slope of the road near the shoulder. I noticed the same thing 20 years or so ago after I realized my tires wore assymetrically--the left side of the centerline wore out faster than the right. when I tried to figure that out, I realized I was seeing more of the right side of the bike than the left. I was sure there was something wrong with me or the bike. Turned out I lived where it rains a lot, and the roads apparently were sloped more than is customary. I solved the tire wear problem by reversing them on the rims whenever I happened to think of it. Either the problem went away when I moved to the desert, or I just quit noticing it. Haven't even thought of it in years. Didn't cause any trouble anyway.

Have you ever been measured?

Sounds like you might be sitting to the right and putting more pressure on that side which would push you left.

to clarify I wasnt saying it was the bikes...but thanks for all the advice. im wondering about sitting crooked or something is off with the fit, as my right knee bothers me too.
