Nope, I meant 2cm. It's indeed pretty hard to ignore if you know it's there, but otherwise it doesn't jump at you. On the worst offenders, if you're careful, watching the rear of the front tire against the top tube as you ride, you can see the front wheel riding a little out of line with the frame. You can also see it by removing both tires, holding a long square section of tubing against both rims (with the help of a friend) so that both wheels are in line, and seeing if the bar is in line with the frame or not. According to the manufacturer I talked to, it's actually quite rare to have perfectly good bikes, and the more badly aligned are found amongst carbon frame bikes because the carbon doesn't always cure evenly or something (I know nothing about it, just repeating what I was told).
