Stem Alignment

I have been wondering, what is the proper way to make sure the stem is aligned to the fork and tyre? Is there any special trick, or is it just by eye?

I stand in front of the bike and hold the front wheel betwixt my knees. I find it helpful to set the wheel at roughly 45 degrees from the frame, rather than in line with it. You want to align the handlebars with the fork and the wheel, and if the frame is close to lining up with those, the frame can confuse you.

Close one eye and sight with the other eye directly in the plane of the front wheel.

I alternate from right to left eyes, so one doesn't get tired.

I have the customer sit on the seat. I move the stem back and forth until they are satisfied that it's straight, then I tighten it down. Works every time!

Stand over the top tube and align the bars with the front axle, they're the only two things that have to line-up.

Get laser line level. I got one from the drugstore for $15. It use it to line up my saddle as well. I put it on the seat and it casts a line along the top tube that intersects the center of the headset cap bolt, continues along the stem and along the center of my front tire. Eyeballing cannot be as precise. You can also use it for a lot of other things.

I like the laser idea. I have always just eyed it.
