A little history: $6 garage sale 10 speed. I bought it after it had been sitting for quite some time. I've converted it to single speed, for what its worth (nothing lol). New rear wheel w/ suzue basic hub and the front wheel is the original rebuilt with new bearings. I had to buy a new seat post and stem for it.

Why did I have to buy a new stem? Well, the old one, besides being severely corroded, was bent. When looking at the bike from the front center, the handlebars were rotated to the right so that when you were ON the bike, the left side of the handlebars were marginally lower than the right side. It was enough to notice. So, I replaced the stem. I figured somebody wrecked the bike and that was all the damage.

Now I'm not so sure.

The bike rides beautifully in general, except that it has quite a pull to the left. I've examined the bike and I can't find anything obviously bent or anything. I figured maybe the front fork was bent, but I checked it out and the fork legs are straight, and when viewed from the side, neither fork leg is ahead of the other. They seem symetrical.

The only really iffy thing on this old bike is the headset. It squeeks. I know, I know, I need to repack it at the least.

Can anyone offer any suggestions, based on what info I gave? I'd really like to fix this as the frame fits me quite well, really, and I'd hate to have to shop for a new frame.

Thanks in advance, and sorry for the book!
