I'll admit that I'm a bit obsessive when it comes to mechanics. Bicycles included.
This is about my 2010 Schwinn Madison. I notice that when I slide my rear wheel into the dropouts (or track end) it doesn't sit perfectly centered between the stays (both chain and seat). I can get it centered if I move it about a bit and hold it as I carefully tighten the axle nuts. I measured the frame alignment as per Sheldon's string method, and I get 31mm on the button from the seat tube on each side.
The bike rides just fine. I can ride straight with no hands, and it doesn't show any other symptoms of misalignment other than the wheel not centering in the dropouts without a little tweaking.
Anyone else have this issue? It bugs me a bit, but that's because I'm obsessive and I really appreciate accurate manufacturing.
Well,sometimes thats life.Can't expect precision on the lower end.To get the cantis to work on my '85 Le Tour luxe I had to play with the hub spacing to center the wheel between the seatstays due to one being 2mm longer,leaving the wheel a bit tilted.
To expound, the axle itself may be askew. Happens a lot on the lower end, and don't even get me started on the box-store hubs---they are glaringly obvious. If you're really OCD, you can work up a temporary jig with those laser levels to really key in on the alignment of the frame.
Would check the wheel and components before taking a file to a seemingly solid frame.
