Hi,

I have strange alignment problem with my old Nishiki road bike. I have done cold setting for the frame to 130 mm spacing. After that I aligned the dropouts.
The rear wheel is true and centered, but when I put it on the bike it sits closer to left side chainstay. Offset is approx. 3 mm. The clearance gets a bit too small with 28 mm tyre.

Strange part is that there is nothing wrong with the frame alignment. I checked it first with the string method and then again with DIY alignment tool.
Both times the result was same: the rear triangle alignment is OK.

I also measured lengths of the chainstays and those were same. There is no visible damage on the frame.

I could move the rim 1.5 mm to right to "fix" the problem, but I would like to hear first if there is anything else I could try.

Edit: The rear axle was to blame after all.
