Thank you all for the well-thought-out responses to my Raleigh chain line problem.

I performed the taught string test, just as “number 6” suggested. And guess what? The results strongly pointed to misaligned chain stays. So, then I followed Sheldon Brown’s procedure for bending the stays into alignment. I now get good string measurements and the chain no longer rubs on the large front sprocket.

According to number 6, many Raleigh chain stays were out of alignment, presumably from the factory. So, I’m curious, what gives here?

Thanks again,

Jason
