Risk of spreading rear dropouts
 
Will my Reynolds 531 frame withstand spreading the rear dropouts from 110mm to 120mm without a great risk of dimpling the stays?

Thank you.

track bike?

Really depends on the condition of the stays, but I have never had a problem. I just spread a 531 frame from 120 to 130 without issue. That bike had round oval round stays though. 531 is very ductile. Some of the newer heat treated steels have more problems with this

Yes, the frame is a 1951 R. O. Harrison Track. The stays look pretty hefty to me, not pencil thin. Thanks for your input.
