I have a 1988 Miyata 615 touring bike. I'd like to update the bike with modern 135mm touring wheels.
The Miyata has longer 445mm chainstays and is a heavier touring frame, by 1988 standards.
There are a couple of professional frame builders in my area who could cold set the rear triangle and correctly align the frame.
The question is: will the frame survive the bending with 100% integrity?
