I am looking to build a road frame to handle 50+mm tires. I want to use lugs so I will need to bend and crimp the chainstays to make clearance for the tire. The issue as I see it is the starting angle from which the stays exit the lugs at the BB so bending is a requirement.
What is the best method to use since I need to make the bend in a very short distance?
Plus, I need tips on crimping the interior and exterior of the tube for clearing the tire and chain ring. Thanks in advance.
