Subject: [CR]Lugs limiting frame geometry

Adept framemakers were not limited by the lugs. They forged them, bent them, cut em open and rewelded them, made their own lugs, whatever it took.

Pop Brennan took 68 degree head angle Brampton cast lugs and reworked them to 74 degrees for his track bikes. In some respect the bikes look like they were crashed!
