Guys.
A recent acquisition - a Roberts built Geoffrey Butler (dated 197
race frameset that has a Portacatena dropout.
Question; does a frame designed for a Portacatena normally* have a cutaway chainstay on the dropout end ? I don't have the Portacatena but the frame looks like it will either accommodate it or a 6 speed freewheel not both.
Thanks.
Jon.
*suspect the answer is yes.
