Anyone got any opinions on this,
I decided to use Columbus cx bend chain stays in order to get the tyre and chain ring clearance I need on this large tyre fixed frame in building for my mate.
Because of the bend in the stays, when inserted into the ports in the bb shell they want to sit very close together at the wheel end.
It’s easy enough to pull them out to where I need them (120mm spacing) but they do start to pull away from the tangs on the ports on the bb shell.
So I’m not sure if I should braze the stays in where they have good contact with the bb lug then cold set them to where I need or hold the ends out where I need them and deal with the gap before/during brazing?
I’ve tried coercing the ports a bit but they just want to bend at the ends of the tangs, not take on a proper ‘set’.
These photos show the stays inserted to the ports and sitting narrow. Getting good contact with the lug.
