Cold Setting Front Triangles

As for the tubes, they are a 46mm headtube, 38 mm downtube with a bend (29er family columbus) and a 28,6 toptube. I think the downtube is too ridgid to bend well and will probably fail spectacularly when coldsetting :-).

Yup I think that is way too beefy to cold set!

@normaali has posted some great videos and info on flame straightening:

[Screenshot_20230604_220051_Drive] Interesting topic! I have extremely poor heat control while welding and I use flame straightening on my frames (aka magic wanding). I began after reading the NJS builder Level using it in Bicycle Quarterly. It’s super effective even on frames, that won’t cold set jumping on the head tube. This AGA video is my bible: [AGA Historical Archives - Flame straightening in welding - English]

I found their demo very eye-opening:
