Chain Stays??
Well we have been back for 2 weeks from our European cycling tour and I am already planning the next build!
Here is where I could use some help. Chain Stay selection. How do I find the actual shape of them? Ceeway give a Columbus link but I don't see anything there.
My idea for this fram will be uan eccentric BB. I already have 2 from QBP. But CS shapes...
Advice and guidance would be great!
Thanks!

Do you mean this?

It does seem to just go all black for me after a few pages. Maybe just find an older one.
When you say shape do you mean the ovalness or the bends? Basically the cross-section at the end is mostly about 30mm/18mm oval or 22mm round. I think round/oval/round is better, although tricky to weld since it's quite tight between them. Doable though. Idk about fillet brazing.

Framebuilder supply has drawings for all of the Columbus chainstays that they sell. You should consider looking at US based sellers like Framebuilder Supply, BikeFabSupply or Firsthand Framebuilding. Most shipping companies are no longer shipping to the US due to uncertainty and collection issues around tariffs, so you may have issues trying to order from Ceeway.

Just looked at Frame Builder Supply. Maybe I am missing something but the only drawing I see is a cross section of the tubing not a drawing of the overall shape.
