Re:
Pass, I'm no welding expert. The titanium bike frame welding experts didn't mention distortion as being a problem, only that it could last two years or two weeks.
Currently the frame is wall art, if the welds don't work it will still be wall art that cost £40 more.
I will do lots of before and after pics etc. Stripping down bike and dropping frame off beginning of next month.
Fingers crossed.
