How bad is this seatpost crack and what can be done? (Columbus Thermachrom steel)
Overtightend the seatpost collar and did this to my favorite bike in the world. Since it's not load bearing, I was hoping there's a reasonable fix to this. It's been surprisingly difficult to get a local store or framebuilder to give me a quote or suggestion on what to do. I rode it for a bit after doing this unknowingly and it hasn't gotten much worse.
So far, the range of options is: braze in a lug (most extreme) to bead weld it to hold the crack. Looks like the seatpost is a bit too small, so maybe weld in a shim?
Any help is greatly appreciated...
