Hi everyone, we had a customer ask us to cut off a downtube mounting boss from a steel frame. He wants to run a dropper post with the cable routed through the downtube.

We highlighted we weren't entirely comfortable with the work, and agreed that if he's OK with that, we'll take on the work.

The work was done, and I'm now worried about frame integrity.

I'm worried the hole is too large. Looking for someone to help soundboard my concents. Is this hole too large, is the frame totaled, etc; any context would be appreciated.

Note the boss flang is still partially visible.




Best,
Dan
