Yup. Sling a bit of braze over it and worry about it in a couple more years?
I’ve outlined what I think are the edges of the weld in blue and what I’m thinking is the crack in red.
Bother drilling the ends?
Looks like a crack to me. Stop-drilling the ends is sensible (if done well) but make sure you actually hit the ends of the crack.
Doing some corrosion removal and touch up on my mattress Steamroller and I’ve noticed this at the seat tube/bb shell weld.
I just can’t tell if it’s a crack or not.
At forest I thought it might just be the edge of the weld but I think it does actually go through the weld.
