Opinions on this possible 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.

  • 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.
