mixed lugged and lugless?

Posted on
  • Hoping I could call upon your collective frame wisdom please...

    I've seen an old steel frame for sale that is lugged everywhere except the seatpost joint where it seems (I think) to be fillet brazed. Is this normal? Is it more likely a sign of repair?

    Any guidance would be greatly appreciated. Especially if there's any way to tell if it's safe (hard from a couple of pictures I appreciate)

    Many thanks

    Dan

  • It's not super common but not completely unheard of.
    One reason could simply be that lugs come in preset sizes with the tubes at predetermined angles. They can be tweaked slightly but if the builder wasn't able to get a lug to work the way they needed, it could have been easier to braze it. It could just as easily be a design choice.
    It's unlikely to be a repair as the seat post binder is a separate piece brazed on the top of the tube and you would expect in most cases for this to be incorporated in the lug if there ever was one.
    If it's a repair, it's probably a full seat tube replacement and unless you have reason to believe it's not safe, I'd have no doubts about it personally.

  • Thanks @PhilDAS - very helpful
