• And it’s not like an Italian BB will fit as while the TPI is the same it’s 1mm bigger shell. you could maybe recut the wrong side to an Italian bb but then you have to buy 2 bb’s.
    bit of a conundrum but it could potentially be solved by a frame builder without fitting a new bb shell.
    agree it’s shit QC

  • Given they were specced as BSA not really.

    None of the Isen models have BSA BBs.

    It does happen that Paragon thread a bb shell incorrectly but it is extremely rare.

    Not to doubt your anonymous messager but without sharing proof, there's not much point in posting about it here.
