Thanks! I also read that 7600 cranks work fine with 107mm Jis spindles even though they sit 'better' on iso tapers. I could also get an skf bb 110mm, iso, french thread for the bargain price of 150€ :D probably not... Btw, the beater rear wheel I bought from you is still going strong ;)
I think the answer is to get a two mm longer bb https://www.lfgss.com/comments/8756147/
