  • Having a bit of trouble with my new BB, Shimano Dura Ace BB 7700 fitting it into my nagasawa. It the bb won't thread onto anything. Its as if the bb is too big for the shell? Sorry if I am being stupid, I haven't ever used one of these BB's before :/

  • it says 36x24 meaning italian thread which is for 70mm shell. 1.37x24 is english threading and for 68mm shell.

    so you need to get a different bb. or maybe only cups will suffice.

  • Ah okay. The bb is the octalink thingy. I hate them. So my BB is italian threaded.... So if I get an English Threaded Octalink BB it will all be good. Thats alright then ill be selling this set with two BB's when I sell so gives the next user more scope on the frame choice. That is if I sell

    Thanks @rodolfo for the obvious explanation (I don't know much about bb's) :?
