Hi Guys,

I recently bought a used Niner One9 which has the old style EBB. I was reading on Niner's site about the new EBB, that it solves the issue of "ovalization" of the BB shell.

Have any of you had this problem? How tight should the set screws be to prevent movement or creaking, but not cause this issue?

Is it worth the dough to upgrade to the new one?

Thanks!

I have used the old type for over two years in countless positions, both for singlespeed and geared without a sound or slippage.

You should at least give it a try before you discard it.

I tighten my set screws as tight as I dare.
