Looks like I'll be doing a tandem this summer so I've been looking at whats current with EBBs. The improved Niner EBB looks interesting.
Has anyone used one on a frame build?
From what I can tell, it needs a 55mm id bbshell and I have a couple, but they are (I think) 62mm wide. I cant find any specs on the Niner shell width....anyone happen to know that?
