I recently purchased for cheap an old Peugeot frame, probably a U08, that came with bottom bracket installed. I took it out to have a look and to grease it up... the spindle and the bearings are still in good shape so i thought it would be fine to keep using. So far so good but now I am pretty ultra confused about how to find the correct cranks. It seems more often people decide on BB based on the cranks they want, rather than they other way around, and that does make sense since the BB seems a lot cheaper. I just want to make a determination if this BB will work with the cranks i want.
My BB is 68mm wide (good so far)
and the spindle length is 126 mm... that seems to be longer than most.
When companies refer to BB sizing is it the spindle length that they are really referring to? Is it fair to say my BB is 126mm?
I was thinking about getting something along the lines of the Sugino RD 165mm crankset Sheldon Brown suggests:
I guess for another $30 I could get that matching BB that would definitely work with this, but it would be nice if the old one would fit.
I haven't been able to really nail down any solid info on how to determine if a certain set of cranks will fit a certain bottom bracket. My BB is square tapered, and I understand there are basically two camps, divided by Asian vs. European? So assuming my Peugeot has the original BB in it, it seems possible that Japanese cranks might not work with it?
Furthermore since eventually I am planning on making this a fixed gear it seems like having a 126 mm BB could result in chainline issues? Beats the **** out of me.
Please correct my rampant errors, misunderstandings, pathetic attempts at comprehension. Sorry I am such a DUNCE and RANK AMATEUR and PUERILE NOVICE etc etc. Thanks in advance to anyone who can clear up some of my confusion.
