Bottom Brackets Comparable to Mavic 610?
 

Im a huge fan of the Mavic 610 (sealed bearing, super smooth etc), but this time around want to avoid chamfering the bb shell.

Which bottom bracket would you guys suggest? I was looking into Omas and such, but just Im sure members here are much more familiar with models that Im unaware of. Thank you.

Mavic did issue an earlier, conventional BB, I think, with their 1000 group.
Problem is, they are hard to find, and so far the only ones (for some reason, usually beat to hell) I did find are either French and Italian threaded. Haven't come across one with BSC threading....
you could just look for a Stronglight BB, if you want something French, with sealed bearings. I think the one the issued with their Delta group had sealed bearings and had lock rings on both cups, so you get a little bit of chain line adjustability.

Phil Wood. Really top notch and adjustable chain line. Other than that, good ol' Shimano UN series BB are excellent.

Im not looking specifically for french threaded bb.. I just love the Mavic 610's performance, (which I have on 2 of my bikes both english threaded I believe, not that it matters since its chamferred) and wanted to find something comparable in performance.

What type of crank will be used, ISO or JIS?

ISO. Wish I could use 10speed cranks but unfortunately not compatible, so ISO
