Bottom bracket advice

[secret_squirrel]

Howdy - anyone know or willing to guess the bb spindle length for a set of campy black mirage cranks and a set of mid 90's sachs new success cranks?

most lower end square taper campag stuff from the 90s onwards seems to sit on a 111mm ISO axle.

the Veloce square taper BB is a bit porky, but is readily available and lasts well.

Cool - I have an 110mm knocking about at home so will try it. Hopefully the Sachs will be the same as they were sometimes made by campy too.

Campag needs iso taper not jis. They are subtly different

I've got a 111mm Campag BB which you can have for postage. It's got a little bit of play, but will get you started.

If the Sachs ones are by Campag there will probably be a marking somewhere that gives the game away, especially on the rings if it still has the originals. Earlier (pre-1994/1995??) New Success chainsets were sourced elsewhere - I don't think Sachs made their own; the ones in the link seem to be by Thun of Germany - and designed to work with SKF bottom bracket units:

Dunno if those were JIS or ISO though.

Thun chainsets are JIS...at least the ones on my tandem are.

iso BBs usually fit JIS cranks well , as long as the end of the axle doesn't protrude into the bolt area. but the Q factor will be 1 or 2 mm narrower than advertised
