Most high end Japanese BB's were not JIS. JIS was used on mid to low end stuff, of which Sugino Maxy was typical. The Sugino Mighty BB was a Campy clone. I think that might also have been true of early Dura Ace, although I believe the later Dura Ace BBs may have been sort of unique, neither Campy clones nor JIS. I also seem to recall that when Rivendell was selling some late Superbe cranks they stated that they took a special BB, although by that time, the Campy NR BB was long out of production, so an NR clone at that point might have been viewed as "special".

Maybe it's just an Aussie thing but most every used campagnolo crankset i've been looking to buy down here has been used with a shimano (or another brand) bottom bracket. Knowing that the tapers are different I'm wary of buying such cranks that may have been defiled. So .... what gives with mixing JIS with ISO and am I right to get all preachy with these neanderthals who are corrupting otherwise good cranks? Or is there no issue and they are OK to use? This matters most to me because Im thinking of track cranks and am hoping I'll have the right (or proper spec.) chainline.

oh yeah, speaking of cranks ..... WTB - an early chorus 170mm left crank arm. croce d'aune is a maybe, prefer visually challenged (meaning cheap) for my early 60's aussie built sport-touring grocery bike. OK OK .... the only groceries I'm buying is beer, but doesn't that make the bike even more crucial to my well being? Just want a mate for the right hand chorus orphan I have ...... lemme know if you have sumtin'

more importantly ... surf is 2 foot and OK for the mini-Mal. Water is a nice 22 degrees (celcius) and the 'kini crew are out in force (God bless 'em). Gotta head out before the wind changes direction .... a not too hot 29 degrees and not a cloud in the sky ;)
