• That is a cracking looking bike! It is going to fly I'm sure.

    BB length should apparently be 111mm for Centaur double.

    Note also that Campagnolo/Tifosi BBs are ISO taper. Shimano and basically all others are JIS. They are not interchangeable. So a 111 mm JIS (Shimano) BB will put those cranks in a different position when compared to a 111 mm ISO (Campagnolo) BB.

    Also just double checking - are you using carbon-specific brake pads? If you need to buy some I can recommend Swisstop yellow pads.

  • Thanks!

    Ok amazing, I think I have a 111mm about so will try it. I'll keep in mind ISO/JIS as well, thanks for the heads up.

    And yes, got some Swissstop Flash Pro's

  • Hi,
    to corroborate what Ndeipi said:

    caveat: Campag usualy makes the bbs that fit their cranks and brands them as the same GS. What follows is an educated guess:

    centaur square bbs came in 111 or 115.5 which is probably double and triple. These are ISO.

    JIS tapers have the same angles but are a bit fatter

    "If you install an ISO crank on a J.I.S. spindle, it will sit about 4.5 mm farther out than it would on an ISO spindle of the same length."

    so your shimano (JIS) spindle would need to be 102mm and to complexify a bit more, I would imagine that if you do find a 102 JIS spindle, it could be the low profile kind which will have a different compensation factor.

    ebay is your friend
