• Can you check if there's a spacer on the DS spindle? (between the wavy washer and the crank).

    The other thing I would do is face the shell, as it look like it got paint on it, it won't make that much of a difference but worth doing anyway.

    Your other option is running a Shimano hollowtech bottom bracket with an adapter to convert NDS to 22mm.

  • Thanks. There are no spacers anywhere - not even a wavy washer at the moment. I'll look into getting the LBS to face it.

    Does anybody know if the ITA cups should be narrower than the bsa ones?

  • Does anybody know if the ITA cups should be narrower than the bsa ones?

    The fixed axle length and wider shell sort of dictates that they have to be right?

    I wonder if they are specific Italian shell cranks with a longer spindle?

  • I'll admit that also have me stumped, only way I can diagnosed is to have the bike with me.

    I may have an italian GXP at work, so I'll find it and measure it so you can compare it.

    The other quick solution is to try an Italian Shimano hollowtech bottom bracket plus adapter on the NDS to run the GXP spindle.
