• Omniums are GXP, right? Surely removing the NDS BB spacer will push the crank over to the right and give you more chainstay clearance?

  • From what I understood the spacers are only for wide axles or smaller shells, and it's not advised to use them.

    Here's without spacers.

  • That's with no spacers on the non drive side too? The spacing isn't determined by the drive side cup

  • That's not right. Should be no spacers at all, and cups flush to frame with a solid 4mm between stay and spider. I'm running a 50t ring with plenty of space for bigger.
    Try different crank if you have access to or send back to Dolan.

    @TomvanHalen between the BB and spider? If so, that's normal. If I remember on another thread, Tester might have said that the DS is machined to stop at a certain point as not to compress the bearings, leaving a little space between spider and bb.
