• What am I missing here,

    Left is a 68x107 un55
    Right is a 68x110 un55

    Driveside axle projection is identical, the extra length on the 110mm is all on the nds.

    Surely it should be 1.5mm either side?

  • You'd think so wouldn't you!

    You could try a bodge using a ~1.5mm BB/cassette spacer on the DS cup?

  • Square taper BBs aren't necessarily symmetrical. The detailed specs will tell you what the DS and NDS protrusion will be.

    The 110 seems to be particularly asymmetrical. Presumably it's designed for a specific chainset model - maybe to push the left crank out to match the extra width of a triple on the right hand side.
