In the example below you got a fatbike with pressfit shell and 100mm motor.

Grey lockring can fit, but black triangle bracket would just be contacting the pressfit adapter anyway so this is non-optimal even if the length were good enough to fit both lockrings with motor flush with triangle bracket. So while the assumption may be to use a longer motor, in this instance it would be pointless.

Solution is to use a BSB stabilizer bar instead of the black triangle bracket.
