From a quick glance it looks like a frame design issue.
That was my first impression, but I contacted the manufacturer and they have indicated it might be an issue with the cranks and the built up bits at the back.
I'm happy to accept this for now, as they do seem to bulge a bit and would fit otherwise. I'm curious if any other Omnium users out there have these chunky spider endpoints, and is this atypical of track cranks or what.

The chainstays are straight btw.
