Iliac Arteries

Reading on the CN main site about Bib Jungles being the latest victim of Iliac Endofibrosis, it occurs to me that a) I wasn’t even sure where the iliac artery is, and b) it’s getting more and more common in the peloton, I wonder if there are preventative measures that riders should be taking.

The Iliacs do seem to be right in the position where most movement is happening on a bike, and I can imagine that if they’re in any way restricted, that pedaling along at 100+ rpm won’t make it better.

Is there a bike fit solution? A more open hip angle, or wider q-factor? Has anyone on this forum ever experienced it, or is it something that is almost unique to pro cyclists? Do I have it and is that why I’m so slow?

The Iliacs do appear to be in the area of the bike where the majority of movement takes place, so I can see how pedaling at a speed of more than 100 rpm wouldn't help if they were in any way constrained.
