Work at a velodrome, we have 79 bikes with Primatos so quite experienced with them, the others not so much.

Personally though, the spider/arm interface on the Rotors looks like a weak point. I have experience of other cranks that use similar systems (like middleburn) and wouldn't recommend them for fixed use outside of a velodrome.

I agree, it does seem like a weak point, but it seems like the garish old Rotors hold up fine to everyday use, whereas the newer ones don't. Do you know anything about how the system has changed, and the differences between the spider designs that makes one durable, and one total cheese?

I'm afraid I don't.

Manufacturing tolerances would need to be pretty tight to eliminate any chance of play developing, maybe they've slipped recently?
