I got my zipp 404's mounted up on the bike and noticed the hubs have some side to side play in them, more than what I'm used to in a bike wheel. Zipp's website says some play is normal because of their bearing design. Is this a similar experience with other Zipp owners?

I got these used and ordered new front and back bearings from zipp anyway. I cleaned, lubed and torqued everything to spec and they felt great in my hand, but a little loose clamped on the bike. Maybe the new bearings will tighten things up a bit.

Thoughts?
