Those max weight claims are written for lawyers. Just to be clear, the wheels on our tandems are pretty much one-offs. Zipp does not build/sell tandem wheels for the public. That's why they won't recommend it to others. ENVE does though. They are on par with Zipp and they have no weight limits on any of their wheels!

As far as using them for daily use, we may disagree but, I don't find them any less robust or reliable than any of my other wheel sets. The only reason (and it's a good one) to not use them daily is the cost of replacement if you do have an issue. If you trash a set of Deep V's it isn't going to set you back $2500! I think it's a moot point here anyway because the OP wasn't planning on using them daily.

The DA rings do look pretty sweet on the Calfee. They make the bike look as fast as it is!
