I own a Kuat Transfer 3. They also sell a double tray instead of triple tray. I've had it 3 years now. It's the kind that doesn't touch the framesets. It has held up to rain and use fine. Nothing is worn or broken yet. A lady has hit it with her Mercedes and driven off with no damage to it, just damage to her car.
If you own "carbon fairing" wheels, you do need to remove the rear wheel and replace with an alloy version to transport so the ratchet strap doesn't crush the thin fairing.
Also, there is a small design flaw (in my opinion) where the way that the optional thread-in lock system threads into the wrong side. Meaning, as the rack goes over bumps the motion slowly tries to loosen the thread-in lock instead of tighten it. Not a big deal.
It doesn't look as super nice as the NV, but it works. The cups or trays are also pretty darn big, so it would probably fit a MTB or Fatbike size tires fine also.
I got it on sale at the LBS as it was the display model. I would buy it again.
