Quick release prevents wheel spinning freely I just got brand new wheels for my road bike.  All was looking great until I tightened the quick release on the front wheel (not too tight, I can close it with just my thumb and one finger) and now the wheel doesn't spin freely.  Seems to happen a little bit on the rear wheel too.
Is it normal for this to happen a little, like on the rear wheel?
Is there something I can do to fix the front wheel or should I return it as faulty?
Edit - The wheel uses cartridge bearings and the end cap is just a push fit; there is no cone or locking nut
As you correctly observed, quick release tension affects hub preload.
To fix this, adjust the bearings of the hubs so that they are correctly adjusted with the desired quick release skewer tension. You need cone wrenches for this adjustment.
From the bible:

Although small, axle compression on QR hubs is large enough to alter bearing clearance and should be considered when adjusting bearings. Bearings should be adjusted just loose enough so that closing the QR leaves the bearing with a slight preload. Excessive preload from QR closure is the cause of most wheel-bearing failures not caused by water intrusion. Clearance, in contrast, can be felt as disconcerting rattle when encountering road roughness.

If the wheels are new and are supposed to be working fine, you could consider sending them back and demanding a correctly adjusted hub.
