What can cause your wheels to spin less freely? I remounted the rear wheel on my trike, and only touched the QR. Now when I spin it, it doesn't spin even half as long as the front wheels. Same thing, only more pronounced on my old bike, though I admit taking a quick look at the bearings on that one...
Could it be the QR, the bearings, or what? My QR is tighter this time on the rear wheel, but I thought they are supposed to be very tight?

Could be QR, bearings, or both. Changing tightness of QR (probably) changes bearing preload. Increasing preload past optimum point actually adds drag ... and puts needless stress on cone, bearings, bearing race.

In many rear hub designs the cassette bearings also rotate when coasting, adding to the drag.
