For the drive wheel. All the current bikes, except the T50, have closed dropouts, but still use QR hubs. It's just the nature of how the front-end is put together. So you have to remove the skewer, put the wheel in, and then thread in the skewer. Because the dropouts are closed, you cannot torque your wheel out, even with disc brakes.
For the rear wheel, regular open dropouts on all the bikes.
