Quick release and thru axle parts
Classic quick releases have a lever and a locking nut. They thread through the front and rear axles into the hub body, which absorbs the load. They allow a quick and above all things tool-free removal of the wheels, which is particularly practical if you travel a lot by car. But be careful, a wheel with quick release will not fit into a fork with thru axle, and vice versa. Thru axles use a bolt that goes through the axel and bolts directly to the frame. They offer an extremely positive and true connection to the frame and are believed by many to be an improvement on the older release system.
