Long throw quick release
Everybody is aware of the safety tabs on fork dropouts to prevent accidental loss of your front wheel. Most roof rack systems offer long throw quick release levers so that you don't have to readjust the quick release nut every time you use it to carry your bike.
Is there any reason why a long throw quick release to clear the safety tabs wouldn't work on a bicycle hub? Does somebody even market one today?
