To ensure the highest clamping force possible all NC-17 quick releases use a copper bush rather than plastic or aluminium for the QR leverage surface. By using copper it is possible to achieve higher clamping forces with less effort at the QR lever. This higher clamping force means that even with big disc brakes being used you will achieve precise and direct steering with little torsional deflection of the front wheel.
