Firenock AeroConcept Carbon Inner Tubes are made of high modulus carbon tube with 6 inches length.  These tubes are specially made to integrate with Firenock AeroInsert D/H (double shoulder type) inserts to form AeroConcept System.  AeroConcept System can strengthen and stiffen the arrow (i.e. increase spine) especially the arrow front end without adding much weight to the entire arrow shaft.  Moreover, precise weight adjustment of the entire arrow can be achieved by just adjusting the length of the carbon inner tube (i.e. a longer tube = greater weight and faster arrow straightness recovery or vice versa).
