Carbon Express Nano Pro X-TREME Shaft
The Nano Pro series shafts are simply the best 100% carbon rods in the world for target shooting. These shafts have been specifically designed for long range FITA, NAA and NFAA shooting.
The standard Nano Pro shaft, designed for use with the compound bow, are shafts with constant spines over the entire length. The NEW Nano Pro X-Treme rods, on the other hand, are designed for use with the recurve bow and have different pins along the entire length, with weaker pin values at the tip and end, with the lowest value at the end for perfect fletching.
