Shaft | SPHERE 3K Xtreme - Carbon - 7,7" or 15"

The SPHERE 3K Xtreme shafts in 7.7" or 15" lengths are specifically designed to build bolts for the Cobra System, R9 and Adder crossbows and, like all SPHERE 3K Xtreme shafts, feature a patented structure with integrated, high-strength 3K carbon weave and an outer diameter of up to 7.45mm. The lightweight carbon shafts have an optimised wall thickness just for this purpose to enable longer durability and to produce impressive arrow speeds.

The 3K fabric is also responsible for the stunning matt black appearance of the SPHERE 3K Xtreme. The "3K" stands for the number of 3000 filaments (fibres) that have been processed per carbon strand and are responsible for the typical cross-wound carbon look.
