Combining two unique technologies, SteelFiber FC “Flight Control” graphite hybrid shafts combine the composite technology of SteelFiber with a tip section optimized for players who need higher trajectories.
Design & Technology
- Thinner wall thickness for improved feel
 - Superior hoop strength for increased stability and energy transfer
 - Perimeter weighting, shifting the shaft’s CG outward–increasing the shaft’s MOI
